There was a piece, I _think_ in Scientific American, tho it might have been an AI journal, on face recognition by use of neural nets together with what were called "eigenface" images: These eigenfaces each have specific characteristics, which when combined together can closely approximate a specific face image. The target face was analyzed in terms of closeness-of-match to a small set of eigenfaces, on the order of 5 to 8, I think. Results of course were promising (else why write about it, eh?) if not excellent.
You are thinking of the article in Scientific American about the Vision and Modeling group at the MIT Media Lab. For face recognition stuff, check out: http://www-white.media.mit.edu/vismod/demos/facerec/index.html Crypto and privacy relevance? Lots, I imagine. -jon
