Abstract:
1. A method of authentication, the method comprising: receiving, by a processor, a plurality of first measurements, the plurality of first measurements corresponding to a first biometric parameter associated with a user, wherein at least some of the plurality of first measurements are obtained at different times; receiving, by the processor, a plurality of second measurements, the plurality of second measurements corresponding to a second biometric parameter associated with the user, wherein at least some of the plurality of second measurements are obtained at different times; analyzing, by the processor, the plurality of first measurements to obtain a first correlation value, wherein the first correlation value is a first degree of conformity of the plurality of first measurements; analyzing, by the processor, the plurality of second measurements to obtain a second correlation value, wherein the second correlation value is a second degree of conformity of each of the plurality of second measurements; combining, by the processor, the plurality of first and second measurements into a first composite dataset in which the plurality of first measurements are weighted according to the first correlation value and the plurality of second measurements are weighted according to the second correlation value; obtaining, by the processor, a first test measurement corresponding to the first biometric parameter; obtaining, by the processor, a second test measurement corresponding to the second biometric parameter; determining, by the processor, a confidence level of user authentication in view of a comparison of the plurality of first and second test measurements with the first composite dataset; analyzing, by a processor, the first test measurement in combination with the plurality of first measurements to obtain a third correlation value; and supplementing the plurality of first measurements with the first test measurement when the confidence level is above a threshold value and the third correlation value is within a predetermined range.
