Abstract :
In this work, we investigate the interplay between compression algorithms and watermark embedding techniques. Three different image codecs are applied to a test image watermarked by three distinct watermarking techniques. We find that a match or similarity between the compression and watermarking domain or technique does not result in the best results in any case. On the contrary, the results of compression attacks of this type are extremely hard to predict
