Abstract

[English abstract]
Digital watermark is a pattern of bits inserted into an image, audio or video
file, which contains information related to this file. The purpose of digital
watermark is to provide copyright protection for intellectual property that
is in digital format. Invisible digital watermark attracts greater attention
than visible. It is not a simple task to make a good watermark. It must be
imperceptible for the human observer; on the other hand, it must be robust
against usual operations (change of brightness and contrast, cropping
rotation, lossy compression.) and against malicious attacks
