How the Golden Shield Works

by Marshall Brain

China is in the process of building the world’s largest security system called the Golden Shield:

China’s All-Seeing Eye

The story focuses on the city of Shenzhen and describes it this way:

Shenzhen is a city of 12.4 million people, and there is a good chance that at least half of everything you own was made here: iPods, laptops, sneakers, flatscreen TVs, cellphones, jeans, maybe your desk chair, possibly your car and almost certainly your printer. Hundreds of luxury condominiums tower over the city; many are more than 40 stories high, topped with three-story penthouses.

The city is also home to a surge in security cameras:

Over the next three years, Chinese security executives predict they will install as many as 2 million CCTVs in Shenzhen, which would make it the most watched city in the world. (Security-crazy London boasts only half a million surveillance cameras.)

Those cameras, along with several other technologies, will hook together to create the Golden Shield:

This is how this Golden Shield will work: Chinese citizens will be watched around the clock through networked CCTV cameras and remote monitoring of computers. They will be listened to on their phone calls, monitored by digital voice-recognition technologies. Their Internet access will be aggressively limited through the country’s notorious system of online controls known as the “Great Firewall.” Their movements will be tracked through national ID cards with scannable computer chips and photos that are instantly uploaded to police databases and linked to their holder’s personal data. This is the most important element of all: linking all these tools together in a massive, searchable database of names, photos, residency information, work history and biometric data. When Golden Shield is finished, there will be a photo in those databases for every person in China: 1.3 billion faces.

Shenzhen is the place where the shield has received its most extensive fortifications — the place where all the spy toys are being hooked together and tested to see what they can do. “The central government eventually wants to have city-by-city surveillance, so they could just sit and monitor one city and its surveillance system as a whole,” Zhang says. “It’s all part of that bigger project. Once the tests are done and it’s proven, they will be spreading from the big province to the cities, even to the rural farmland.”

The effect is all encompassing:

Up in my room, the Website that pops up on my laptop looks like every other Net portal at a hotel — only it won’t let me access human-rights and labor Websites that I know are working fine. The TV gets CNN International — only with strange edits and obviously censored blackouts. My cellphone picks up a strong signal for the China Mobile network. A few months earlier, in Davos, Switzerland, the CEO of China Mobile bragged to a crowd of communications executives that “we not only know who you are, we also know where you are.” Asked about customer privacy, he replied that his company only gives “this kind of data to government authorities” — pretty much the same answer I got from the clerk at the front desk.

When I leave China, I feel a powerful relief: I have escaped. I am home safe. But the feeling starts to fade as soon as I get to the customs line at JFK, watching hundreds of visitors line up to have their pictures taken and fingers scanned. In the terminal, someone hands me a brochure for “Fly Clear.” All I need to do is have my fingerprints and irises scanned, and I can get a Clear card with a biometric chip that will let me sail through security. Later, I look it up: The company providing the technology is L-1.
