there was no other method than anus scan for authentication? the fingerprint was not enough? if the anus is so reliable why bother with the fingerprint at all? how about voice authentication in lieu of all that?
This comparison obviously begs the question, it it illegal to store a scan of a child's unique anal topography?
Storing the photo in a visually-renderable format is probably unacceptable. Storing hashes should work though.
