Abstract
Various improvements to digital watermarking are disclosed. For example, a digitally watermarked object can steganographically convey a payload that includes computer instructions (e.g., JAVA, ActiveX, or HTML) that--when decoded--control some manner of operation of an associated instruction processor. One application is a digital movie that, when double-clicked, automatically executes a watermark-embedded Java applet which links through a browser to the movie's distributor. The user is then prompted to input a credit card number. After the number has been verified and a charge made, the applet releases the content of the file to the computer's viewer for viewing of the movie.
