So to protect my privacy, I should create a algorithmic representation of my face, allowing it to be identified in other people's pictures? And my phone/wearable should broadcast this via bluetooth to every camera in my proximity.
I'm sorry, but this sounds like a huge opportunity for exploitation.
You only have to take a picture of yourself using FaceBlock. It will automatically discover Google Glass users near you and share the algorithmic representation (which is also automatically generated) with them.
It is a first step towards protecting personal privacy in public settings. We hope more projects will follow up soon.
It's an opt-in way of blurring a face. Getting an algo representation of somebody's face is easy, so broadcasting it doesn't strike me as a problem as long as that's the only data that is being sent; as opposed to also sending any kind of user id along with it.
