The data embedding method based on the secret sharing scheme

Important characteristics of stegosystems are the relative length $\alpha$ of the message to be inserted and the relative effectiveness of the embedding $e$. Additional essential characteristics of such systems are the degree of freedom in choosing modifiable bits of the container and the ability to resist loss of part of the stegocontainer blocks. This paper is devoted to the development of the stegosystem which, on the one hand, allows recovering partially lost data and, on the other hand, gives the opportunity to choose modifiable bits. On the basis of this system, stegosystems are constructed and investigated, for which the characteristics of $\alpha$ and $e$ are calculated and the degree of freedom and the number of erasures of blocks that do not distort the disseminated data are estimated.
