I think that we should hammer down some definitions before this whole thing gets out of hand. Cryptography: Building an difficult-to-unhook bra. Steganography: Building a flesh-colored bra, or one whose unhook mechanism is hidden somewhere unexpected (Man: "How the Hell...?" Woman: "It unhooks in front." Man: "Damn those steganographers.") Public-Key Cryptography: Building a bra that anyone can put on, but that only Alice can remove. Watermarking: Building a bra that stays on even after smoothing, compression, and rotation. Also, Bob should not be able to put his own bra on over Alice's and claim ownership of her body. Fingerprinting: Um, I'm probably already in trouble for the last one, so I'll just skip this. Signatures: Building a bra with a nametag ("Property of Alice, machine wash warm...") such that bras with Alice's name only fit Alice's body. Bob could in theory remove Alice's bra and replace it with his own, but there's no real reason for him to do so. All-or-Nothing Disclosure Of Secrets: Alice transforms her bra into a duffle bag, and either (a) shows Bob how to open it, or (b) shows Bob how she made it into a duffle bag. Alice repeats the procedure until Bob is satisfied (perverted freak). One-time Pad: Kleenex. NSA: An organization that wants women to go back to wearing corsets and chastity belts. Oh, and Bill Clinton gets to keep all the keys. [looks up at what's written so far and sighs] I'm so damned juvenile. I'm going to go do something more constructive and serious.
