Using biometrics as an encryption key
First Claim
Patent Images
1. A method of analyzing a biometric part, comprising:
- receiving information indicative of a scan of a biometric part of an individual;
using a computer for analyzing said information to determine certain features of the biometric within said information, and for determining a reference within said scan of said biometric part, where said determining comprises determining the reference from said information of said biometric part, and for comparing said features with said reference; and
determining a value from said comparing said features with said reference, and using said value as indicative of the biometric.

Abstract
An image of an biometric part is used as encryption or decryption key. The biometric part image is obtained, and items within the biometric part are analyzed. Relationships between those parts are determined, (e.g. ratios) between different parameters of different parts. Those ratios are then used to form the key. A sequence of biometric information can be used in which case both the information itself and the sequence are used to form to the key.

9. A biometric analyzing device, comprising:
-
a scan part that receives information indicative of a scan of a biometric part of an individual; and a computer that analyzes said information to determine certain features of the biometric within said information, and compares said features with a reference that is itself determined from the biometric within said information, and determining a value from said comparing said features with said reference, and using said value as an output indicative of the biometric. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A biometric analyzing device, comprising:
-
a scanning part that receives information indicative of a fingerprint scan of a biometric part of an individual, said scanning part including an image sensor integrated circuit having an active surface which receives radiation, and where pixels of the active surface directly receive the fingerprint for scanning and where said pixels of said active surface are mapped directly in size to the fingerprint that is received, such that the size of one pixel on the sensor is the same size as the part of the fingerprint that said one pixel images ; and a computer that analyzes said information in a way that is independent of position and orientation. - View Dependent Claims (19, 20)
