METHOD FOR MESSAGE INTEGRATION INTO DIGITAL IMAGE Russian patent published in 2010 - IPC H04N7/08 H04L9/00 

FIELD: information technologies.

SUBSTANCE: method is based on series of information bits match with bits in bytes of colour presentation, with change of least significant bits in initial image and requiring minimum correction of statistical characteristics of only least significant bits, as a result of accidental nature of matches. Least significant bit is replaced in bytes in initial digital image, besides, flag value "one" is assigned to least significant bit in bytes of initial digital image, if part of digital image signal byte bits and message signal bits match, or flag value "zero" is assigned in case of non-match, at the same time correction of statistics of distribution of least significant bits is made by their remaining part, which is not used as flag values.

EFFECT: possibility to store and transfer large volumes of confidential information.
