Face Recognition System in China explained | Mass Surveillance | TechXplainer

Summary

China has implemented one of the world's most extensive facial recognition surveillance systems, known as Skynet, with around 600 million cameras planned by 2020. The system tracks citizens in real-time, identifying criminals, political dissidents, and minorities, including Uighurs, using advanced AI software. Beyond law enforcement, facial recognition is integrated into daily life, enabling features like facial payments and automated shopping, and supports the controversial social credit system that rewards or penalizes behavior. While the technology offers convenience and security, it raises significant privacy and ethical concerns, especially regarding data use, racial profiling, and government overreach.
