Method and apparatus for electro-biometric identity recognition
First Claim
1. A method for identifying an individual, comprising:
- a preliminary step of obtaining representations of the heartbeat patterns of a plurality of individuals, and deriving and storing the representation of the common features of the heartbeat patterns of a plurality of individuals from at least a selected number of representations;
producing and storing a first biometric signature that identifies a specific individual by forming the difference between a representation of the heartbeat pattern of the specific individual and the stored representation of common features of heartbeat patterns of a plurality of individuals;
after said producing step, obtaining a representation of the heartbeat pattern of a selected individual and producing a second biometric signature by forming the difference between the heartbeat pattern of the selected individual and the stored representation of the common features of the heartbeat patterns of the plurality of individuals; and
comparing said second biometric signature with the first biometric signature to determine whether the selected individual is the specific individual.

Abstract
A method and apparatus for electro-biometric identity recognition or verification, producing and storing a first biometric signature that identifies a specific individual by forming the difference between a representation of the heartbeat pattern of the specific individual and a stored representation of common features of the heartbeat patterns of a plurality of individuals; after the producing step, obtaining a representation of the heartbeat pattern of a selected individual and producing a second biometric signature by forming the difference between the heartbeat pattern of the selected individual and the stored representation of common features of the heartbeat patterns of the plurality of individuals; and comparing the second biometric signature with the first biometric signature to determine whether the selected individual is the specific individual.

14. Apparatus for identifying an individual, comprising:
-
means for producing and storing a first biometric signature that identifies a specific individual by forming the difference between a representation of the heartbeat pattern of the specific individual and a stored representation of common features of the heartbeat patterns of a plurality of individuals; means for obtaining, after the first biometric signature has been produced and stored, a representation of the heartbeat pattern of a selected individual and producing a second biometric signature by forming the difference between the heartbeat pattern of the selected individual and the stored representation of the common features average of the heartbeat patterns of the plurality of individuals; and means for comparing said second biometric signature with said first biometric signature to determine whether the selected individual is the specific individual. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
