  • Patent number: 8118218
    Abstract: Techniques for portable devices functioning as an electronic purse (e-purse) are disclosed. According to one aspect of the invention, a mechanism is provided to enable a portable device to conduct transactions over an open network with a payment server without compromising security. In one embodiment, a device is loaded with an e-purse manager. The e-purse manager is configured to manage various transactions and functions as a mechanism to access an emulator therein. The transactions may be conducted over a wired network or a wireless network. A three-tier security model is contemplated to support the security of the transactions from the e-purse. The three-tier security model includes a physical security, an e-purse security and a card manager security, concentrically encapsulating one with another. Security keys (either symmetric or asymmetric) are personalized within the three-tier security model.

  • Patent number: 7317394
    Abstract: A system, method and related software architecture are disclosed as a platform for developing and deploying RFID-enabled software applications. The platform is a framework between these applications and their connected physical RFID devices. The runtime version of this platform can be thought of as a logical RFID device. The platform allows RFID-enabled applications securely communicate with physical RFID devices to monitor their status and to access their tag data. The platform includes externalized APIs for accessing tag data, an event manager to alert applications of events coming from RFID devices and tags, data manager to filter and reconcile data returned from physical RFID readers before relaying them to applications, device manager to monitor the RFID device status for network management, and secured communication channels with data encryption.
