The paper focuses on the steganographic method that carries out simultaneous
effective solution for creation of covert communication channel within the channel for public
use, check of the integrity and authenticity of the transmitted additional information. These
tasks define the so-called three-pronged task (TT) that is of current interest, but today,
according to the data available from the open press, has no satisfactory solution. This is
connected with the complexity of TT and moreover a covert communication channel itself
requires additional guaranteeing the reliability of perception and insensitivity of formed
steganomessage against disturbing influences. The digital image stands as a container. The
additional embedded information that is the result of pre-primary encoding of confidential
information and the subsequent secondary coding using a secret key for authentication is
represented as a binary sequence. Developed steganomethod for solving TT, ensures the
reliability of perception of formed steganomessage, is resistant to attacks against embedded
messages and allows to effectively decode the transmitted information even in the event of a
breach of its integrity, that is evidenced by the results of a computational experiment. |
