Abstract: 1. The method of identification of controlled object authenticity, wherein forming the information about production characteristics of the object in digital form, said information is signed by electronic digital signature of a marker, the received information is transformed from digital form into the bar code, the bar code is put on the object or the label, fixed on the object, the bar code is checked and transformed into digital form, from which electronic digital signature of the marker and information about production characteristics of the object are extracted, authenticity of electronic digital signature and information about production characteristics of the object are checked, according to it, authenticity of the object is identified, characterized in that additionally, in the bar code the open key of electronic digital signature is reflected, the information about parameters of consumer characteristics of the object and parameters of the object producer in form of a letter and cipher text is formed and when the bar code is put on the object or the label, fixed on the object, simultaneously the letter and digital text about parameters of consumer characteristics of the object and parameters of the object producer is put on; while checking the bar code, the open key of checking of electronic digital signature is extracted, which is used for checking of authenticity of electronic digital signature; and the object identification, according to the results of ascertainment of authenticity of electronic digital signature of a marker and information about production characteristics of the object, is supplied by checking of the object authenticity by means of comparing information about parameters of consumer characteristics of the object and parameters of the object producer, put on the object or the label, fixed on the object, with actual parameters of consumer characteristics and parameters of the object producer; if they correspond to each other  the object is identified as an authentic one, according to the complex of authenticity of electronic digital signature, information about production characteristics of the object, parameters of consumer characteristics of the object and parameters of the object producer. 2. The method according to claim 1, wherein the code of a region, the code of a producer, number of demand for production of serial batch of objects and number of the object in a serial batch are used as parameters of the object producer. 3. The method according to claim 1 or 2, wherein the parameters are controlled visually, by touch, weight, color and odor are used as parameters of consumer characteristics of objects. 4. The method according to any of the preceding claims, wherein the code of a region, the code of a marker organization, the code of a producer, the code of a supplier, the type of the object, the date of production, the number of demand for production of serial batch of objects, the number of the object in serial batch are used as production characteristics.
