System and method for managing sonic token verifiers
First Claim
1. A system for authentication, comprising:
- a verifier that includes an acoustic receiving device to receive and record an audio label including a human voice or an acoustic signal from an audio speaker of a hand-held token, wherein the acoustic signal represents a digital signature associated with a unique key identifier generated by the hand-held token;
a data store coupled to the verifier that stores a data structure, wherein the data structure stores unique key identifiers of authorized hand-held tokens, and wherein each of the unique key identifiers is associated with a recording of an audio label including a human voice; and
a processor coupled to the data store, wherein the processor is to selectively grant access to at least one component associated with the verifier when the unique key identifier associated with the hand-held token is present in the data structure, and wherein the processor, in response to an acoustic signal addition request from one of the authorized hand-held tokens, is to add an additional key identifier and a recording of an additional audio label including a human voice associated therewith to the data structure.

Abstract
A hand-held token can be operated to generate an acoustic signal representing the digital signature generated by a private key of a public key/private key pair. Verifiers that might be located at, e.g., buildings, in vehicles, at bank ATMs, etc. receive the signal and retrieve the corresponding public key to selectively grant access authorization to components served by the verifiers. Methods and systems permit adding and removing a token from the access list of a verifier. Other methods and systems enable the token to be used with several verifiers that are nearby each other, such as might be the case with multiple vehicles owned by the same user and parked nearby each other, without more than one verifier being operated to grant access.

10. A system for authentication, comprising:
-
a verifier that includes an acoustic receiving device to receive and record an audio label including a human voice or an acoustic signal from an audio speaker of a hand-held token, wherein the acoustic signal represents a digital signature associated with a unique key identifier generated by the hand-held token, and, in response to the acoustic signal, accesses a data structure associated with the verifier, wherein the data structure stores unique key identifiers of authorized hand-held tokens and wherein each of the unique key identifiers is associated with a recording of an audio label including a human voice, and grants access to at least one associated component if the unique key identifier associated with the hand-held token is present in the data structure, wherein the verifier is coupled to a processor that removes the unique key identifier associated with the hand-held token from the data structure by correlating a captured human voice included in a removal request with an audio label associated with the unique key identifier, wherein the processor, in response to an acoustic signal addition request from one of the authorized hand-held tokens, adds an additional key identifier and a recording of an additional audio label including a human voice associated therewith to the data structure.

11. A method for authentication, comprising:
-
receiving a first acoustic signal at an acoustic receiving device of a verifier from an audio speaker of a hand-held token, wherein the first acoustic signal represents a digital signature associated with a key identifier generated by the hand-held token, and wherein the first acoustic signal is a request to add the key identifier associated with the hand-held token to a data structure accessible to the verifier, wherein the data structure stores unique key identifiers of authorized hand-held tokens and wherein each of the unique key identifiers is associated with a recording of an audio label including a human voice; recording an audio label including a human voice from the acoustic receiving device of the verifier; adding the key identifier to the data structure and the recording of the audio label including the human voice associated therewith in response to the first acoustic signal; receiving a second acoustic signal from the hand-held token at the acoustic receiving device of the verifier, wherein the second acoustic signal represents the digital signature associated with the key identifier and the hand-held token; accessing the data structure; and granting access to a component associated with the verifier if the key identifier is present in the data structure. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
