1. A method comprising:
- receiving user input corresponding to compression;
using a programmed electronic processor, embedding a digital watermark in content;
compressing the digital watermarked content with reference to at least the user input;
decompressing the compressed, digital watermarked content;
analyzing the decompressed digital watermarked content; and
based at least in part on said act of analyzing, determining whether to again embed the digital watermark in the content under different embedding conditions.
