The main task of this work is to present a novel algorithm for block embedding of information into digital images frequency domain designed to ensure confidentiality of the information. This paper contents different methods of embedding of information into digital images frequency domain including ternary embedding primitive, quantization index modulation and adaptive embedding. It is examined which methods contribute to the imperceptibility of the embedded information the most. Finally, those methods are being implemented and tested using computing environment Matlab. Created algorithms can be used in steganography to conceal transmission or storage of confidential information. There are 53 pages, including 10 illustrations, 9 tables, 36 sources and 1 attachment.
