While we are very good at recognizing somebody we know on a picture, it is in fact very hard to answer the following question: is the person in front of you is the same person who is depicted on the photo? AFAIR there were experiments which show that if you just get a random photo of a person with the same race, age, and gender as you have you have very good probability to successfully pretend that you are the person on the picture. As a result the criminal don't really need to change the photo to be able to pretend that he is you. -- Regards, ASK --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
