Abstract
Various improvements to steganographic systems, and applications therefore, are disclosed. Among these are analyzing content data (e.g., audio, image data) in a computer memory automatically, without user intervention, so as to detect steganographically embedded information. The results of such analysis can be used to alter an aspect of the computer device'"'"'s operation with respect to such content data. One application of the technology is to check the “clipboard” of a computer and alert the user when copyrighted material is found therein.
