Invention is related to methods of valuables counterfeit protection. Passive protective facility of preset structure is formed on valuable, and possibility for control of its availability and authenticity is provided. Protective facility material is represented by crystalline substances, for instance, ZnS, ZnSe, CdS, NaCl, LiNbO 3, Bi12GeO20, etc., at that detected informative criterion is actually defective acoustoluminescense formed by these materials after exposure of intensive ultrasonic waves. At that possibility of protective facility availability and authenticity control is provided be method of analysis by optical effects in process of external effects in process of external effect of probing ultrasonic exposure and detection of informative criteria in optic response of protective facility at mentioned external effect with further visual and automatic comparison of registered parameters of informative criteria with informative criteria contained in database of detection facility
