摘要： Rules, applied to deny authorization of likely fraudulent transactions, are derived from a modified Patient Rule Induction Method algorithm that uses a target variable and a data set of past transactions each associated with a plurality of input variables and a hyper-rectangle enclosing a multi-dimensional space defined by a representation of the input variable values as points within the multi-dimensional space. While a count of the points within the hyper-rectangle is greater than a minimum support parameter, a first plurality of points proximal to edges of the hyper-rectangle are removed, where each such removing maximizes a mean value of the target variable, and then, while the mean value remains maximized, a second plurality of points proximal to the edges is added, where each adding maximizes or maintains the mean value. The hyper-rectangle is bounded within a minimum bounding box that defines the rules.

摘要： Embodiments of the present invention are directed to methods, apparatuses, computer readable media and systems for securely processing remote transactions. One embodiment of the invention is directed to a method of processing a remote transaction initiated by a mobile device comprising a server computer receiving a payment request including encrypted payment information. The encrypted payment information being generated by a mobile payment application of the mobile device and being encrypted using a third party key. The method further comprises decrypting the encrypted payment information using the third party key, determining a transaction processor public key associated with the payment information, and re-encrypting the payment information using the transaction processor public key. The method further comprises sending a payment response including the re-encrypted payment information to a transaction processor. The transaction processor decrypts the re-encrypted payment information using a transaction processor private key and initiates a payment transaction.

摘要： Methods and systems for providing data retrieved and analyzed as part of an authentication process for a user device to other entities of a transaction system are disclosed. This data can be used by other entities of the transaction system to enable more secure authorization processes for transactions. A risk score generated for a payment application server computer and the data used to generate the risk score can be leveraged to provide an issuer with more detailed data to ensure that the user engaging in a transaction is authenticated and that transactions being processed by the issuer are not fraudulent.

摘要： Embodiments are described that are directed to optimizing the provisioning of payment account credentials to mobile devices utilizing mobile wallets. In some embodiments, one of multiple provisioning schemes may be selectively chosen for payment account credential provisioning based upon a determined risk involved with a particular provisioning request. A low risk provisioning request leads to an immediate provisioning of a payment credential, whereas a provisioning request of high risk results in the provisioning request being denied. In some embodiments, medium risk provisioning requests will cause an additional user authentication to be performed before the payment account provisioning is finalized. The additional user authentication may occur using a separate communication channel than the channel in which the provisioning request was received.

摘要： 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.
