Re: [WM]: Another use for steganography

[Ron van Schyndel <ronvs@cs.rmit.edu.au>]

A better option would be a pseudo-noise based WM in the microphone.  The subject will not know that the continuity WM is inserted.
The PN noise can be made to sound like analog tape hiss, and the level control can be automatic based on content.  The WM key alters
each cycle to the next key based on another separate PN sequence, whose initial seed is the password.  Continuity is then assured,
but not content.  Make the WM key also content dependent and you have it all.

If the microphone is through a notebook computer, then a program can build/insert the WM.

Warning: standard disclaimers about the use of PN sequence apply here.
