Increasing internal state security requires an understanding of the factors that influence commission repetitive crimes (recidivism) since crime is not caused by public danger but criminal person. Against background informatization information activities law enforcement agencies, there no doubt about expediency using artificial intelligence algorithms and blockchain technology to predict prevent crimes. The prediction machine-learning models for identifying significant (individual...
