Device-agnostic access control techniques

Abstract

A system can efficiently control access to an interactive computing environment. The system can receive authentication data of an authentication attempt associated with an entity. The system can determine, for the entity, a historical vector including features that include sub-features. The historical vector can be determined by generating synthetic data, generating weights, and determining probabilities. The synthetic data can be based on historical authentication attempts by entities other than the entity. The weights can correspond to sub-features of the historical vector. The probabilities can indicate a likelihood that a corresponding sub-feature is involved in the authentication attempt. The system can compare the historical vector to the authentication data. The system can generate a responsive message based on the comparison for controlling access to the interactive computing environment.
