DATA INTEGRITY MONITORING AND ENSURING METHOD Russian patent published in 2019 - IPC G06F21/64 

FIELD: information technologies.

SUBSTANCE: invention relates to the field stored in memory for storage data protection. Data integrity monitoring and ensuring method, in which by comparison of the previously calculated reference signature of the hash function from the original data block with the calculated hash function signature from the data block being checked, which sub-blocks for the data integrity ensuring in case of its violation are formed according to the rules, similar to the modular codes construction rules, which allows to recover data, that is, to ensure their integrity under conditions of the attacker deliberate actions, for the data reliability verification after their recovery, performing the hash function signature from the already recovered data block comparison with the previously calculated reference hash function signature from the original data block.

EFFECT: ensuring the data integrity with the ability of their reliability verification after recovery in case of their integrity violation under conditions of the attacker deliberate actions.
