    Results of the encryption methods analysis showed, that modern approaches only consider the cryptographic and steganographic properties of data protection algorithms and do not provide the proper level of information confidentiality. An advanced data encryption method based on a monochrome image alphabet, which takes into account cryptographic and steganographic properties of information security, has been proposed in the article. The method utilizes mathematical techniques to conceal the content of the original message, specifically by transforming its characters into an alphabet-like form and applying mathematical operations to convert the result into ciphertext. In combination with steganographic techniques, a monochrome image serves as the container, forming the basis for constructing a pixel matrix. It is shown that the cryptographic resilience of the method and information confidence exhibit functional dependency on the number of blocks into which the original image is divided, as well as its key system and the dynamic nature of pixel alphabet formation. The results of the experiment confirm that the method possesses the combination of cryptographic and steganographic properties exhibits, high efficiency, and provides an adequate and necessary level of information confidentiality. The conducted experiments have confirmed the functionality and adequacy of the proposed data encryption method based on a monochrome image alphabet. This allows us to recommend its practical use for information protection systems in institutions and organizations.
