Abstract:
1. A method for determining if a user of a device is an authenticated user, said device having a plurality of sensors for biometric data, the method comprising: a) selecting two of said plurality of sensors, said plurality of sensors being in said device; b) gathering data from each sensor selected in step a); c) correlating data gathered from said two sensors such that data points gathered at similar instances are matched with one another to result in data pairs, each data pair having a data point from one sensor and a data point from another sensor; d) determining at least one characteristic loop from said data pairs, each characteristic loop being a loop formed when said data pairs are plotted; e) retrieving signature characteristic data, said signature characteristic data being derived from data resulting from biometric data from said authenticated user said signature characteristic data being data against which data gathered from said sensors are compared with; f) determining a signature characteristic loop from said signature characteristic data; g) comparing characteristics of said at least one characteristic loop determined in step d) with characteristics of said signature characteristic loop determined in step f), said comparing including calculating a discriminate function for each of said at least one characteristic loop and said signature characteristic loop and comparing resulting discriminate functions; h) if a comparison of said characteristics compared in step g) produces results not within predetermined limits, determining that said user is not said authenticated user i) if a comparison of said characteristics compared in step g) produces results within predetermined limits, determining that said user is said authenticated user.
