OBJECTIVE DESCRIPTION AND SUMMARY
This project examines the biometric capabilities of IR irradiation (approximately 1064 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 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. The mechanical testing of this device was completed in FY01 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 approximately 1064 nm.
INVOLVMENT OF HUMAN SUBJECTS
1. We began human subject testing, limited to hands, early in FY02. The hand was placed in a light shielded box containing the scanning device. The transmitted IR signal (X, Y) 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 our IRB. All persons read and signed this form. These records are retained.
SUMMARY
We have shown that this technique can produce useful images of hands when a protective glove is worn. The data obtained is extensive and is satisfactory for biometric identification.
PROJECTED WORK FOR FY03
We expect to continue this work in FY03 to examine the False/True Acceptance capabilities of this system. This will involve a more rapid analysis method using data already collected. In addition we expect to examine additional hands to enhance the data base.
