Abstract

Abstract Data key actuated devices such as high security doors are modified so that they periodically transmit an identity pattern. An authorized user is provided with a portable access device storing keys for a number of such key actuated devices, with each key associated with an identity pattern for that device. The portable access device has a stored template comprising a fingerprint of the authorised user combined with a verification code. When the authorized user applies their fingerprint to the portable access device, the verification code is returned which allows verification of the user. If the access device then receives a key actuated device identifier matching one in storage, the associated access key is retrieved and transmitted to the key actuated device to allow access to the user.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 84 words
A method for accessing data key actuated devices, comprising: receiving a key actuated device identifier from a key actuated device; receiving a biometric; determining whether said received biometric is an authorized biometric; comparing said received key actuated device identifier with stored key actuated device identifiers and, on finding a matching stored key actuated device identifier and where said received biometric is an authorized biometric, retrieving a stored access key associated with said matching stored key actuated device identifier; and transmitting said retrieved access key.
Claim 2
Independent Claim 84 words
A method for accessing data key actuated devices, comprising: receiving a key actuated device identifier from a key actuated device; receiving a biometric; determining whether said received biometric is an authorized biometric; comparing said received key actuated device identifier with stored key actuated device identifiers and, on finding a matching stored key actuated device identifier and where said received biometric is an authorized biometric, retrieving a stored access key associated with said matching stored key actuated device identifier; and transmitting said retrieved access key.
Claim 3
Dependent Claim 46 words
The method of claim 1 further comprising: responsive to determining said received biometric is an authorized biometric, initially transmitted a valid user indication; subsequently receiving a temporary key; and encrypting said retrieved access key with said temporary key prior to transmission of said retrieved access key.
Claim 4
Dependent Claim 30 words
The method of claim 2 wherein said initially transmitting a valid user indication is dependent upon finding a stored key actuated device identifier matching said received key actuated device identifier.
Claim 5
Dependent Claim 35 words
The method of claim 2 wherein each said stored access key is encrypted and including performing a decryption operation on a retrieved access key prior to encrypting said retrieved access key with said temporary key.
Claim 6
Dependent Claim 40 words
The method of claim 4 wherein said access keys are encrypted with a special key and wherein said performing a decryption operation comprises retrieving a template and attempting to recover said special key from said template utilizing said received biometric.
Claim 7
Dependent Claim 30 words
The method of claim 5 wherein said initially transmitting a valid user indication is dependent upon finding a stored key actuated device identifier matching said received key actuated device identifier.
Claim 8
Dependent Claim 40 words
The method of claim 1 wherein said determining whether said received biometric is an authorized biometric comprises utilizing a template comprising said authorized biometric and a verification code such that presence of said biometric allows recovery of said verification code.
Claim 9
Dependent Claim 144 words
A portable electronic access device comprising: a biometric input; a verifier responsive to said biometric input for verifying that a biometric which is input to said biometric input matches an authorized biometric and providing a verification indication; a memory storing a plurality of access keys, each for use in accessing a key actuated device and a plurality of key actuated device identifiers, each associated with one of said plurality of access keys; a receiver for receiving a key actuated device identifier; a comparator for, responsive to a verification indication from said verifier, comparing a key actuated device identifier received from a key actuated device with said stored key actuated device identifiers and, on finding a matching stored key actuated device identifier, retrieving a stored access key associated with said matching stored key actuated device identifier; and a transmitter for transmitting a retrieved access key.
Claim 10
Dependent Claim 144 words
A portable electronic access device comprising: a biometric input; a verifier responsive to said biometric input for verifying that a biometric which is input to said biometric input matches an authorized biometric and providing a verification indication; a memory storing a plurality of access keys, each for use in accessing a key actuated device and a plurality of key actuated device identifiers, each associated with one of said plurality of access keys; a receiver for receiving a key actuated device identifier; a comparator for, responsive to a verification indication from said verifier, comparing a key actuated device identifier received from a key actuated device with said stored key actuated device identifiers and, on finding a matching stored key actuated device identifier, retrieving a stored access key associated with said matching stored key actuated device identifier; and a transmitter for transmitting a retrieved access key.
