1. A method comprising:
- receiving packaged content over a network as a result of a negotiated transaction involving payment by a user, the content being packaged with at least encryption;
unpackaging the content for rendering to the user, but prior to rendering, embedding a digital watermarking in the unpackaged content, the digital watermarking including auxiliary information, the auxiliary information comprising a first portion associated with permissible uses of the content and a second portion including information generated upon unpackaging the content, and the digital watermarking carrying the auxiliary information in the unpackaged content through alterations to data representing the content; and
rendering the embedded content to the user.

Abstract
The present invention relates generally to digital watermarking and steganographic data hiding. In one embodiment a method of rendering content to a user is provided. The rendered content includes a digital watermark embedded therein. In another embodiment, digital watermarking is utilized to facilitate purchase or lease of audio or video content over a network or with a remote computer. In still another embodiment, a compression characteristic is determined, and subsequent steganographic embedding is influenced based on the characteristic. Other embodiments are provided as well.
