WATERMARK EMBEDDING INTO AN IMAGE WITH THE HELP OF OPTIMIZING METHOD OF CUCKOO SEARCHING

The algorithm that has been developed on base of the proposed in 2015 by Iraq and Chinese researches method of image watermarking is presented in this work. In the proposed digital watermarking algorithm the discrete wavelet transform and the method of cuckoo searching are used which allow to optimize positions of watermark embedding into an image. The program has been developed realizing the algorithm. Research of the developed algorithm is produced on stability to different attacks that an image can undergo. The results of ex-perimental researches are presented.
