Using online profile and movements, government aims to catch "terrorists" in advance.

China is building a big data platform for “precrime”

It's "precrime" meets "thoughtcrime." China is using its substantial surveillance apparatus as the basis for a "unified information environment" that will allow authorities to profile individual citizens based upon their online behaviors, financial transactions, where they go, and who they see. The authorities are watching for deviations from the norm that might indicate someone is involved in suspicious activity. And they're doing it with a hand from technology pioneered in the US.

As Defense One's Patrick Tucker reports, the Chinese government is leveraging "predictive policing" capabilities that have been used by US law enforcement, and it has funded research into machine learning and other artificial intelligence technologies to identify human faces in surveillance video. The Chinese government has also used this technology to create a "Situation-Aware Public Security Evaluation (SAPE) platform" that predicts "security events" based on surveillance data, which includes anything from actual terrorist attacks to large gatherings of people.

The Chinese government has plenty of data to feed into such systems. China invested heavily in building its surveillance capabilities in major cities over the past five years, with spending on "domestic security and stability" surpassing China's defense budget—and turning the country into the biggest market for security technology. And in December, China's government gained a new tool in surveillance: anti-terrorism laws giving the government even more surveillance powers and requiring any technology companies doing business in China to provide assistance in that surveillance.

The law states that companies “shall provide technical interfaces, decryption and other technical support and assistance to public security and state security agencies when they are following the law to avert and investigate terrorist activities”—in other words, the sort of "golden key" that FBI Director James Comey has lobbied for in the US. For obvious reasons, the Chinese government is particularly interested in the outcome of the current legal confrontation between the FBI and Apple over the iPhone used by Syed Farook.

Bloomberg reports that China is harnessing all that data in an effort to perform behavioral prediction at an individual level—tasking the state-owned defense contractor China Electronics Technology Group to develop software that can sift through the online activities, financial transactions, work data, and other behavioral data of citizens to predict which will perform "terrorist" acts. The system could watch for unexpected transfers of money, calls overseas by individuals with no relatives outside the country, and other trigger events that might indicate they were plotting an illegal action. China's definition of "terrorism" is more expansive than that of many countries.

At a news conference in December, China Electronics Technology Group Chief Engineer Wu Manqing told reporters, "We don’t call it a big data platform, but a united information environment… It’s very crucial to examine the cause after an act of terror, but what is more important is to predict the upcoming activities.”
