Abstract
A technique for mapping a biometric credential of a user to a data value such as a key or password. A database stores multiple entries of biometric templates and associated data values for different users. One of the entries is a match for a particular user, and the remaining entries are randomly selected. The number of entries is reasonably large to provide a desired degree of randomness for a given entry, but smaller than a key space of the data values. Based on an input of a biometric sample of the user, a best match is selected from the entries of biometric templates, and the associated data value is used to authenticate the user. Two- or three-factor authentication can be provided. Additional factors can include a password provided by the user and a key which is encrypted by the data value of the matching entry.
