METHOD FOR CRYPTOGRAPHIC RECURSIVE INTEGRITY CONTROL OF A RELATIONAL DATABASE Russian patent published in 2022 - IPC G06F21/64 G06F16/20 

FIELD: information security.

SUBSTANCE: in the method for cryptographic recursive integrity control of the relational database when performing the operation of writing and editing data at t1, t2, …tn points in time a record of an array of database relations links is initially formed, on which cryptographic transformation operations are performed on subsets of keys resulting in the formation of signature values on which a concatenation operation is performed with all relations data records A₁, A₂ …A_j, after which the operation of cryptographic transformation is performed resulting in signature values, then the concatenation operation is performed with all relations data records A₁, A₂ …A_j and the signatures of the array of relation links, after which cryptographic transformation operations are performed resulting in the formation of signature values; these operations are performed similarly for all data.

EFFECT: increasing the level of data security when processing data in a database with the possibility of monitoring their integrity, detecting unauthorized modified records caused by deliberate actions of authorized users.
