METHOD OF MONITORING ENFORCEMENT OF HOUSE ARREST WITH BIOMETRIC AUTHENTICATION OF MONITORED INDIVIDUAL Russian patent published in 2015 - IPC G08B25/00 G06K9/62 

FIELD: information technology.

SUBSTANCE: authentication device is used to store biometric data of a monitored individual by sensing a sequence from predefined handwritten words written by the monitored individual on a graphics pad. Each word is presented to the monitored individual before the individual repeats the word and the time allocated for the individual to write said word is limited. Further the biometric authentication device is trained to recognise said handwritten words and fragments thereof written by the monitored individual. Data input and training are carried out until first- and second-type error probability forecast falls to a given value for a predefined number of words. In authentication mode, verification words are presented to the monitored individual in a random sequence and the individual handwrites each verification word just presented recently. The obtained biometric data are then compared with reference data and an evaluation is made of the similarity of said words. The sequence of verification words presented to the individual is increased until a decision is made on the authentication result with the probability of first- and second-type errors, close to a predefined value.

EFFECT: high reliability of automated monitoring of enforcement of house arrest and avoiding the need to use hand and leg bracelets.
