Portable device having biometrics-based authentication capabilities
DCFirst Claim
1. A unitary portable biometrics-based access control device which can be directly plugged into a universal serial bus (USB) socket communicatively coupled to a restricted resource, the device comprising:
- a housing;
a microprocessor housed within the housing;
a non-volatile memory coupled to the microprocessor and configured for storing user data and having a minimum of 8 MB of capacity;
a USB plug integrated into the housing without an intervening cable and configured for coupling the unitary portable access control device directly to the USB socket; and
a biometrics-based authentication module coupled to and controlled by the microprocessor, at least a portion of the biometrics-based authentication module being housed within the housing, wherein said biometrics-based authentication module is configured to grant access to the restricted resource provided that the biometrics-based authentication module authenticates the user'"'"'s identity and wherein access to the restricted resource is denied to the user otherwise; and
further whereinsaid biometrics-based authentication module is configured to grant access to the user data stored in the non-volatile memory provided that the biometrics-based authentication module authenticates the user'"'"'s identity and wherein access to the user data stored in the non-volatile memory is denied to the user otherwise,wherein the microprocessor is configured to provide a bypass mechanism for authentication upon a determination of authentication failure by the biometrics-based authentication module.

Abstract
Apparatus and method for implementing biometrics-based access control to a restricted resource. In a preferred embodiment, the present invention is realized using a portable device. Specifically, in one embodiment, the portable device includes a microprocessor, a non-volatile memory coupled thereto, and a biometrics-based authentication module controlled by the microprocessor. Preferably, the biometrics technology used is fingerprint authentication technology. The authentication module is capable of registering a fingerprint upon first use of the portable device, storing an encoded version of the fingerprint in the non-volatile memory. Subsequently, the authentication module can read a person'"'"'s fingerprint and reliably determine whether the fingerprint matches the registered fingerprint stored in the non-volatile memory. If a match is found, access to the restricted resource is granted to that person; otherwise, access is denied. Embodiments of the present invention thus provide a highly convenient, secured and reliable method and system for user authentication and access control which was not achievable in prior art password-based authentication approaches.
