Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 uniq…
