Annotation: Information and analytical systems are considered, the functioning of which is based on the processing of multidimensional arrays of information in the conditions of destructive effects of an attacker and environmental disturbances. A subsystem of data integrity control is proposed, based on the use of redundant coding, in which the data to be protected is presented in the form of blocks, pre-grouped according to the criterion of "information value" to ensure the correctness of the user's decision-making of an information and analytical system.
Keywords: information protection, data integrity control, codes with unequal character protection
