China’s evolving algorithmic surveillance system will rely on the security organs of the communist party-state to filter, collect, and analyze staggering volumes of data flowing across the internet. Justifying controls in the name of national security and social stability, China originally planned to develop what it called a “Golden Shield” surveillance system allowing easy access to local, national, and regional records on each citizen. This ambitious project has so far been mostly confined to a content-filtering Great Firewall, which prohibits foreign internet sites including Google, Facebook, and The New York Times. According to Freedom House, China’s level of internet freedom is already the worst on the planet. Now, the Communist Party of China is finally building the extensive, multilevel data-gathering system it has dreamed of for decades.

While the Chinese government has long scrutinized individual citizens for evidence of disloyalty to the regime, only now is it beginning to develop comprehensive, constantly updated, and granular records on each citizen’s political persuasions, comments, associations, and even consumer habits. The new social credit system under development will consolidate reams of records from private companies and government bureaucracies into a single “citizen score” for each Chinese citizen. In its comprehensive 2014 planning outline, the CCP explains a goal of “keep[ing] trust and constraints against breaking trust.” While the system is voluntary for now, it will be mandatory by 2020. Already, 100,000 Chinese citizens have posted on social media about high scores on a “Sesame Credit” app operated by Alibaba, in a private-sector precursor to the proposed government system. The massive e-commerce conglomerate claims its app is only tracking users’ financial and credit behavior, but promises to offer a “holistic rating of character.” It is not hard to imagine many Chinese boasting soon about their official scores.

While it isn’t yet clear what data will be considered, commentators are already speculating that the scope of the system will be alarmingly wide. The planned “citizen credit” score will likely weigh far more data than the Western FICO score, which helps lenders make fast and reliable decisions on whether to extend financial credit. While the latter simply tracks whether you’ve paid back your debts and managed your money well, experts on China and internet privacy have speculated—based on the vast amounts of online shopping data mined by the government without regard for consumer privacy—that your Chinese credit score could be higher if you buy items the regime likes—like diapers—and lower if you buy ones it doesn’t, like video games or alcohol. Well beyond the realm of online consumer purchasing, your political involvement could also heavily affect your score: Posting political opinions without prior permission or even posting true news that the Chinese government dislikes could decrease your rank.
