FIELD: information storage media. SUBSTANCE: device is designed as multilayer structure which contains graphical and alphanumeric information and is made from thin-film material, which has at least one layer with identification region, which is split into segments which are transparent modulated light flow. Goal of invention is achieved by splitting segments of identification region by means of boundary stripes, which are either continuous or discrete, are arranged over complete layer height or its part, and are made from material, which is not transparent to light. EFFECT: improved visual protection, increased number of object to be protected against unauthorized copying and faking. 12 cl, 8 dwg
