COMPACT HARDWARE ELECTRONIC MEDIA OF INFORMATION WITH MULTI-LEVEL REGULATION OF ACCESS TO SEPARATE MEMORY SECTIONS Russian patent published in 2017 - IPC G06F21/62 

FIELD: information technology.

SUBSTANCE: medium contains nonvolatile memory (NVM) divided into several separate areas, in which information is located with different degrees of protection. Access to each of these areas of memory is regulated by the EM processor separately. The processor controlling access to the NVP controls access to each of the NVP areas by concurrently having a positive result of, at least, one authentication of each of the EM end user and the user computing device, to which the electronic medium is connected. And the EM contains a means for additional authentication of the user when accessing separate areas of the device memory and a cryptographic protection processor for cryptographic information, for controlling access to the functions of which the processor that manages access to the NVP is intended. The processor controlling access to the NVP is configured to obtain the results of additional user authentication from the additional identification means and to provide access only to a portion of the NVP, externally indistinguishably simulating the work with the entire EM memory, with a negative result of additional authentication indicating that the user is operating under an external coercion or control.

EFFECT: increasing the level of the access control security.
