1. A method comprising:
receiving biometric data corresponding to a user, wherein the biometric data is represented as a first vector of floating point values;
receiving non-biometric data comprising a second vector of floating point values;
concatenating the biometric data with the non-biometric data into a third vector of floating point values;
permuting the third vector, wherein permuting the third vector comprises swapping locations of vector data elements within the third vector according to a seed associated with the non-biometric data; and
scaling each vector data element of the permuted third vector according to the seed to generate a biometric template corresponding to the received biometric data.
