1. A method of verifying the identity of an unknown person, comprising the steps of:
- selecting at least one test joint of at least one test finger of a known person;
measuring the thickness of said test joint;
storing said measurement;
measuring the same joint thickness dimension of an unknown person;
comparing said joint thickness dimensions of said known and unknown persons to determine the degree of similarity therebetween;
and deciding whether said degree of similarity is acceptable as an indication of identity according to a selected criterion.

Abstract
A method and apparatus designed for verifying the identity of a person, for credit card authorization and other purposes, involves the measurement of the thickness of the knuckles and also the longitudinal distance between knuckles. The apparatus simultaneously takes a series of length and width measurements, and feeds them to a computer which is programmed to process the raw data and make comparisons to a standard previously recorded. Techniques for increasing the accuracy of the determination are also disclosed.
