CLASSIFICATION OF DIGITAL IMAGES WATERMARK-INGALGORITHMS

Watermarking is widely applied today for copyright of digital images, which can be easily and illegally copied and spread. This paper covers the different approaches for solving the problem of image watermarking. Classification of the digital watermarking algorithms by different criteria is given, taking into ac-count that the choice of the algorithm in a concrete situation can be done.
