Alibaba, ByteDance share algorithm details with Chinese regulator

Chinese tech giants including Alibaba, Tencent and ByteDance have submitted details to a state regulator of algorithms used in some of their products, in an unprecedented move as authorities strengthen oversight of the sector.

The country’s internet watchdog on Friday published a list of 30 algorithms that companies use to gather information on users and promote content or services.

Algorithms used by tech companies are closely guarded globally but in March, China rolled out regulations obliging firms to disclose these tools as concerns grow about data misuse.
