First Claim
Patent Images
1. An apparatus for identifying an individual comprising:
- radiation source means adapted to illuminate a region of the skin of an individual which is substantially opaque to visible radiation but substantially transparent to radiation from said source,means for detecting radiation from said source means reflected from the individual and sensitive to lateral variations and intensities of said reflected radiation so as to detect the arrangement of subcutaneous blood vessels in said region of the skin, wherein said means for detecting includestransducer means for generating a signal indicative of the variation of the arrangement of subcutaneous blood vessels; and
comparator means for comparing said signal with a reference signal characteristic of the individual.

Abstract
The arrangement of veins is a unique characteristic of an individual. Identification is performed by means of a detector (9) which scans a region of the skin (6) and detects the position of subcutaneous blood vessels (8) by measurement of a parameter such as the reflection of incident radiation. Comparison of the measured pattern with a predetermined pattern provides identification of the individual.
