The Real Threat from China Isn't "Spy Trains"

  • September 21, 2019

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.

  • June 13, 2019

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

  • January 17, 2019

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

  • November 16, 2018

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…

Censorship in the Age of Large Cloud Providers

  • June 7, 2018

Internet censors have a new strategy in their bid to block applications and websites: pressuring the large cloud providers that host them. These providers have concerns that are much broader than the targets of censorship efforts, so they have the choice of either standing up to the censors or capitulating in order to maximize their business. Today’s internet largely reflects the dominance of a handful of companies behind the cloud services, search engines and mobile platforms that underpin the technology landscape. This new centralization radically tips the balance between those who want to censor parts of the internet and those trying to evade censorship. When the profitable answer is for a software giant to acquiesce to censors’ demands, how long can internet freedom last?…

Data Protection Laws Are Shining a Needed Light on a Secretive Industry

  • June 1, 2018

When Marc Zuckerberg testified before both the House and the Senate last month, it became immediately obvious that few US lawmakers had any appetite to regulate the pervasive surveillance taking place on the internet.

Right now, the only way we can force these companies to take our privacy more seriously is through the market. But the market is broken. First, none of us do business directly with these data brokers. Equifax might have lost my personal data in 2017, but I can’t fire them because I’m not their customer or even their user. I could complain to the companies I do business with who sell my data to Equifax, but I don’t know who they are. Markets require voluntary exchange to work properly. If consumers don’t even know where these data brokers are getting their data from and what they’re doing with it, they can’t make intelligent buying choices…
