China’s Camera Surveillance Network and Facial Recognition Technology / Alabama’s Election Result 00:59:00 2017-12-14
On Thursday's Backchat - China has been installing what's described as "the world's biggest camera surveillance network", backed by artificial intelligence and facial recognition technology. Already 170 million CCTV cameras have been set up across the country, and 400 million more are to be added by 2020. It means the authorities will have the ability to track the movements and contacts of every citizen - continuously. While this may have benefits for law enforcement and catching criminals, civil rights advocates fear it way also be used to target dissent. And while China may be a special case, there are implications globally. And it's not just CCTV networks: there are many ways that our movements, our viewing habits, our spending patters and other aspects of our lifestyles can be monitored and recorded. Should we be worried?  What can we do about it? Is AI leading us into a brave new world?  Tell us what you think. Leave us a comment, or email us at, or give us a call on 23388266. After 9.20, an upset in US politics, with the Democrats taking Alabama.
