Abstract: A system for identifying complete account identifiers from partial account identifiers is provided. The system includes an account identification computing device including at least one processor and a memory device in communication with the at least one processor. The processor is configured to receive transaction data including unique merchant identifiers, build a merchant table using the transaction data, and receive a list including partial account identifiers. The processor is further configured to determine, for each unique merchant identifier, a number of candidate account identifiers and calculate at least one metric based on the number of candidate account identifiers. The processor is further configured to identify a source unique merchant identifier and match at least one candidate account identifier to a complete account identifier by matching one of the partial account identifiers to the at least one candidate account identifier.

Abstract: A method and system for detecting fraudulent network events in a payment card network by incorporating breach velocities into fraud scoring models are provided. A potential compromise event is detected, and payment cards that transacted at a compromised entity associated with the potential compromise event are identified. Subsequent transaction activity for the payment cards is reviewed, and a data structure for the payment cards are generated. The data structure sorts subsequent transaction activity into fraud score range stripes. The data structure is parsed over a plurality of time periods, and at least one cumulative metric is calculated for each of the time periods in each fraud score range stripe. A plurality of ratio striping values are determined, and a set of feature inputs is generated using the ratio striping values. The feature inputs are applied to a scoring model used to score future real-time transactions initiated using the payment cards.

Abstract: A computer-implemented method for authenticating an online user with an access control server (ACS) is provided.

Abstract: A computer-implemented method for authenticating an online user includes steps including receiving, from a requestor server in communication with a merchant website, an authentication request message including authentication data collected from a user computing device during an online interaction with the merchant website. The steps also include extracting the authentication data from the authentication request message, and applying a risk-based authentication (RBA) engine to the authentication data to obtain RBA result data including a reason code that includes no more than three bytes of data. The steps further include causing the reason code to be embedded in an authorization request message generated during the online interaction and routed to a decisioning server via a payment network.

Abstract: A system is provided. The system includes a computing device including at least one processor in communication with at least one memory device. The at least one processor is programmed to receive a plurality of data points. The at least one processor is also programmed to sort the plurality of data points into chronological order. The at least one processor is further programmed to divide the plurality of data points into a plurality of subsets. Each subset of the plurality of subsets represents a period of time. In addition, the at least one processor is programmed to process each subset to determine a velocity value for the individual subset. Moreover, the at least one processor is programmed to combine the plurality of velocity values to determine a final velocity value.

The at least one processor is also programmed to extract the authentication data from the authentication request message, generate, based at least in part on the extracted authentication data, risk-based authentication (RBA) result data including a risk score, and route the RBA result data based on the authentication profile and the RBA result data.

Abstract: An authentication platform for authenticating an online user in a transaction without use of strong consumer authentication (SCA) includes receiving an authentication request message for a transaction involving a regulated market includes authentication data and a transaction value, extracting the authentication data from the authentication request message, generating risk-based authentication (RBA) result data, determining that a risk of fraud in the transaction satisfies a risk threshold established by the regulatory entity by evaluating the risk score relative to the risk threshold, determining that the transaction value is below a transaction limit set by the regulatory entity, the transaction limit identifies a threshold transaction value below which strong consumer authentication may be avoided for transactions satisfying the risk threshold, and transmitting an authentication response message authenticating the transaction without strong consumer authentication having been performed based on satisfying
