But with all that, you would need cooperation by both Google and Facebook for the feature and it would be just as complex as simply using OAuth.

  It would work on any service that allows you to share an image with one individual user.

    The service would need to send out the Cross Origin Resource Sharing headers in order for the image to be accessible via <canvas> and the service also needs a means for the querying server to test if a certain image is indeed the one associated with the user. And if it was an image generated by Facebook, then Facebook must have access to the account beforehand, and there's no benefit to using this system over OAuth.
