METHOD OF OBJECT PROTECTION AGAINST FORGERY AND METHOD OF AUTHENTICITY CONTROL OF OBJECT PROTECTED AGAINST FORGERY

摘要

FIELD: technological processes. ^ SUBSTANCE: method of object protection against forgery includes application of information identifying mark to the surface of protected object by means of glue layer, in composition of which light-sensitive protein bacteriorhodopsin is introduced. Information identifying mark or its part is made transparent, and corresponding portion of protected object surface is made transparent or with mirror reflecting coating. During monitoring of object authenticity light-sensitive element that contains bacteriorhodopsin is illuminated, by means of two sources of light with lengths of waves, accordingly, in band of main and intermediate conditions of bacteriorhodopsin absorption. ^ EFFECT: invention allows to increase reliability of protection against forgery and monitoring of valuable documents and items. ^ 3 cl, 4 dwg
