METHOD OF PERMANENT AUTHENTICATION OF IDENTITY AND COMPUTER USER STATE BASED ON BEHAVIOUR PATTERNS Russian patent published in 2017 - IPC G06F21/31 

FIELD: information technology.

SUBSTANCE: method of permanent authentication of identity and computer user state based on behaviour patterns, consisting in registration of keyboard rhythm parameters with the specified time interval separately, jointly or in any combination: spelling error rate of any symbols, letter chains, microspaces between pairs of symbols, cursor control speed on monitor screen, pause sequence between mouse ear clicks or another control manipulator with the involvement of graphical interface, action sequence during launching the certain applications or working with them, as well as parameters of heart rate variability, galvanic skin response, respiratory rate; if one of the analysed parameters or several of them are deviated in any set from basic subset one or more of the following actions are carried out in any combination: access to task with which a user was working is blocked, access to application with which a user was working is blocked, access to computer with which a user was working is blocked, it is reported to security service, wherein basic parameters fixation of user operation both with computer in the whole and with single applications is carried out during authentication algorithm adaptation for at least three days during solution of any tasks formed with the specified probability within the safety concept, subset of states wherein the user authentication as a personality and authentication of psychophysiological states thereof as conditions necessary for specific form of activity is considered to be done; during user operation an ongoing monitoring with the specified within the safety concept time interval of all initially specified basic operation parameters.

EFFECT: increased level of information system protection due to decrease in probability of false user identification.
