Digital watermarking is the way to solve digital image copyright protection problem. Such a solution is quite new and the need for software, which would ensure image authentication, is huge. Image authentication control area and its relevance are analyzed in this work. Digital watermarking theoretical basics are presented; six algorithms – Cox, Kim, Wang, Xia, Dugad and Zhu – are analyzed. The analysis of similar software was performed; it revealed the predominance of such software products that allows only visible (though transparent) watermarking, and the number of software with a possibility of invisible watermarking is small. The work consists of these main parts: analysis, design, user documentation and experimental research. The main objective of this work was to design and implement image authentication control system. This system has such features: PGM and JPEG format images review, digital watermark generation, embedding, extraction.
