Abstract:
In this paper we proposed a universal method for forming the watermark for both physical and electronic documents. Such a watermark can be used for authentication of documents, as well as for secure communication. For both cases we described the procedure for exchange of information between two parties. The analysis of the complexity of detecting the presence of the watermark and extracting the embedded information by a third party was performed, and it showed operability of the proposed method.
Keywords:actual physical document, the authenticity of electronic documents, steganography, stegosystem, stegokonteyner, digital watermark (DW), a cliche, the pixel representation of the image.
