Project involves use of infrared optical scanning of human hands to examine biometric capabilities when hands are double gloved.

(a. Objectives, b. Methodology, c. Ionizing Radiation, Radioactive Substances, or Chemical Substances to which human subjects are exposed, d. Involvement of Human Subjects [d.1. procedures used, d.2. risks if any])

OBJECTIVE DESCRIPTION AND SUMMARY

This project examines the biometric capabilities of infrared (IR) light (wavelength approximately 880 nm) as an imaging technique for human hands. The hands will be double-gloved with an inner plastic glove and an outer cotton glove.

The purpose of the project is determination of feasibility of hand imaging of sufficient quality to permit identification of a hand and the association with an individual for access control.

METHODOLOGY

An IR source, nominally an IR light emitting diode (LED), is used to mechanically scan the fingers and palm of a human hand. A sensitive IR receiver will be mechanically linked to the IR source and will detect transmitted IR. The transmitted signal will be used to construct an image of the hand, in particular the finger lengths and other biometric information, that can then be used for biometric testing.

A simple mechanical scanner has been constructed. The human hand is supported within this scanner and will not be moved during the scan time. Mechanical testing of this device was completed in FY2001 without human exposure.

HUMAN EXPOSURE

We expect no exposure to ionizing radiation, radioactive substances, chemical substances, or biological materials in this project. The human exposure will be limited to IR photons of wavelength approximately 880 nm.

INVOLVMENT OF HUMAN SUBJECTS

1. We began human subject testing, limited to hands, early in FY2002. The hand was placed in a light-shielded box containing the scanning device. The transmitted IR signal information (x and y coordinates) was digitized by a simple computer board and used to create an image of the hand.

2. The risks involved were limited to exposure to the IR photons. We have designed and installed light shields that will prevent light leakage from the scanner. Initial testing was restricted to low light levels and was increased as we gained experience with the equipment. Eventually, collimation was used to enhance spatial resolution. This reduced scattered IR very significantly, and with this reduction in scatter the possibility of external illumination of the person whose hand was being examined was minimized. We did provide suitable IR goggles that were worn during scanning.

3. A consent form has been written and approved by the IRB. All persons read and signed this form. These records are retained.

4. During FY2003 approximatley 61 subjects were examined. Each person's left hand was used for measurements. Usually three independant measurements were made on the hand. Some individuals had more or less exposure.

5. Data analysis is in process (mid-September 2003) and is expected to yield false acceptance ratio (FAR), false rejection ratio (FRR), and receiver operating curve (ROC) data for evaulation of this concept of hand identification.

SUMMARY

We have shown that this technique can produce useful images of hands when a protective glove is worn. The data obtained are extensive and satisfactory for biometric identification.

WORK FOR FY04

This project was cancelled in FY2004 at the sponsor's request. We completed the final report and a second report covering the hardware developed and modified specifically for this task. There was no human subject work in FY2004.
