FIELD: sealing important premises, such as radioactive material storehouses. SUBSTANCE: information member of seal is designed as piece of binding body which is deformed arbitrary by mounting seal and rigidly fixed between two transparent members of housing. When seal integrity is checked method involves comparison of checked image of information member to reference image of information member which is unique. Images are detected by identical optical tools; comparison is achieved by automatic image recognition tools. EFFECT: simplified design, facilitated use, prevention of faking even if reference image of information member is accessed. 6 cl, 1 dwg |
