anyone can help me, I'm working on watermarking application for mp3 files with algorithms "echo data hiding". I do not understand to make this algorithm with java or matlab. I hope anyone can help by explaining this algorithm, or give examples with source code.

thank you

Maybe this paper brings some light in the darkness: Watermarking

  • thanks for the answer, but I am still confused with echo hiding algorithm, the paper's not too clear echo hiding method in particular, only provide an explanation in general terms. – user494485 Nov 02 '10 at 14:59

Binary Universe gives an overview of stenography in general and has a section on audio, although it doesn't deal with mp3. I'm not sure how feasible stenography is for a lossy format such as mp3. I assume you would have to add it after the compression has taken place.

  • at the site, explains the working process of the LSB algorithm is not echo hiding. echo hiding if I am not mistaken, using the signal from the mp3 file that will be in the watermark. I do not know how to process the signal in java to create algorithms echo hiding. – user494485 Nov 02 '10 at 15:03
