METHOD FOR SETTING LABELS AND IDENTIFICATION OF INFORMATION CARRIERS Russian patent published in 1996 - IPC

Abstract RU 2054711 C1

FIELD: computer engineering. SUBSTANCE: method involves generation of label, which conforms to encoded electromagnetic characteristics. This is achieved by content of information carrier which contains gyromagnetic particles with crystal anisotropy. Code electromagnetic characteristics of label is its frequency response. In order to achieve required level of frequency response, label is identified by frequency distribution of natural magnetic resonance of particles. EFFECT: increased efficiency of protection against destruction and forgery. 3 cl, 4 dwg
