Abstract

The invention discloses an information encryption bearing method based on magnetic domain programming, and belongs to the technical field of encrypted information carriers. The information encryptionbearing method comprises the following steps that hard magnetic particles are added into a polymer, so as to enable a sample to be deformed and display information of a to-be-encrypted load, and thenthe sample is put into a magnetic field to be magnetized to realize magnetic domain programming, so that when the loaded information is recorded in a programmed magnetic domain introduced into the sample and magnetic field excitation is applied again, the sample is automatically deformed by a mechanical load induced by the magnetic field, and the loaded information is restored in real time; and after the magnetic field disappears, the sample automatically restores to the initial shape immediately to realize bearing information hiding. According to the information encryption bearing method, a programmed magnetic domain is introduced into a sample to record bearing information; the magnetic field induced mechanical load enables the sample to deform and restore the encrypted information; theexperimental method is simple and feasible; the concept can also be applied to other types of materials and excitation modes; a new feasible rapid implementation method is provided for information transmission design and application; and the development of a novel information carrier technology is certainly promoted.

Description

technical field [0001] The invention relates to the technical field of encrypted information carriers, in particular to an information encrypted carrying method based on magnetic domain programming. Background technique [0002] Information itself is not an entity, but the content contained in messages, instructions, data and signals, which must be transmitted by some kind of medium. The evolution of information carriers drives the development of human information activities. In a sense, the signal revolution is the revolution of the information carrier. [0003] Information carrier is the medium that carries information in information dissemination, and is the material basis on which information is attached, that is, the entity used to record, transmit, accumulate and preserve information. Information carriers include intangible carriers characterized by energy and media, which use sound waves, light waves, and radio waves to transmit information, and tangible carriers th...
