Abstract. The criminogenic situation in Russia today is characterized by a high level of crime. This is evidenced by the official data of the Federal State Statistics Service and the Ministry of Internal Affairs of Russia. In January 2020 alone, 496 crimes related to the use of weapons were committed. One of the problems that law enforcement agencies face when investigating crimes is establishing the authenticity or verification of items found during operational investigative actions. To increase the probability of verification of items, a number of preventive measures are necessary. As such a preventive measure, the protective marking of items of increased interest from criminal structures can act. The application of marking marks can be used to protect property rights, protect against counterfeit products, as well as by various law enforcement agencies for marking weapons. The protective properties of the marking are increased if it is latent, that is, it is not perceived visually, including with the help of available magnifying devices. In this work, the impact of operational factors on the dynamics of changes in the parameters of nanomarkings applied to steel parts is studied using a new innovative technology-scanning probe microscopy, which provides one hundred percent verification of subjects and objects.

Key words: protective nanomark, durability, steel, scanning probe microscope, dynamic lithography.
