METHOD FOR CERTIFYING USER BY EXTRACTING EMOTIONAL FEATURE FROM TYPING PATTERN USING WAVELET

摘要

A kind of purpose: method, for prove to extract by the formula pattern as using a small echo mood feature a user setting at reducing by the first staging error, it does not allow the time required for the access of a privileged user and user authentication, proves user base in the type of emotion mode of extraction. Construction: a pattern extractor judges that a character string is sequentially formed by the pressing key of key matrix and form/storage type pattern (203). Preliminary step is continued until the same amount of character string for becoming a user identifier (204) from the character string of key matrix. Search-type mode is applied to a wavelet detector by pattern extractor, and type pattern is compared with the memory-type feature of user (208). One fiducial value is compared with threshold together (209). If fiducial value is less than threshold, the access of user goes through (210).
