Abstract RU 2831097 C2

FIELD: encryption.

SUBSTANCE: invention relates to the field of encryption, namely to the technology of protecting seals from forgery. Method of generating an encrypted print, which comprises a graphic area and a print boundary, as well as a digital encryption area in the form of a column; includes generating an encryption code when receiving a stamping request and loading information from the stamped file into the encryption code, wherein the encryption code records the stamped information of the stamped file, the encryption code is a barcode which is encrypted twice, and secondary encryption includes the following steps: data collection, which includes obtaining pixel information on data to be encrypted; data partitioning, in which a location in the data to be encrypted is randomly selected as a partitioning point; reconnection of two code fragments, in which the position of the front data and the rear data is reversed, and the back part of the back data and the front part of the front data are connected to form secondary encrypted data.

EFFECT: improved protection against data forgery.
