20090106151 | Fraud prevention based on risk assessment rule - A system, method, and computer-readable storage medium configured to import fraud prevention rules from an issuer and implement them in real-time at a payment processor. Usually, a card issuing bank either approves or declines financial transaction; however, in embodiments of the present invention, the issuing bank creates fraud prevention rules, and the payment processor implements the created rules. A payment processor apparatus comprises a network interface, and a verification engine. The verification engine includes a transaction driver, and a real time decisioning processor. The network interface is configured to receive a fraud prevention rule from a payment card issuing bank, and to receive a proposed financial transaction from an acquiring bank. The transaction driver receives the fraud prevention rule. The real time decisioning processor compares the proposed financial transaction from the acquirer and the fraud prevention rule to determine whether the proposed financial transaction should be declined. | 04-23-2009 |

20110173156 | TECHNIQUES FOR AUTOMATICALLY DISCOVERING A DATABASE DEVICE ON A NETWORK - Techniques for automatically adding a database device to a network of database devices include sending a first request from the database device over the network in response to detecting that the database device is connected to the network. In response to the first request, the database device receives data that identifies a database device-management server. The database device sends a second request to the database device-management server. The second request identifies the database device and requests that the device-management server register the database device as a database device on the network in response to the second request. The new database device may be a database appliance having a database process and a special purpose operating system tailored to the database process. With these techniques, a new database device can be plugged into a network and be automatically discovered, registered, and assigned management tasks without human intervention. This alleviates the load on human operators and makes adding database device to a network more reliable and simple. | 07-14-2011 |
