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.
