The article proposes a systematic approach to the analysis of psychological perception of information at the level of human intuitive perception. The most successful, according to the authors, methods and approaches of building information models of sensory perception of information are given. Such a systematic approach “from simple to complex and from it to generalization” made it possible to determine the features of each of the considered methods, to determine their advantages and disadvantages, and to indicate the directions of appropriate use.

The authors proposed and implemented a method of identifying computer users based on the measurement of various time delays when entering information from the computer keyboard. In order to increase the accuracy of identification, it is recommended to use the relative values of pauses before and after pressing a key to the time it is held. This approach provides a 15 % increase in recognition accuracy and reduces time and resource costs for identification.

In order to automate the process of identification of a person working at a computer for a long time, adaptation of the developed product to changing the user’s keyboard handwriting by changing the handwriting sample is provided.

Considerable attention is paid to clarifying the concepts of sign, image, meaning, meaning, which reflect the psychological aspects of information perception by a computer user
