According to Tony Porter, the Surveillance Camera Commissioner, CCTV is advancing to such a point that cameras capable of lip-reading could be used on city streets. He says that people will have to cover their mouths with their hands, or do something similar, to prevent surveillance operatives from understanding what they are saying.
Some technologies can identify people by the way they walk, and it is advances like this that worry many people about the oppressive potential of such technologies. How would people be effected knowing that any conversation they have on a public street may be recorded and potentially used against them in the future?
