Abstract
A personal identification system employs a matrix of pressure sensors mounted to a plate having a template of a human hand. When a person's hand is placed on the plate and overlying the template a pressure profile of the person's hand is provided. This profile is compared with a stored pressure profile of the same person's hand. If the pressure points or profiles correlate a positive identification of the person is made.
Claims20
A personal identification apparatus for measuring tactile pressures exerted by a person's hand and indicative of his identity, comprising:
- a matrix plate having a plurality of pressure sensors distributed on said plate, each operative to provide an output signal proportional to a pressure applied to said plate at the area at which said sensor is located, to enable said sensors to provide said output when a person's hand is emplaced on said plate to exert a pressure on said matrix,
- storage means for strong pressure profile signals of enrolled persons requiring identification,
- means for comparing said stored pressure profile with said output pressure signals to provide a favorable comparison when said output signals conform to said stored profile signals for positively identifying said person.
A personal identification apparatus for measuring tactile pressures indicative of a person's identity, comprising:
- a replication matrix indicative of a template of a hand and capable of accommodating typical variations of people's hand size,
- a plurality of pressure sensors distributed within said matrix, each providing an output signal when a person's hand is emplaced to exert pressure on said matrix,
- storage means for storing pressure profile signals of enrolled persons having access to said personal identification apparatus,
- means for comparing said provided output signals with said stored profile signal indicative of a person to be identified to provide a favorable comparison when said output signals conform to said stored profile signals for positively identifying said person.
A method of performing personal identification of a user who requires identification to be authorized, comprising the steps of:
- providing a matrix of pressure sensors on a plate to which said user's hand can be emplaced,
- first employing said user's hand on said plate to cause selective pressure sensors responsive to the pressure applied by said hand to provide profile output signals,
- storing said output signals in a memory to obtain a hand pressure profile for said user.
