Abstract: Methods, systems, and computer program products are provided for transaction fraud detection based on entity linking. Identifying data is collected associated with at least one transaction in a set of fraudulent transactions. A second set of transactions is searched for first linked transactions that include at least some of the identifying data. For each of the first linked transactions, the second set of transactions is recursively searched for additional linked transactions based at least in part on additional identifying data included in each of the first linked transactions. A fraud island is designated to include the at least one transaction, the first linked transactions, and the additional linked transactions. Whether a subsequent transaction is fraudulent is determined based on the fraud island and a transaction fraud risk model.

Abstract: Various embodiments provide techniques for determining a value share of a mobile transaction for one or more entities associated with the mobile transaction. Examples of mobile transactions include purchases of content such as applications, games, video, audio, graphics, and so on. In one or more embodiments, value share rules can be created and reconfigured. The value share rules specify a share of a transaction value (e.g., a percentage of revenue generated from a purchase of content) that an entity involved in a particular mobile transaction is credited with. In one example scenario, a user of a mobile device purchases an application for the mobile device. A value share rule can be applied to the application purchase amount to determine a share of the application purchase amount that is to be credited to a mobile operator that provides service for the mobile device.
