2. Using a watermark that will survive mp3 [F1]
not mp3 but AAC in Apple's QuickTime container format with DRM (m4p). And as far as I know (which is not very far anyways), they are the only large music site that uses AAC. This paper [1] explains how you can embed strong watermarks even in the decompressed audio data. Excerpt: --- This paper discusses the embedding of robust watermarks directly into MPEG-2 AAC bit streams such that the watermark can be detected in the decompressed audio data. --- And these slides [2] describes a two-dimensional watermarking scheme that leads 50-100% detection after AAC recompression.
