Introduction. The use of the Internet in committing offences against the sexual inviolability of minors is an emerging threat to their full mental and physical development. These crimes are characterised by a large number of victims suffering from a single person with a sexual behaviour disorder. The latent nature of such offences determines the scientific search for the practical ensuring of effective legal protection of minor's sexual inviolability on the Internet in line with the existing problems. Methods. General scientific methods of research (analysis, synthesis, comparison, generalisation) were used; private methods of research (system-structural, logical-legal) made it possible to comprehensively study the problem of sexual inviolability of minors and ways of its solution. The method of legal forecasting revealed the areas of legislative development on the problem to be solved. Results. The high social danger of indecent acts against minors online was revealed. This led to the development of specialised bodies for the protection of sexual inviolability of minors on the Internet in foreign countries, to the widespread introduction of artificial intelligence in the digital search for prohibited pornographic content. The author proposes to solve the problem under consideration in Russia by improving the legal regulation of supervision of persons convicted for violations of the sexual inviolability of minors through the “Safe City” system, as well as by restricting general access to the Internet for minors under the age of 14.
