Abstract [en]

In this paper we use watermarking to embed a certain message into a digital image, We present, test, and compare four message coding algorithms. These algorithms are based on repetition coding, BCH coding, a combination of these two, and erasure-correcting coding. We consider three criteria, robustness,  number of changed pixels, and complexity, in comparing our algorithms. We will show that the way of encoding the embedded message can affect the robustness of the watermark while using the same watermarking technique.
