Authentication via biometric passphrase

Abstract:

A system, method and computer program product for granting access and/or an authorization are disclosed. For instance, a computer-implemented method may include receiving a first sequence of plurality of biometric data elements. The sequence of plurality of biometric data elements may comprise a biometric passphrase. The method may include registering the biometric passphrase to a known user and/or a transaction account. The method may include receiving a transaction request comprising a second sequence of plurality of biometric data elements. The method may include comparing the second sequence of plurality of biometric data elements to the biometric passphrase to resulting in a confidence factor of the comparison. The comparison may include comparing the sequencing of the second sequence of plurality of biometric data elements and the characteristics of each biometric data element of the second sequence of plurality of biometric data elements to the biometric passphrase.
