Face-Swapping Software To Protect Privacy

(0d0 writes "Some researchers at Columbia University's Computer Vision Labratory have developed software to automatically replace faces in batches of photos. Practical applications include protecting the identities of people in Google's Street View, coupling it with a digital camera's burst mode to create a perfect group photo, or protecting the identities of witnesses or law enforcement and military personnel. Other links to coverage include Boing Boing, American Public Media, and New Scientist."

Google StreetView does this already

Unfortunately, I don't have any links saved, but I have seen several instances on Google Street View where faces have been blurred far beyond recognition, as well as license plates.

The group photo thing sounds cool. Microsoft has a Research app called Group Shot that can stitch numerous photos together to make a group shot. The problem is, people aren't statues, and the movement of bodies becomes very obvious when a part of someones shoulder is 3 inches higher than the part next to it. I'd gladly pay for a consumer ready adaptation of this technology.

on the other hand

what if I want my photo on google? what if I don't want to be defaced? and find it insulting? can I sue for posting an altered image of myself online? what if I have a picture of my face on my t-shirt?

I've seen cases where a car's hubcaps were blurred, presumably because the face-search-and-blur algorithm hit it. Here is one example [google.com] (for street view of 116 Manhattan Ave, Jersey City, NJ, in case the link isn't right). It would be interesting to see what the face swapping software does when one of the faces is a hubcap or other inanimate object. The other question is how reversible is the face swapping techonolgy? Given the altered photo and one of the two originals, can the 2nd original be reconstructed?
