Cryptographic protection of human images in the CCTV video stream
Many people are scared by the thought that hundreds of surveillance cameras are constantly monitoring them. But what to do is the reality of today. In fact, in the central part of modern megacities, a person does not disappear from their field of view for a second. At the same time, the police are introducing face recognition technologies and making a centralized control system for these cameras, so that they can automatically “transmit” the object of observation to each other, for hours tracking the movement of a certain person in the city.
How to prevent the creation of a police state with such a development of technology? This seems to be impossible. However, the wedge is kicked out by wedge. I mean, we can use other technologies to protect against technology.
For example, 3VR, which is developing global video surveillance systems for cities, is trying to present the privacy feature as a competitive advantage for its commercial products. They introduced the technology of cryptographic protection of the video stream, where the images of people are encrypted with secret keys and visually turn into unrecognizable masks, as in the photo above. Each person has his own individual mask, because the system first recognizes faces, and then assigns each a separate key.
The key to "decrypt" a particular person is only given to the competent authorities if necessary. Thus, the police can track specific suspects, but the rest of the people in the frame remain “invisible”.
