Summary:FIELD: technologies for protecting valuable products from forgery. ^ SUBSTANCE: passive protective means is formed on product, having given structure, which makes it possible to control presence and authenticity of aforementioned means by physical analysis method by resonance effect in process of external influence on it by probing electromagnetic radiation of given radio frequency and detecting parameters of certain informative signs in resonance response of protective device for aforementioned external influence with following automatic comparison of registered parameters of these informative signs with standard values. As passive protective means, metallized, at least, three-layered resonance filter structure is utilized. As probing radiation, radio-frequency of UHF spectrum is utilized, as informative signs, characteristic peak values of frequency characteristic of direct transmission and reverse reflection coefficients are utilized. ^ EFFECT: minimal costs of industrial realization. ^ 6 cl, 5 dwg
