First Claim
Patent Images
1. A computer-implemented method for biometric authentication, said method comprising:
- reading a first unique, heartbeat waveform of an individual;
analyzing said waveform to identify unique traits;
reading a second unique, internal physiological trait of said individual; and
authenticating the identity of said individual if both said waveform and said physiological trait correspond with previously enrolled traits recorded for said individual.

Abstract
A portable biometric authentication system having a single technology for measuring multiple, varied biological traits to provide individual authentication based on a combination of biological traits. At least one of these biometric traits is a live physiological trait, such as a heartbeat waveform, that is substantially-but not necessarily completely-unique to the population of individuals. Preferably, at least one of the identifying aspects of the biological traits is derived from a measurement taken by reflecting light off of the subdermal layers of skin tissue.

19. A computer-implemented method performed by a computer authenticating device comprising:
-
presenting an individual'"'"'s live body tissue to the computer authenticating device for the capturing of a first unique, heartbeat waveform of said individual; analyzing said waveform to identity unique features; providing a second unique, internal physiological identifier of said individual to said authentication device; authenticating said second physiological identifier by comparing the unique features with those recorded for that individual; and upon authentication by said device, operating said device to perform functions previously inaccessible to unauthorized individuals, said authentication taking place upon the matching of both of said biological identifiers with previously enrolled physiological identifiers taken for said individual. - View Dependent Claims (20, 21, 22, 23, 24)
