Abstract: A system is provided for estimating quantile values for fraud assessments. The system includes a processor and a computer readable medium operably coupled thereto, to perform operations which include capturing one or more first data values for a quantile value profile associated with an entity, wherein the quantile value profile includes one of real values or a first plurality of quantile marker values calculated from the real values, accessing the quantile value profile for the entity, determining a first number of the one or more first data values, and based on the first number of the one or more first data values and the one of the real values or the first plurality of quantile marker values in the quantile value profile, performing one of a first merge operation, a second merge operation, or a third merge operation.

Abstract: A system and method for performing real-time analytics detection where a current profile update is derived from a current incoming transaction for an entity and stored in a profile update table, an up-to-date profile for the entity is derived from the most recent profile stored in a profile table and from all recent profile updates stored in the profile update table for the entity which are more recent than the last time the most recent profile was last updated, the up-to-date profile is utilized to perform the detection, and, the current profile is updated in a consistent manner, without utilizing an update lock on the profile table, by only updating the profile in the profile table based on the recent profile updates which are earlier than a current time minus a synchronization period which is larger than a maximum potential time difference between different clocks in the system.
