When CCTV can recognise you
Today we are concerned in some ways by the thought that CCTV can capture our actions and the issues about our privacy. This is balanced with the comfort that so are others and those who have nothing to hide are safe. Data (video) is kept in the promise that at some point it could be used to protect you, and conversely used to capture you, when the algorithms become sufficiently good to interrupt actions, I hope never intent.
Today, in the most part, the CCTV system cannot link the image of you to an identity of you. When this link is established could it be used to make your personal data more secure? If you lost your phone, image the local CCTV network acknowledging that it is not you holding your phone and locks the device up, or indeed starts to track it.
Would such data (systems linking images to identity) be of use, or are the benefits outweighed by the possible downsides?
