The Public Good Requires Private Data
This essay appeared as part of a round table on “How the Coronavirus Pandemic Will Permanently Expand Government Powers.”
There’s been a fundamental battle in Western societies about the use of personal data, one that pits the individual’s right to privacy against the value of that data to all of us collectively. Until now, most of that discussion has focused on surveillance capitalism. For example, Google Maps shows us real-time traffic, but it does so by collecting location data from everyone using the service.
COVID-19 adds a new urgency to the debate and brings in new actors such as public health authorities and the medical sector. It’s not just about smartphone apps tracing contacts with infected people that are currently being rolled out by corporations and governments around the world. The medical community will seize the pandemic to boost its case for accessing detailed health data to perform all sorts of research studies. Public health authorities will push for more surveillance in order to get early warning of future pandemics. It’s the same trade-off. Individually, the data is very intimate. But collectively, it has enormous value to us all…
We’re Banning Facial Recognition. We’re Missing the Point.
The whole point of modern surveillance is to treat people differently, and facial recognition technologies are only a small part of that.
Communities across the United States are starting to ban facial recognition technologies. In May of last year, San Francisco banned facial recognition; the neighboring city of Oakland soon followed, as did Somerville and Brookline in Massachusetts (a statewide ban may follow). In December, San Diego suspended a facial recognition program in advance of a new statewide law, which declared it illegal, coming into effect. Forty major music festivals pledged not to use the technology, and activists are calling for a nationwide ban. Many Democratic presidential candidates …
The Real Threat from China Isn't "Spy Trains"
The trade war with China has reached a new industry: subway cars. Congress is considering legislation that would prevent the world’s largest train maker, the Chinese-owned CRRC Corporation, from competing on new contracts in the United States.
Part of the reasoning behind this legislation is economic, and stems from worries about Chinese industries undercutting the competition and dominating key global industries. But another part involves fears about national security. News articles talk about “spy trains,” and the possibility that the train cars might surreptitiously monitor their passengers’ faces, movements, conversations or phone calls…
The Myth of Consumer Security
The Department of Justice wants access to encrypted consumer devices but promises not to infiltrate business products or affect critical infrastructure. Yet that’s not possible, because there is no longer any difference between those categories of devices. Consumer devices are critical infrastructure. They affect national security. And it would be foolish to weaken them, even at the request of law enforcement.
In his keynote address at the International Conference on Cybersecurity, Attorney General William Barr argued that companies should weaken encryption systems to gain access to consumer devices for criminal investigations. Barr repeated a common fallacy about a difference between military-grade encryption and consumer encryption: “After all, we are not talking about protecting the nation’s nuclear launch codes. Nor are we necessarily talking about the customized encryption used by large business enterprises to protect their operations. We are talking about consumer products and services such as messaging, smart phones, e-mail, and voice and data applications.”…
Attorney General William Barr on Encryption Policy
This morning, Attorney General William Barr gave a major speech on encryption policy—what is commonly known as “going dark.” Speaking at Fordham University in New York, he admitted that adding backdoors decreases security but that it is worth it.
Some hold this view dogmatically, claiming that it is technologically impossible to provide lawful access without weakening security against unlawful access. But, in the world of cybersecurity, we do not deal in absolute guarantees but in relative risks. All systems fall short of optimality and have some residual risk of vulnerability—a point which the tech community acknowledges when they propose that law enforcement can satisfy its requirements by exploiting vulnerabilities in their products. The real question is whether the residual risk of vulnerability resulting from incorporating a lawful access mechanism is materially greater than those already in the unmodified product. The Department does not believe this can be demonstrated…
AI Has Made Video Surveillance Automated and Terrifying
AI can flag people based on their clothing or behavior, identify people's emotions, and find people who are acting "unusual."
It used to be that surveillance cameras were passive. Maybe they just recorded, and no one looked at the video unless they needed to. Maybe a bored guard watched a dozen different screens, scanning for something interesting. In either case, the video was only stored for a few days because storage was expensive.
Increasingly, none of that is true. Recent developments in video analytics—fueled by artificial intelligence techniques like machine learning—enable computers to watch and understand surveillance videos with human-like discernment. Identification technologies make it easier to automatically figure out who is in the videos. And finally, the cameras themselves have become cheaper, more ubiquitous, and much better; cameras mounted on drones can effectively watch an entire city. Computers can watch all the video without human issues like distraction, fatigue, training, or needing to be paid. The result is a level of surveillance that was impossible just a few years ago…
AI Can Thrive in Open Societies
The belief that China’s surveillance gives it an advantage is misleading—and dangerous.
According to foreign-policy experts and the defense establishment, the United States is caught in an artificial intelligence arms race with China—one with serious implications for national security. The conventional version of this story suggests that the United States is at a disadvantage because of self-imposed restraints on the collection of data and the privacy of its citizens, while China, an unrestrained surveillance state, is at an advantage. In this vision, the data that China collects will be fed into its systems, leading to more powerful AI with capabilities we can only imagine today. Since Western countries can’t or won’t reap such a comprehensive harvest of data from their citizens, China will win the …
A New Privacy Constitution for Facebook
Mark Zuckerberg wants to fix the social network. Here’s what he’ll need to do.
Facebook is making a new and stronger commitment to privacy. Last month, the company hired three of its most vociferous critics and installed them in senior technical positions. And on Wednesday, Mark Zuckerberg wrote that the company will pivot to focus on private conversations over the public sharing that has long defined the platform, even while conceding that “frankly we don’t currently have a strong reputation for building privacy protective services.”
There is ample reason to question Zuckerberg’s pronouncement: The company has made—and broken…
Evaluating the GCHQ Exceptional Access Proposal
The so-called Crypto Wars have been going on for 25 years now. Basically, the FBI—and some of their peer agencies in the U.K., Australia, and elsewhere—argue that the pervasive use of civilian encryption is hampering their ability to solve crimes and that they need the tech companies to make their systems susceptible to government eavesdroping. Sometimes their complaint is about communications systems, like voice or messaging apps. Sometimes it’s about end-user devices. On the other side of this debate is pretty much all technologists working in computer security and cryptography, who …
Surveillance Kills Freedom By Killing Experimentation
Excerpted from the upcoming issue of McSweeney’s, “The End of Trust,” a collection featuring more than 30 writers investigating surveillance, technology, and privacy.
In my book Data and Goliath, I write about the value of privacy. I talk about how it is essential for political liberty and justice, and for commercial fairness and equality. I talk about how it increases personal freedom and individual autonomy, and how the lack of it makes us all less secure. But this is probably the most important argument as to why society as a whole must protect privacy: it allows society to progress…
