  • Publication number: 20140279416
    Abstract: A transaction in a sequence of transactions is received and a transaction group with which the transaction is associated is determined, as well as transaction group signature data of the transaction group with which the received transaction is associated. A transaction score for the received transaction is generated, in response to determining that the received transaction is a last transaction in the transaction group with which the received transaction is associated, and a transaction group score is generated for the transaction group with which the received transaction is associated, such that the transaction group score is generated based on all transactions in the sequence of transactions that are associated with the transaction group.

  • Patent number: 8805737
    Abstract: Systems and methods are provided for operation upon data processing devices are provided for operating with a fraud detection system. As an example, a system and method can be configured for receiving, throughout a current day in real-time or near real-time, financial transaction data representative of financial transactions initiated by different entities. At multiple times throughout the day, a summarization of the financial transaction data (which has been received within a time period within the current day) is generated. The generated summarization is used to determine whether fraud has occurred with respect to a financial transaction contained in the received authorization data or with respect to a subsequently occurring financial transaction.

  • Publication number: 20120317027
    Abstract: Systems and methods are provided for providing real-time scoring of received transaction data. Transaction data describing a particular transaction that has occurred is received. The transaction data is stored in an enterprise database, where the enterprise database is configured to store transactions of disparate types, where the transaction data is stored using a plurality of segments, where a segment is formatted according to a template, and where the template is selected based on an attribute of the transaction, wherein the attribute is a customer attribute, an activity attribute, or a channel attribute. A transaction type of the particular transaction is determined. One or more models are selected from a pool of models based on the transaction type, wherein the one or more models are configured based on a plurality of records from the enterprise database, and a score of the received transaction data is generated based on the transaction data.

  • Publication number: 20120317008
    Abstract: Systems and methods for storing transaction data associated with transactions of disparate types are provided. Transaction data is received describing a transaction that has occurred, the transaction being performed by an customer of a particular customer type and the transaction being performed using a channel of a particular channel type. Transaction data about the customer is stored in an customer segment according to one of a plurality of customer templates, the one of the plurality of customer templates being selected according to the customer type. Transaction data about the channel is stored in a channel segment according to one of a plurality of channel templates, the one of the plurality of channel templates being selected according to the channel type. Data from the customer segment, the activity segment, and the channel segment for the transaction is extracted and scored by a predictive model.

  • Publication number: 20120317013
    Abstract: Systems and methods are provided for scoring transaction data representative of transactions of disparate types transaction data describing a transaction that has occurred is received. The transaction data is stored in a plurality of segments, where a segment is formatted according to a template, where the template is selected based on an attribute of the transaction, and where the attribute is a customer attribute, an activity attribute, or a channel attribute. Transaction data associated with a segment is aggregated based on a particular attribute. The aggregate transaction data is provided to a predictive model to generate a fraud score. New transaction data is received describing a new transaction, wherein the new transaction includes the particular attribute. A real-time score is provided indicating a likelihood of fraud for the new transaction, wherein the score is based at least in part on the fraud score generated using the aggregate transaction data.

  • Patent number: 7813944
    Abstract: Detection of insurance premium fraud is provided by a predictive model, which uses derived variables to assess the likelihood of fraud for each policy. The predictive model produces a score, which is a measure of the likelihood of premium fraud or abuse. The predictive model is included in a system that accepts policies to be considered for scoring, selects which policies are appropriate for scoring, stores data about the policies in a database, uses the data to derive variables for the model, and processes and outputs the model scores and related information. A rule-based analysis, which detects specific inconsistencies in the data that are indicative of premium fraud, may also be part of the system. The model scores and red-flag indicators from the rule-based analysis may be further processed to provide customized output for users.

  • Patent number: 7788195
    Abstract: Systems and methods for performing fraud detection. As an example, a system and method can be configured to build a set of predictive models to predict credit card or debit card fraud. A first predictive model is trained using a set of training data. A partitioning criterion is used to determine how to partition the training data into partitions. Another predictive model is trained using at least one of the partitions of training data in order to generate a second predictive model. The predictive models are combined for use in predicting credit card or debit card fraud.

  • Patent number: 7379880
    Abstract: Computer implemented processes and software products generate profiles of entities, such as providers, clients, merchants and customers, and entities comprising interacting pairs of entities. The processes including deriving direct profiles from transaction data pertaining to an entity and enhancing the profile of one entity using the profile of another entity. Parallel and serial applications of the derive and enhance processes on various individual and multiple entites yields enhanced profiles that powerfully describe the interactions and relationship of the entities to each other, and between their members.
