A method and apparatus is provided for Contactless Hand Recognition (CHR)
for positive identification of cooperative individuals seeking access to
physical, logical, or informational systems. Contactless Hand Recognition
(CHR) is based on a novel technique and apparatus that rapidly and
contactlessly captures a livescan hand geometry video image with a
visible wavelength, infrared, or thermal camera of a person desiring
access, then reduces the image to a template, compares the livescan
template to a reference template, and determines if there is a match.
Contactless Hand Recognition (CHR) is a significant advancement over
current state-of-the-art hand recognition systems because authentication
is done contactlessly while on the move, and at a distance, while
simultaneously verifying liveness. It can also be combined with a
personal knowledge process to include the use of a Personnel
Identification Number (PIN), a secret contactless sign (SCS), or unique
hand/finger position biometrics known only to the user. The CHR invention
offers the possibility for users to have a rapid, fully contactless
three-factor system of authentication based on contactless tokens,
biometrics, and personal knowledge identification signs.
