Abstract: A mobile computing device is adapted to transmit to a scoring server URLs of websites browsed using the device. The scoring server can compare these URLs against a merchant URL obtained within a preselected time period from transaction data resulting from a transaction involving a payment product of the device user. A score can be calculated based on the similarity between each URL obtained from the device and the URL from the transaction data. The score represents the likelihood that a website browsed using the device and, as a result, the transaction, is fraudulent. The browsed URLs can also be scored against a database of known fraudulent websites. A notification concerning the legitimacy of the transaction based on the score can be generated and sent to the mobile device in real-time. On receiving the notification, the device can be used to either accept or decline the transaction in real-time.

Abstract: A method and system is disclosed herein for conducting money or value point transactions between a first mobile device and a second mobile device in a network of a plurality of mobile devices. Each mobile device contains a radio frequency identification module with a digital wallet on each said mobile device for storing and processing digital value points. Digital certificates are provided in each mobile phone for the purpose of authenticating the mobile devices. The transaction is initiated by the first mobile device with the second mobile device by exchanging RFID identifiers and digital certificates via radio frequency identification transmission and reception. Digital certificates can be exchanged between the digital wallets of the first and second mobile devices using radio frequency transmission. The method and system disclosed herein allows users equipped with RFID enabled mobile devices to transact over a short range without a need for connectivity to a banking infrastructure or a central network.
