METHOD OF UNCORRECTED INFORMATION RECORDING Russian patent published in 2020 - IPC G06F12/16 

FIELD: information security.

SUBSTANCE: invention relates to information security components and methods of uncorrectable information recording. Recording system comprises main memory (ROM), a general-purpose processor (CPU) and a trusted (secure) microcontroller with cryptographic functional (SCF) and protected memory, cryptographic key carriers (KC) of initiating information exchange, chain record technology during information recording and interactive formation of common signature of registration device and one or more subjects. Uncorrectable registration of information with subsequent confirmation of authenticity of registration device and information exchange subjects, as well as with guarantee of non-repudiation is provided by the fact that registration device sends registered information in SCF; SCF calculates the footprint based on the transmitted data and the value stored in its memory and stores the obtained value; SCF and KC of information exchange subjects jointly and interactively calculate signature , which is stored in main memory of registration device together with identifiers or public keys of current subjects, information and its imprint .

EFFECT: technical result is providing integrity of registered information.
