  • Patent number: 7636696
    Abstract: A system, method, and computer program product for maintaining the anonymity of a consumer in a transaction with a retailer. The consumer provides payment method information and ship-to address information to a trusted third party. The consumer purchases products from a retailer by providing the trusted third party anonymous identifiers (e.g., nicknames, unique codes, or one time use codes either supplied by the consumer or by the trusted third party) corresponding to the selected payment methods and ship-to addresses. The retailer requests payment approval from the trusted third party. The trusted third party receives payment approval from a payment partner using the payment method information determined from the anonymous identifier received from the consumer. The trusted third party provides payment approval to the retailer along a transaction unique shipment identifier to place on the parcel.

  • Patent number: 6035039
    Abstract: In a mobile satellite system, a mobile communication system includes a fraud detection and user validation system and method for commissioning the mobile communication system in the mobile satellite system. The method includes the steps of generating a first input signal by the mobile communication system upon initialization, and transmitting the first input signal from the mobile communication system to the central controller. The method also includes the steps of generating a first security key in the central controller using the first input signal, and generating a second security key in the mobile communication system using the first input signal and transmitting the second security key to the central controller. The central controller verifies the mobile communication system that transmitted the first input signal to commission it in the mobile satellite system. The verification process is responsive to a comparison of the first security key with the second security key.

  • Patent number: 5708716
    Abstract: An authentication system authenticates a mobile communication system each time it attempts to register or communication in a mobile satellite system. The authentication system stores a first security key to establish communication in the mobile communication network system. The system generates a second security key having first and second components using a first process having first and second input signals. The first input signal includes the first security key, and the second input signal includes at least one of a transmit frequency and a receive frequency. The system generates a third security key using a second process having third and fourth input signals. The third input signal includes the second component of the second security key and the fourth input signal is a random number. Advantageously, the system verifies that the mobile communication system is authorized to establish communication using at least one of the first, second, third and fourth components of the second and third security keys.
