METHOD OF MULTILEVEL CONTROL AND DATA INTEGRITY ASSURANCE Russian patent published in 2019 - IPC G06F11/08 G06F21/64 

FIELD: data processing.

SUBSTANCE: invention relates to methods for multilevel control and data integrity. Representing a data unit M with sub-blocks of fixed length m₁, m₂, …, m_n, to which by rules of constructing redundant codes, control subunits m_{n + 1}, …, m_{n + r}, which enables to recover data whose integrity has been violated in conditions of destructive actions of intruder and medium after detection of error by comparing values of calculated and reference systems of hash codes.

EFFECT: technical result consists in ensuring integrity of data based on sharing cryptographic methods and methods of noise-immune coding in conditions of destructive actions of intruder and medium.
