Abstract: A hard/software system for applying and reading out an information field identifying and protecting an item, comprises an applying unit, a reading unit, a control unit, and a database unit. The applying unit (for example, a laser or printer) generates the information field and transports it to the item. The control unit comprises an information field data encryption module, a random number generator key, a controlling script configuration module to interact with the applying unit, and a reading and image acquiring module, and a decryption and information output module to interact with the reading unit. The database unit comprises an information field applying unit module, an item material properties module, and an item processing technological mode module for applying the information field. The reading unit can include a digital microscope. The system can apply the information field on various materials, the shape of the item can be plain, cylindrical, etc.

Abstract: The method provides encoding digital information by assigning encoding values from a plurality of collectives of encoding values to the message symbols. The collectives are unbound from each other, are selected randomly, and setting a correspondence between the symbols and encoding values of the selected collectives is random. Elements of the encoded message can be further assigned encoding values of further selected collectives. The method can be implemented both in virtual form using Cloud Computing technology and in a physical form, where encryption and decryption blocks are implemented in one environment physically protected against unauthorized access, writing and copying. Performing encoding and decoding in a user-inaccessible environment and providing the user only with the results of encoding and decoding processes prevents unauthorized access thereto from occurring. The technical result is widening the field of use, improved reliability and security of the digital and analog information.

Abstract: A method of marking an object for identification purposes uses a local heating source, preferably a solid-state or fiber laser, to form a multi-symbol encoded encrypted monochrome or polychrome message with identification parameters of the object by impacting its surface. The message is created by modifying optical properties and structural configuration of the surface to create contrast microscopic imprints comprising cluster nanostructures of elements of the material of the surface. Encoding the message is based on a primary code array of correspondence of each of the message symbols to a multibit combination of 0 and 1 respectively representing absence and presence of the heating source impact imprint. Encrypting is effected by creating particular code arrays based on the primary one by means of random perturbation of its components. The invention makes it practically impossible to counterfeit the objects, replace them, or make a subject of others illegal actions.
