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 will automatically discover Google Glass users near you.

Assuming, the Google glass's bluetooth is ON (discoverable). Otherwise it won't work. Right?

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.

How creepy would it be if everyone changed their social media avatars to be their eigenface ... I'mma do that for Halloween!

Awesome job guys!!
