  • Publication number: 20040034784
    Abstract: This invention provides a mechanism, which allows a user's personal identification number (PIN) to operate independently from a biometric authentication system. This improvement reduces the administrative burden of having to keep a user's PIN synchronized with the PIN used to access the user's smart card following successful biometric authentication. The first embodiment of the invention incorporates a cryptographic interface, which bypasses the PIN entry and allows the biometric authentication system to directly access card resources. The second embodiment of the invention provides a second system PIN having greater bit strength than the cardholder PIN. Both embodiments of the invention retrieve secrets (either a cryptographic key or system PIN) from a biometric database by comparing a processed biometric sample with known biometric templates. The biometric authentication system incorporates a client-server architecture, which facilitates multiple biometric authentications.

  • Publication number: 20040034783
    Abstract: This invention provides for progressive processing of biometric samples to facilitate verification of an authorized user. The initial processing is performed by a security token. Due to storage space and processing power limitations, excessive false rejections may occur. To overcome this shortfall, the biometric sample is routed to a stateless server, which has significantly greater processing power and data enhancement capabilities. The stateless server receives, processes and returns the biometric sample to the security token for another attempt at verification using the enhanced biometric sample. In a second embodiment of the invention, a second failure of the security token to verify the enhanced biometric sample sends either the enhanced or raw biometric sample to a stateful server. The stateful server again processes the biometric sample and performs a one to many search of a biometric database.

  • Patent number: 4025328
    Abstract: A microchannel plate for secondary electron emission intensification, having channel walls which are rounded so as to increase the interception of secondary electrons formed due to the incidence of primary electrons on the ends of the said channel walls.According to the invention, the method of manufacturing such a channel plate consists of softening the channel wall material and by bombardment of the glass of the input surface by means of an energy-carrying beam of high power for a very short period of time. The glass of the walls at the input surface side then assumes a rounded shape under the influence of gravity and the surface stress of the glass.

  • Patent number: 4025813
    Abstract: The invention relates to secondary-emissive microchannels which are bent to a given extent on the output side of the electrons. The said bending serves to restrict the areas where the electrons contact the channel walls to a small zone at the end of the electron multiplication and before the departure of the secondary electrons. The energy of the output electrons is thus dispersed very little.The emission of electrons can then be controlled by means of low electrical voltages which can be readily switched. The said partially curved microchannels are incorporated in electron tubes in the advantage of the ease of control, is utilized.

  • Patent number: 3987522
    Abstract: Method of manufacturing image display apparatus having a photocathode which is proximity focussed with respect to a micro-channel plate, comprising the steps of: positioning a photocathode substrate adjacent to the input face of a microchannel plate, the substrate having a surface facing the microchannel plate which may be altered by ion radiation bombardment; directing ion radiation from the channels of the microchannel plate by imposing a suitable voltage potential across the microchannel plate in a vacuum atmosphere to alter the surface of the substrate in a pattern of individual areas corresponding to the channels of the microchannel plate; forming a bowl-shaped photo-emissive recess at each of the altered individual areas; and spacing the substrate from the microchannel plate by a distance which results in each bowl-shaped photo-emissive recess being proximity focussed on the input aperture of the same channel that defined the individual area at which the bowl-shaped photo-emissive recess was formed.
