PROTECTIVE ENCODING OF INFORMATION CARRIERS.

The article examines a technology for the protective encoding of information carriers based on the application of a coding coating and the subsequent identification of its parameters through resonance measurement methods. The proposed technical solutions are intended for the protection of optical discs and digital external information carriers, including single-layer and multi-layer optical storage systems. Special attention is given to the principles of encoding and decoding using electromagnetic resonance spectroscopy and impedance analysis, enabling non-contact identification and verification of coding elements with high sensitivity and accuracy.

The article describes the technological features of the system, including the possibility of selective three-dimensional encoding of multilayer optical discs, real-time monitoring of information carriers within corporate security infrastructures, and the creation of mobile or stationary sensor-based analytical devices. The advantages of the proposed technology over existing protection systems are considered, including flexible coding configurations, full production-line quality control, independence from optical drive systems, compatibility with different recording formats, and the possibility of integrating the technology into complex information security systems.

Additional attention is devoted to the practical application of the technology in corporate, industrial, scientific, medical, and military environments, as well as to issues of confidentiality and protection of sensitive information. The article also outlines the physical principles underlying the resonance method and impedance spectroscopy used for the identification and analysis of coding parameters in protected information carriers.
