FIELD: magnetic cryptography.
SUBSTANCE: invention relates to magnetic cryptography. The essence of the invention lies in the fact that the target digital information is applied to the cryptographic carrier and the decryption of this information is performed, the cryptographic carrier is a binary magnetic cryptogram, which is formed by magnetic recording using a magnetic pixel method for encrypted target information on the initial blank, made in the form of a flat plate of non-magnetic material equipped with discrete magnetic elements with high coercive ability, and to decrypt the target information, a matrix magnetic scanner is used.
EFFECT: providing the possibility of unambiguous reading and interpretation of information previously recorded and encrypted on a thin-film or plate blank covered with a thin-layer magnetically sensitive layer.
