Heart/Pulse Patterns
Measuring the user’s pulse or heartbeat ensures that a real person 
is providing the biometric factor. It is often employed as a secondary biometric to sup-
port another type of authentication. Some researchers theorize that heartbeats are unique 
between individuals and claim it is possible to use electrocardiography for authentication. 
However, a reliable method has not been created or fully tested. 
Voice Pattern Recognition
This type of biometric authentication relies on the characteris-
tics of a person’s speaking voice, known as a voiceprint. The user speaks a specifi c phrase, 
which is recorded by the authentication system. To authenticate, they repeat the same 
phrase and it is compared to the original.
Voice pattern
recognition is sometimes used as an 
additional authentication mechanism but is rarely used by itself. 
Speech recognition is commonly confused with voice pattern recognition, 
but they are different. Speech recognition software, such as dictation soft-
ware, extracts communications from sound. In other words, voice pattern 
recognition differentiates between one voice and another for identifica-
tion or authentication, whereas speech recognition differentiates between 
words within any person’s voice.
Signature Dynamics
This recognizes how a subject writes a string of characters. 
Signature dynamics
examine both how a subject performs the act of writing and 
features in a written sample. The success of signature dynamics relies on pen pres-
sure, stroke pattern, stroke length, and the points in time when the pen is lifted from 
the writing surface. The speed at which the written sample is created is usually not an 
important factor.
