Title: A portable device having biometrics-based authentication capabilities
Inventor: POO TENG PIN
IPC: G06F21/34
Filed: 2002-03-22
Granted: 2004-10-05
Abstract: Apparatus and method for implementing biometrics-based authentication. In a preferred embodiment, the present invention is embodied in a portable device . Specifically, in one embodiment, the portable device includes a microprocessor, a non-volatile memory coupled thereto, and a biometrics-base d 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 information in the non-volatile memory is granted to that person; otherwise, access is denied. Embodiments of the present invention th us 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.

Abstract: A method and system are presented for identifying a customer in a commercial transaction using less than complete identifying information. A credit card purchase transaction is described wherein a name (24) for the customer is removed from the credit card. A trade area is then determined for the point of sale (20) utilizing historical sales at that point of sale. The trade area is then used to restrict a search of a demographic database (32) to find a list of potential identity matches (38) having names similar or identical to the name (24) on the credit card. A best match generator (40) then creates a profile (150) of the expected purchaser of the products in the transaction.  Using demographic information about each identity in the list of potential identity matches (38), each identity is compared to the profile (150) and given a score (156). Scores (156) can also be created by examining past purchases, or by examining the strength of the name match. The highest scoring identity is then considered the best match (46). The best match identity (46) is then assumed to be the identity involved in the transaction, and the customer database (34) is updated to reflect this determination.

Abstract: A display apparatus displays projected images to a user. A viewing station comprising a dummy cockpit structure receives the user such that the eye of the user at a point in time is at an eyepoint in a viewing volume of possible eyepoints defined by the range of movement of the user at the viewing station. First and second projection screen portions face the eyepoint. A first projector directs light to shine through an aperture in the first projection screen portion so as to project an image on the second projection screen portion. A mask is adjustably supported between the aperture and the viewing station, and is configured so that it covers the part of a last lens surface of the projector viewable through the aperture when viewed from any eyepoint in a viewing volume of possible eyepoints of the user, and prevents the user seeing light scattered from the last optical surface of the projector. The second projector projects light on the first screen portion and an inside surface of the mask so as to form thereon a second image visible to the user.
