  • An Adaptive MPEG-4 Proxy Cache An Adaptive MPEG-4 Proxy Cache

    Co-Authors: Peter Schojer, Laszlo Böszörményi, Hermann Hellwagner
    Abstract:

    Abstract Multimedia is gaining ever more importance on the Internet. This increases the need for intelligent and efficient video caches. Typical Web proxies were not designed to efficiently support the caching of videos. A promising approach to improve caching efficiency is to adapt videos. With the availability of MPEG-4 it is possible to develop a standard compliant proxy that allows fast and efficient adaptation. We propose a modular design for an adaptive MPEG-4 video proxy that supports efficient full and partial video caching in combination with filtering options that are driven by the Terminal capabilities of the Client. We use the native scalability operations provided by MPEG-4 and use the emerging MPEG-7 standard to describe the scalability options for a video. The proxy parses the MPEG-7 description and decides, based on this description and the Terminal capabilities of the Client, which adaptation step to choose. Simple MPEG-4 audio-visual streams are supported by filter operations in the compressed domain that realize several temporal scaling algorithms and color reduction. In this paper, we will restrict ourselves to full video caching. The combination of adaptation with MPEG-4, MPEG-7 and Client Terminal capabilities is to the best of our knowledge unique and will increase the quality of service for end users

  • internet payment and loading system using smart card
    1998
    Co-Authors: Virgil M Davis, Suzanne C Cutino, Michael J Berg, Fredrick Sidney Conklin, Steven John Pringle
    Abstract:

    An architecture and system loads and uses a smart card (5) for payment of goods and/or services purchased on-line over the Internet (202). A Client module on a Client Terminal (204) controls the interaction with a consumer and interfaces to a card reader (210) which accepts the consumer's smart card (5) and allows loading and debiting of the card. Debiting works in conjunction with a merchant server (208) and a payment server (206). Loading works in conjunction with a bank server (860) and a load server (862). The Internet provides the routing functionality between the Client Terminal and the various servers. A payment server (206) on the Internet includes a computer and a security module (or a security card (218) in a Terminal (214)) to handle the transaction, data store and collection. A merchant server (208) advertises the goods and/or services offered by a merchant for sale on a web site. The merchant contracts with an acquirer to accept smart card payments for goods and/or services purchased over the Internet. A consumer uses his smart card (5) at the Client Terminal (204) in oder to purchase goods and/or services from the remote merchant server (208). The Client Terminal sends a draw request to the payment server. The payment server processes, confirms and replies to the merchant server (optionally by way of the Client Terminal). To load value, the Client Terminal (204) requests a load from a user account at the bank server (860). A load request is sent from the card (5) to the load server (862) which processes, confirms and replies to the bank server (optionally by way of the Client Terminal). The bank transfers loaded funds to the card issuer (108) for later settlement for a merchant from whom the user purchases goods with value on the card.

  • internet payment system using smart card
    1997
    Co-Authors: Virgil M Davis, Suzanne C Cutino, Michael J Berg, Fredrick Sidney Conklin, Steven John Pringle
    Abstract:

    An architecture and system uses a smart card for payment of goods and/or services purchased on-line over the Internet. A Client server on a Client Terminal controls the interaction with a consumer and interfaces to a card reader which accepts the consumer's smart card. A payment server on the Internet includes a computer and Terminals that contain security cards to handle the transaction, data store and collection. Also connected over the Internet is a merchant server advertising the goods and/or services offered by a merchant for sale on a web site. The merchant contracts with an acquirer to accept smart card payments for goods and/or services purchased over the Internet. A consumer uses his smart card at the Client Terminal in order to purchase goods and/or services from the remote merchant server. The Internet provides the routing functionality between the Client Terminal, merchant server and payment server. The Client Terminal emulates a security card in interacting with the smart card, and the responses received are grouped together and sent as a draw request message to the payment server. The payment server then emulates the smart card in an interaction with the security card. The security card delivers the expected smart card signature to the payment server and/or on to the Client Terminal or merchant server to reduce message traffic between the entities on the network. The comparison of the smart card signature to an expected value can occur at any location. Encryption is used for security.

  • internet payment authentication and loading system using virtual smart card
    2012
    Co-Authors: Virgil M Davis, Suzanne C Cutino, Margaret Reid, Steve R Hoffman
    Abstract:

    A system loads, authenticates and uses a virtual smart card for payment of goods and/or services purchased on-line over the Internet. An online purchase and load (OPAL) server includes a virtual smart card data base that has a record of information for each smart card that it represents for a user at the behest of an issuer. The server includes a smart card emulator that emulates a smart card by using the card data base and a hardware security module. The emulator interacts with a pseudo card reader module in the server that imitates a physical card reader. The server also includes a Client code module that interacts with the pseudo card reader and a remote payment or load server. A pass-through Client Terminal presents a user interface and passes information between the OPAL server and a merchant server, and between the OPAL server and a bank server. The Internet provides the routing functionality between the Client Terminal and the various servers. A merchant advertises goods on a web site. A user uses the Client Terminal to purchase goods and/or services from the remote merchant server. The payment server processes, confirms and replies to the merchant server. The payment server is also used to authenticate the holder of a virtual card who wishes to redeem loyalty points from a merchant. To load value, the Client Terminal requests a load from a user account at the bank server. The load server processes, confirms and replies to the bank server.
