Are You Complying with CPRA/CCPA Opt-Out Rights?

Under the California Consumer Privacy Act (CCPA) that went into effect on January 1, 2020 and the recently approved California Privacy Rights Act (CPRA) that will supersede CCPA come 2023, California residents have the right to opt-out of a business selling or sharing any of their personal information.

That means that if you are a for-profit entity with an annual gross revenue in excess of $25 million and handling personal information of more than 100,000 California consumers or households, you are required by law to provide a clear and conspicuous way for your customers to opt-out. But what exactly does the right to opt out mean, how is it implemented, and how can you ensure your business complies?

What Does it Mean?

When you give customers the option to opt out, it limits the extent to which your company can sell or share a customers’ personal information. Under CCPA/CPRA, personal information is considered any information that identifies, relates to, or could be linked to an individual or household. This includes information like name, social security number, email or IP address, Internet browsing history, product purchases, geolocation data, and professional or employment-related information—essentially any information that is not publicly available via federal, state or local government records. According to Section 1798.140 of the CCPA, personal information also includes any information used to create a customer profile that reflects preferences, characteristics, behavior, or attitude.

The opt-out requirement doesn’t preclude you from collecting personal information in the normal course of doing business. After all, your business needs personal data to fulfill purchases and enable transactions. Opting out just means that you can’t sell or share this information with any other entity—unless it is a service provider that is necessary to perform a business function. 

It’s important to note that any disclosing of personal information deemed as providing monetary or other valuable consideration is considered a “sale” under CCPA. While often disputed, this broad definition includes the use of third-party advertising and analytics cookies that track a user’s browsing behavior. This does not apply to first-party cookies required to perform essential functions on your website, like remembering which products a customer has placed into an online shopping cart. 

How is it Implemented?

Under CCPA/CPRA, businesses needing to comply must provide two or more methods for submitting requests to opt-out, including an interactive form accessible via a clear and conspicuous “Do Not Sell or Share My Personal Information” link on the business’ homepage. Other acceptable methods include a toll-free phone number, designated email address, forms submitted in person or by mail, and user-enabled privacy controls such as a browser plugins or settings.

One way of providing an opt-out method is via an interactive cookie banner on a website that allows users to decline or accept any non-essential cookies that collect personal information. Some also get a bit more specific and allows users to select only necessary cookies that enable core functionality to help improve the customer experience while preventing the sale or sharing of data for marketing analytics or targeted advertising. 

CCPA/CPRA also has more restrictive “opt-in” requirements for children. This means that businesses cannot sell or share personal information for consumers less than 16 years of age without specific affirmative consent, with parental consent required for anyone under the age of 13. Unlike the opt-out option, opting in means that consumers are opted out by default and must take action to opt in. While this is contingent upon the business having knowledge of the age of the consumer, CCPA/CPRA does not allow a business to deliberately disregard a consumer’s age. Any business that targets children would therefore be wise to only use the “opt-in” option or implement a means to identify age to turn off any default selling or sharing of information for anyone under 16. 

A privacy policy is also mandatory under CCPA/CPRA Per CCPA/CPRA, and to collect any personal information, businesses must provide notice or disclosure about information being collected and for what purpose at or before the point of collection. If a business wants to collect different personal information than what was originally disclosed, they must provide a new notice. It therefore makes sense for privacy policies provided at the first point of collection to be broad enough to cover all information being collected. Businesses can meet the notice/disclosure requirement by providing a link to their privacy policy as part of an initial cookie banner. 

How Can You Ensure Compliance?

While providing customers with the option to opt out may seem straightforward, it isn’t enough to just include an opt-out option and privacy policy on your website—you also must immediately stop selling or sharing personal information as soon as a user chooses to opt out. You also need to wait a year before requesting authorization to once again sell or share their personal information. And if you are the third party purchasing information, it’s your responsibility to ensure that the data is from individuals who were given the opt-out option and clearly chose to opt in.

It is also recommended to conduct a thorough data mapping to identify all the ways your business and its systems handle personal information. This can help you determine if any third-party cookies are enabled on your website or if any of your data handling constitutes selling or sharing personal information. Because even if you think you aren’t selling or sharing personal information, it’s not always as obvious as disclosing data to third-party advertisers—think credit checking, identify verification services and other cloud-based services. And if you are unknowingly selling or sharing personal information, you’re still liable.

What Media and Entertainment Companies Need to Know About Data Privacy

Media and entertainment companies pay close attention to cybersecurity; after all, you can’t run a video-streaming service like Netflix or Disney+ without putting top-of-the-line safeguards in place to protect your media assets and ensure continuity of service. But how many media and entertainment companies can say, hand on heart, that they put the same effort into protecting their users’ data and privacy rights?

The irony is that, as the success of M&E-adjacent companies such as Facebook has shown, data itself is rapidly becoming a core asset for media companies. So far, though, few firms are investing sufficiently in the technologies needed to handle an expanding data universe, or to manage compliance in an increasingly demanding regulatory landscape. 

At Ketch, we understand the relationship between media and tech. We the founders previously built Krux, working with media giants including Time Warner and Meredith to serve over 20 billion page views per month. So I speak with some authority when I say: if media companies don’t solve their tech stack, and put effective systems in place to manage privacy and data governance, they will face serious problems in the months and years to come.

The golden age of M&E

Ironically, this challenge stems from the fact that media companies are currently enjoying something of a golden age. Increasingly, M&E brands operate across a wide range of platforms — mobile, TV, game consoles, the Web — and an even wider range of jurisdictions. Look at Netflix: whether I’m in Caracas, Caen, or Cincinnati, I can fire up my laptop (or my phone, iPad, Roku box, or just about any other gadget) and instantly access a wealth of streamable content. 

People aren’t just accessing media at home: they’re logging on at the gym, in schools and workplaces, during commutes, and even on long-haul flights. But precisely because M&E brands now touch so many parts of people’s lives, they face increasing scrutiny from both consumers and regulators. 

People pay real attention to media companies, and have a direct and intimate relationship with them, so data breaches can do real brand damage. After all, if an anonymous ad company exposes my personal data, I’d be annoyed — but if my favorite media company messes up, I’d feel utterly betrayed. When Sony’s PlayStation Network got hacked, exposing 77 million users’ data, it took years for Sony to regain gamers’ trust. 

Game on for regulators 

Media companies are more likely to be punished by consumers for data breaches, and they’re also first in line to feel the impact of new privacy regulations, because they interact directly with both content and consumers. The entire downstream universe of ads and marketing relies on data and consent information collected by M&E companies, and regulators are paying close attention to the way that media companies meet their obligations to consumers.

Further complicating matters, media companies are seeing regulations such as the GDPR used as an offensive weapon. Data protection laws (and especially data subject rights such as the right to be forgotten) are being used alongside defamation law to raise objections to content, making data management a high-stakes area of special interest for M&E companies. 

Media and entertainment brands also face additional regulations regarding their handling of users’ content-viewing and web-browsing histories, their decisions when using interactive content, and so forth. The stakes are especially high for companies that cater to children: parents care deeply about how their children’s information is handled, and many data laws have stringent provisions governing minors’ data.

Media companies must also monitor regulations that govern access to services across multiple jurisdictions. The European Union, for instance, now requires that media subscriptions purchased in one member-state remain valid in other member states, so an Italian Netflix subscriber must also be able to log on to local services when traveling in France or Finland. That requires companies with multinational presences to seamlessly coordinate privacy and consent across their national sites and services. 

The fragmentation of data tech

Inevitably, as M&E organizations spread across multiple platforms and jurisdictions, their data-tech solutions grow fragmented. Dealing with a complex world, companies implement complex fixes — and in doing so, they create a hodgepodge of tech solutions incapable of delivering the streamlined, joined-up data infrastructure they need to succeed. 

Unlike finance or health companies, where data security has always been a priority, M&E organizations haven’t historically had to worry much about these issues. It’s only now, with the explosion of data applications and the sprawl of global regulatory frameworks, that media companies have found themselves forced to try to evolve new capabilities, and rapidly add in-house data expertise. 

To cope, media companies urgently need a new approach: a data-security solution that can sit alongside their existing tech stack, and serve as a single point of truth amidst the complexities of their tech architecture, their vendor ecosystem, and their own corporate structure. After all, media companies are made up of sub-organizations within sub-organizations: companies like Warner, Sony, or Disney aren’t single entities, but rather amalgams of different tech and media operators. Now more than ever, these organizations need a way of ensuring all the different parts of their M&E empires speak the same language when it comes to privacy and consent.  

Ketch is the solution

The good news is that help is at hand. Ketch serves as the connective tissue enabling media and entertainment companies to manage data privacy and consent across their sprawling, interconnected business functions. 

Here’s how it works: using a simple dashboard, your legal specialists determine how different regulations affect your business, and create policies that define how data can and can’t be used. Ketch then turns those policies into a single unified reference system that developers from across your organization can use to check how any given piece of data can be used.  

Your legal team never has to weigh in on specific data-usage questions — they just set the overarching policies, and let Ketch do the rest. And your developers and engineers don’t have to fret about interpreting regulations — they just use APIs and other standard coding call-outs to check whether a given operation is permitted.

That means your legal team can stay focused on interpreting regulations, while your tech team can keep driving innovation forward. Ketch provides only the guide-rails that are truly needed, and stays out of your way the rest of the time — and that leaves you free to do whatever you want with your data, as long as it’s consistent with the regulatory interpretations you’ve implemented.

A richer experience

The benefits aren’t just internal: data managed by Ketch stays protected even when you work with outside parties. Because we extend through your whole vendor ecosystem, integrating both upstream and downstream, your users’ data is kept safe and handled appropriately even when you hand it across to third parties for ad-tech purposes or other permitted applications. That adds up to a seamless, flexible, and robust solution that allows media companies to provide exceptional experiences without compromising on data security. 

Because Ketch lets you deliver just-in-time solutions, handling privacy and consent doesn’t detract from the user experience. With Ketch, you can wait until the exact moment that consent is needed (such as the instant of clicking a button or completing a form) before you make the request, rather than interrupting users before they’ve had the chance to start enjoying an experience or interacting with content. 

An asset, not a liability

When it comes to privacy and data security, media and entertainment companies are on the front lines, and the stakes have never been higher. Regulators are raising the bar, and there’s simply no room for companies to make mistakes. 

Even so, many M&E companies are woefully underprepared. Data is emerging as a vital strategic asset, but also a potential liability. To succeed, media brands urgently need a tech stack that’s able to ensure regulatory compliance without inhibiting innovation and growth. Ketch is the only solution that can cope with the complexity of the media environment, and help companies to manage data while delivering the seamless, engaging experiences their customers demand. 

So if you’re trying to figure out how to manage data privacy in the M&E space, get in touch — and find out how Ketch can help you take privacy and consent to the next level.

Switchbit is now Ketch

The Switchbit team is driven by a belief in two key principles. First, privacy is an essential human right that all businesses should have the ability to respect and enforce. Second, data is property. Like land and other physical property, data must be protected and controlled according to the time, terms, and conditions of its owner’s choosing. 

We don't see a zero-sum world where consumer privacy is protected and businesses lose. We believe that both consumers and businesses can prosper together. We're determined to help businesses honor the data dignity of their customers, while also giving them the privacy and security tools that let them preserve and unlock the power of data for core operations and AI-enabled business processes.

Since our inception, we’ve been working hard to achieve the radical simplification of data privacy, which we believe is among the most critical imperatives facing our economy and our society. Undeniably, we are in the midst of the Data Rights Revolution.

As tends to be the case with revolutions, optimism and commitment are all mixed up with complexity and confusion. In our experience, most businesses want to embrace and implement a consumer-first privacy paradigm--the question is How to get there? 

We are committed to building powerful-but-simple infrastructure that guides our customers through the maze of laws and regulations, while at the same time recognizing and capitalizing on the opportunities along the way--opportunities hiding in plain sight.

Of course you need to achieve compliance and get the details right. But the companies that win this revolution will be those that go beyond, by creating privacy experiences that inspire customer satisfaction and trust. We help you imagine, design, and offer those experiences.

One of the many hurdles here is that the maze isn’t static. It changes as laws are born and evolve. All the energy you spent getting prepared for CCPA and GDPR? Congratulations! Your prize is…. CPRA and LGPD!. Data privacy is a dynamic challenge. That’s why we’re always focused on giving our customers a dynamic, deploy-once-comply-everywhere solution.

In this relentless pursuit of simplicity in the face of change, we’ll be with you every step of the way. And today, we’re practicing what we preach: We’ve decided our name adds more where less will do, and do better. Today, we’re saying goodbye to “Switchbit” and introducing you to “Ketch.” Strong and simple, just like our product and our mission. 

Ketch is blazing a path in the Data Rights Revolution. Join us in fighting for privacy as an essential human right, and data as property to be preserved and protected.

And if you don’t know, now you know. 

Part 3: Privacy-Preserving Contact Tracing at Scale

As I previously discussed in Part 1 and Part 2, to defeat COVID-19 we’ll need effective contact tracing — but in order to win widespread buy-in for digital tracing, we must also commit to zealously defending users’ privacy rights.

In Part 3, I’ll map out the path to privacy-preserving and effective contact tracing at scale. Watch the third video explainer, then see below for more.

The good news is that this is a solvable problem, and there’s a way to bring Americans on board as we deploy new contact-tracing apps. The bad news is that when it comes to winning the trust of the public, the teams building tracing apps have a lot of room for improvement.

According to a recent survey, 56% of Americans say they don’t trust tech companies to manage and protect tracing data. That’s 13 percentage points less than those who say they’d trust government health agencies or universities with their data.

Winning hearts and minds is going to be an uphill struggle. That’s why Ketch is calling for a new initiative to develop industry-wide privacy standards — a joint collaboration between tech firms, privacy advocates, health workers, and universities. This would be a foundational step toward genuinely trustworthy contact tracing.

In practice, what does that mean? In addition to developing contact-tracing apps, we must also build digital infrastructure capable of fusing tracing and health data and delivering the actionable insights we need to curb and preempt outbreaks. Crucially, we need to do so in a way that is unimpeachably secure, and that transparently safeguards users’ privacy and data rights.

To achieve this, we need three big things:

#1 Threat Exposure Notification Protocol (TENP)

#2 A commitment to citizen control

#3 A robust privacy standard

#1 Threat Exposure Notification Protocol (TENP)

The Internet couldn’t exist without the HyperText Transfer Protocol (HTTP), which sets the standard for formatting and transmitting messages online. To collect the data needed to derail coronavirus transmission, we need a similar standard for contact tracing: a Threat Exposure Notification Protocol (TENP) that articulates how data can be gathered, stored, communicated, and shared between authorized stakeholders. Google and Apple’s new software kits empower individual applications, but we need a unified TENP to prevent the fragmentation of data across multiple tracing apps, and to allow analysts and health workers to leverage a unified data-stream as they work to thwart future pandemics.

#2 A commitment to citizen control

In developing a TENP, we need to put end-users in the driver’s seat. Only by empowering citizens can we secure the buy-in that’s needed to trace contacts at scale. That means giving users the power to seek out information on their own terms, and to decide precisely how much of their data to hand over along the way. To be effective, any contact-sharing standard will need to have the user’s Right to Be Forgotten baked into its fundamental structure. We’ll also need to ensure that users can give, withhold, or withdraw consent for the use of their data at a granular level, and also veto the use of their data by authoritarian states such as Russia and China. These are foundational issues that need to be addressed as such, and not reinvented from scratch each time a developer sits down to code a tracing app.

#3 A robust privacy standard

Finally, we need to codify a privacy standard that is flexible enough to allow researchers and public health actors to fuse potentially chaotic health, location, and proximity data at scale, but also robust enough to give users reliable control over their data. The more we can ensure privacy, the more willing users will be to share their information, enabling not just basic contact tracing but perhaps also the use of more advanced health data, such as biometric data or medical results, to spur the development of new treatments for COVID-19. The potential is enormous, but only if we can give users an ironclad guarantee that nobody’s taking liberties with their data.

At Ketch, we’ve taken the first step towards these interconnected goals by launching the Threat Exposure Notification Protocol (TENP), a new standard for sharing data across contact tracing applications, data providers, public health institutions, and policymakers. Essentially, TENP is a framework that lets tech companies incorporate meaningful and verifiable privacy and data security into their tracing systems, and also gives users, regulators, and health professionals reassurance that tracing is being carried out in an effective and secure way.

Of course, TENP is only the first step. By establishing a clear standard for data sharing, we’re enabling the kind of collaboration and innovation that’s needed — but others, from policymakers to tech companies, will now need to step up and make use of these tools. What’s needed is a groundswell of support for these ideas, driven both by users and by tech companies themselves.

These are early days, and we don’t claim to have definitively solved the privacy challenges inherent in contact tracing. But with TENP, we’ve created a connective framework that the tech industry, the healthcare sector, and policymakers can build on to develop more robust tracing tools. Now, we need collaboration and creative thinking to move the ball forward — and to reassure users, in the United States and all over the world, that it’s safe to share their personal data.

There’s still plenty of work left to do, so if you’re interested in helping us figure out how to realize this vision, please get in touch. Defending privacy while building contact tracing systems at scale is a challenge that’s bigger than any one company or organization — but together, it’s a challenge we can overcome. Our ability to defeat COVID-19, and to prevent similar crises in the future, depends on it.

Part 2: What's Holding Back Contact Tracing Success?

In Part 1,  I explained that for contact tracing to achieve the requisite adoption levels in America, tracing technologies must be accompanied by robust privacy protections.

So what does it take for Americans to lay their personal data on the line in the name of public health? Watch the second video in our series below. Read on for more.

Contact Tracing's 3 Big Challenges

Despite the runaway success of digital contact tracing in places such as Taiwan and South Korea, about 60% of Americans don’t believe digital tracing will help us beat COVID-19. Yet 50% of Americans also say they’duse a contact tracing app if one were available.

Clearly, Americans are skeptical but persuadable. To overcome skepticism and win large-scale buy-in for digital tracing, we’ll need to address three big challenges:

  1. Consumer Adoption
  2. Citizen Control
  3. The Oligarchy

1. Consumer Adoption

The first challenge lies in gathering data in useful volumes. According to Covid-Watch, tracing technologies must be used by over 50% of a given population in order to be effective. Paradoxically, the current proliferation of tracing apps and technologies makes that goal harder to achieve ––unless apps share their data each new platform further fragments the total data-pool.

Clearly, gathering sufficient data will require careful coordination and data-aggregation between platforms. That’s especially important in a sprawling, geographically and demographically diverse country like the United States. The same network effects that lead kids to use TikTok and old-timers to use Facebook, or prompt Twitter users to coalesce into echo-chambers, could drive different groups to preferentially adopt different tracing apps. Without the ability for those apps to talk to one another, our ability to curb this pandemic is severely limited.

The bottom line is that the coronavirus doesn’t respect our app preferences, our social groupings, or our demographic and geographic divisions. As new genetic testing shows, the virus simply rolls across state lines and national borders, rippling inexorably from one hot spot to the next. To counter that, we’ll need tools that can share data effectively, both with each other and with researchers and health workers.

2. Citizen Control

We need to gather as much data as possible, but to achieve that goal we’ll have to give users the right to opt out of contact tracing, and to delete any data they’ve previously shared. That’s because unless we put users firmly in control of their data, we’ll never achieve a critical mass of registered app users.

At a minimum, anyone who’s sharing personal data through a tracing app should be able to quickly and easily do the following:

  • Invoke their Right to Be Forgotten;
  • Decide for themselves how their data will be used; and
  • Explicitly block authoritarian states from accessing their data.

Many contact-tracing solutions ignore these requirements, claiming they’re unnecessary for tools based on Bluetooth-powered proximity detection rather than GPS location tracking. But while the Bluetooth solutions touted by MIT, Apple, and Google are promising, citizens seeking to manage their personal health risk need more than a scary message telling them they’ve been in the proximity of someone who tested positive.

In the wrong hands, information about the people you’ve met can be just as sensitive as data about the places you’ve visited, and users have every right to demand control over how that data is stored and shared. Control works both ways, too: some app users might be happy to freely share both location and proximity data, at least in some circumstances. Rather than forcing users to wait for alarming messages to pop up on their cellphones, we should put them in control, and let them seek guidance on their own terms.

3) The Data Oligarchy

A lot of this boils down to giving people control of their data, and using their information only in ways to which they’ve explicitly consented. That might sound like a no-brainer, but it rubs up against some of the defining challenges of our modern world.

From digital staples such as web search and email to innovations such as contact tracing, we’re utterly reliant on big tech firms such as Apple and Google to build and maintain our digital infrastructure. Necessarily, and discomfitingly, that means trusting those companies to build a neutral infrastructure that serves our collective needs rather than their own corporate goals.

Don’t get me wrong: when it comes to COVID-19, we’re enormously lucky to have Apple and Google fighting in our corner. But there are real privacy concerns that come with the tech titans’ market dominance. The rise of privacy regulations such as the GDPR and the CCPA reflect legitimate concerns about the rise of a largely unregulated data oligarchy.

We Can Get This Right

Tackling these concerns head-on, and building a system that handles privacy properly, should be a shared priority for regulators, users, health workers, and tech companies. We’ll need effective tools if we’re to solve this crisis and future ones. But we’ll also need apps that we can deploy on an enormous scale without sparking a privacy backlash. If we don’t get this right, we could be dealing with the consequences for years to come.

I’m hopeful about our ability to solve these problems and build a contact tracing network that respects people’s rights while delivering the data we need to defeat the coronavirus. In the next post, I’ll outline how we can unite to create the new data and privacy standards needed to win the fight.

Part 1: Will Contact Tracing Work?

It’s the question of the day: will contact tracing work? The short answer is yes, if we do it right. And since doing it right involves data privacy, data security, and data management –– right up our alley at Ketch –– we created a three-part series on contact tracing challenges and solutions .

To kick off Part I, here’s an overview video on how contact tracing works and what’s at stake. Read on for more.

A Tale of Two Countries

In mid-March, the United States and South Korea had each seen around 90 coronavirus deaths. By the end of April, however, the two countries were a study in contrast. South Korea lost just 85 more people to the pandemic — while the United States lost over 62,000 souls, at an average of 85 COVID-19 deaths per hour for the entire month.

The key difference between the two nations isn’t their size. It’s that from the earliest days of the COVID-19 crisis, South Korea implemented “virtuous surveillance,” or the use of digital contact-tracing technologies to track the movements of coronavirus carriers, identify people they may have infected, and help public health officials to break the chain of transmission.

Here in the U.S., we’re only now rolling out contact tracing at the start of May. Health experts are calling for a $3.6 billion push to support the effort, following successful examples in South Korea, Taiwan, and Singapore. Some of America’s best and brightest, including engineers at Apple, Google, and MIT, are now developing the contact-tracing technologies to safely reopen our economy and avoid future pandemic crises.

But contact tracing isn’t just a technological challenge: it’s also a cultural one. To deliver results, we’ll need the American people to set aside partisanship and anti-scientific posturing, and actually use the contact tracing technologies that we develop.

The early signs are that winning the battle for hearts and minds could be a bigger challenge than developing effective tracing technologies. In fact, surveys show that 60% of Americans currently feel that location-based tracking would make next to no difference to our fight against COVID-19.

Those numbers are disheartening. But I believe they reflect skepticism less about the efficacy of tracing technology than about the likelihood of Americans collectively embracing a technology that’s explicitly designed to collect their personal data.

Paradoxically, Americans are willing to click away their data rights if it means they can share cat photos more easily, but they’re deeply skeptical about giving people in positions of authority permission to digitally track them. They’re also skeptical about sharing potentially sensitive health information with their neighbors. That’s understandable: people quite rightly consider their health, movement, and social interactions to be private, and right now the stakes are higher than ever.

We’ve already seen ugly cases of Asian-Americans being victimized for supposedly spreading the coronavirus, and fights breaking out after people cough in public places. Now imagine the chaos that would ensue if everyone in a grocery store learned someone present had been exposed to the coronavirus — or if everyone in an apartment building discovered one of their neighbors had tested positive.

There Has to be a Better Way

For contact tracing to work at scale, we can’t dodge these critical questions of privacy, consent, and control. This isn’t an either-or situation: the idea that we can have privacy or public health, but not both, is a false choice. There has to be a better way.

Here at Ketch, we believe that tech companies need to step up and help address this thorny issue, just as they are doing in developing the core technologies that make large-scale contact tracing possible.

MIT’s Private Kit has led the way by promoting the use of Bluetooth, not GPS data, to drive contact tracing. That approach — now implemented by Apple and Google in APIs for Android and iOS devices — allows apps to focus on tracking users’ proximity to one another, rather than their specific location. Using Bluetooth, apps can identify the people you’ve had contact with, without recording more sensitive information such as whether you met them at church or at the liquor store.

Bluetooth doesn’t solve every problem: it’s easy to imagine marketers using stationary Bluetooth beacons to piggyback on contact-tracing infrastructure to track shoppers passing through their stores, for instance. But such strategies are a step in the right direction, and a sign of the kind of innovation we’ll need to build a trustworthy tracing system that respects users’ right to privacy.

To ensure contact tracing success in the U.S., we’ll need robust, verifiable, and scalable privacy protections to win the buy-in that will allow us to scale this vital technology.

Fortunately, this is a challenge the tech industry knows how to solve. In my next blog post, I’ll dig deeper, and show how we can start to build a contact tracing infrastructure that combines both effective tracking and utterly trustworthy privacy protections.
