  • Publication number: 20020094111
    Abstract: An automated access control apparatus and method. Identification data is compared with stored data to determine if a person should be granted access to an area, such as a residence. Video image data of entrances and attempted entrances is recorded and time and date stamped to permit playback in real time or at a later time for review. Playback can be accomplished over a cable television system. The apparatus can be integrated with a home security/alarm system.

  • Publication number: 20020093425
    Abstract: An automated access control apparatus and method. Identification data is compared with stored data to determine if a person should be granted access to an area. If granted access, the person is prompted to indicate a number of guests desiring access. As the person and the guests pass through entrance, the persons are counted and proper personnel is notified if an unauthorized number of persons enters the area. Unauthorized entries are recorded as image data that can be played in real time or at a later time for review. Guest entry is logged for billing purposes.

  • Publication number: 20020077905
    Abstract: A response to an advertisement driven stimulus is effected by locating a portable device at a terrestrial position at a point in time; identifying a fixed point advertisement in proximity to the portable device based upon the device's terrestrial position; and providing a response specific to the fixed point advertisement. The point in time is determined by activation of a switch associated with the portable device, whereafter the device is located by receiving a navigational signal. Communication is automatically established with a central data server where the fixed point advertisement is identified by comparing the terrestrial position of the portable device with a plurality of tabulated positions of fixed point advertisements. A unique identifier within the portable device and the position of the portable device are utilized by the data server to tailor a specific response to the advertisement based stimulus.

  • Publication number: 20020035542
    Abstract: A financial transaction authentication system utilizing non-invasive biometric verification which includes a first computer-based device having stored thereon encoded first human fingerprint data representative of an authorized human user, a control device with display and keyboard for enrolling said authorized human user in said first computer-based device, a second computer-based device connected to said first computer-based device via a communications network, a key-like device having embedded thereon an integrated circuit-based fingerprint sensor for real-time gathering of second human fingerprint data, a receptacle for said key-like device, a first and second mating electrical contact which connects said fingerprint sensor to said second computer-based device when said key-like device is inserted in said receptacle, and software resident within said second computer-based device for human user verification, which can include minutiae analysis, neural networks or other equivalent algorithms, for comparing

  • Patent number: 5386103
    Abstract: An identification and verification system which includes a card, or the like, having stored thereon human facial image projection characters, means for retrieving the human facial image projection characters and manipulating the same to produce an output signal indicative of a human facial feature for use in identification and verification. The retrieving means includes universal face space (UFS) memory indicative of facial features for a non-homogeneous population wherein the output signal is generated by projecting the projection characters into the UFS memory.
