Claim Text:
1. A computerized method for generating a new signature of a user to prevent user impersonation, comprising a computer processor steps of, a. fetching a signal from a non-volatile memory of at least one portion of at least one previously generated user's signature; b. generating at least one challenge sequence based on the signal to create a new signature; c. presenting the generated challenge sequence to the user; d. collecting the user's challenge response to the generated challenge sequence, and further comprising an events correlation mechanism that checks for use abnormalities of a user and generates a trigger to re-generate a challenge question if an abnormality is detected, wherein the abnormality comprises one or more of: conflicts in a user's known location, current activity, time length of transaction, repetition of visiting a transaction, time lapse between repeated transaction, distribution of transaction locations, speed of movement within same transaction location area, and speed of movement between different transaction location areas; e. computing a quality factor which represents a degree of correlation between any portion of the user's challenge response and any portion of the generated challenge sequence; f. generating a new signature based on any portion of user's challenge response and any portion of the previously generated signature and any portion of collectable information from user's device memory; g. storing the new signature and at least one of, the quality factor, a trust factor or a transaction quality factor in a non-volatile memory or communicating it to a computer program; and, h. wherein each challenge sequence and challenge response comprises any combination of one or more of textual, visual effects of display, picture, moving picture, video, audio, animation, advertisement format, computer code, and computer data objects.
