Since all the scandals about security, I came up with a different approach, instead to increase cryptography, just build kind of a reverse surveillance. A place like gravatar that informs you who is accessing to your profiles on your social media. The idea is very simple, you provide a jpg that can send back a message every time it's being rendered by a client. It can be that it requires a new image standard that allows to send some info to the main servers.
