"China's new drive for repression is being underpinned by unpre-cedented advances in technology: facial and voice recognition, GPS tracking, supercomputer databases, intercepted cell phone conver-sations, the monitoring of app use, and millions of high-resolution security cameras make it nearly impossible for a Chinese citizen to hide anything from authorities. Commercial transactions, including food deliveries and online purchases, are fed into vast databases, along with everything from biometric information to social media activities to methods of birth control. Cameras (so advanced that they can locate a single person within a stadium crowd of 60,000) scan for faces and walking patterns to track each individual's movement."
That's according to "I know China evil" or is this based on anything? We know that China was playing catch-up when Snowden leaked his stuff so they might have caught up. Can you link the corresponding leaks? I'd love to read some of the Chinese ones because the most recent big things I could find were Snowden leaks.
