Abstract:
1. A method of authentication, the method comprising: obtaining from a user a plurality of first measurements corresponding to a first biometric parameter, wherein at least some of the first measurements are obtained at different times; obtaining from the user a plurality of second measurements corresponding to a second biometric parameter, wherein at least some of the second measurements are obtained at different times; analyzing the plurality of first measurements to obtain a first correlation value of the first measurements using a computing device; analyzing the plurality of second measurements to obtain a second correlation value of the second measurements; combining the first and second measurements into a first composite dataset in which the first measurements are weighted according to the first correlation value and the second measurements are weighted according to the second correlation value; obtaining a first test measurement corresponding to the first biometric parameter; obtaining a second test measurement corresponding to the second biometric parameter; providing a confidence level of user authentication based on a comparison of the first and second test measurements with the first composite dataset; supplementing the plurality of first measurements with the first test measurement if the confidence level is above a first threshold value; and withholding the second test measurement from augmenting the plurality of second measurements when the confidence level is above the first threshold value and below a second threshold value.
