METHOD OF DYNAMIC PERSONALITY biometric authentication on the specifics of handwriting

摘要

1. A method for dynamic biometric authentication of the individual features of handwriting, comprising: sampling an analog signal multicomponent reproducing playback handwriting dynamics, discrete quantization samples forming the matrix of quantized samples, its transformation to the digital mean values ​​of its elements for calculating identity matrix, wherein determining that the individual characteristics of handwriting for identity produce matrix obtained by two-dimensional th discrete Haar transform, thus creating base reference parameters handwriting samples users admitted to a computerized system, as an interval changing each identification parameter, newly introduced in user is identified by an identification matrix obtained by two-dimensional discrete Haar transform, the calculated maximum and the minimum value of the identifiable parameters, and the decision on the admission of any user in the system is accepted if the distance Hamming minimum, which is determined as the total number of deposition parameters for identifying valid ranges of values ​​of reference parameters handwriting samples users admitted to a computerized system, otherwise the message is formed of an unauthorized attempt to enter the sistemu.2. A method according to claim 1, characterized in that the intervals of acceptable values ​​of reference parameters handwriting samples users admitted to a computerized system, artificially increased by 20-40% compared with the estimated
