Abstract

The invention relates to the computer and electronic technique and may be used in image recognition systems for the secret marking the information on arbitrary articles, e.g. securities, bank notes, plastic cards etc., in the form of various configuration codes, which allows to reduce the probability of the unauthorized reproducing and reading. The proposed method for writing and reading of inforamtion possesses the high reliability of the encoded information writing due to the use of a new information carrier, the ultrathin magnetic film having a thickness less than 50 Å and protected with an optically opaque cover, which completely excludes the possibility of the forgery without knowledge of the manufacturing condition, the ultrathin magnetic film material, the writing information location, and also allows to store the 'magnetic' information after an arbitrary magnetic force action, i.e. an equivalent of the read only memory; and to identify the encoded information authenticity by the magnetic field configuration and amplitude. A sensing element of the scanning SQUID magnetometer is used for the information reading, which is the quantum interferometer made of a high-temperature superconducting material.
