Fraud Detection and Analysis System
First Claim
1. A system comprising:
- a risk engine executing on a processor and coupled to a financial system that includes an account, the risk engine generating an account model corresponding to a user and events conducted in the account, the generating of the account model using event parameters of a previous event performed by the user in the account to generate predicted distributions of the event parameters for a next event in the account, the risk engine receiving event parameters of the next event as the next event occurs, the risk engine generating a first probability using the account model, wherein the first probability is a probability of observing the event parameters assuming the user is conducting the next event, the risk engine generating a second probability using a fraud model, wherein the second probability is a probability of observing the event parameters assuming a fraudster is conducting the next event, wherein the fraudster is a person other than the user, wherein the events conducted in the account comprise the previous event and the next event, the risk engine generating a risk score using the first probability and the second probability, the risk score indicating the relative likelihood the next event is performed by the user versus the fraudster; and
a risk application executing on the processor, the risk application comprising an analytical user interface (AUI), the AUI displaying for any event in the account at least one of the risk score and the event parameters.

Abstract
A system is provided comprising a risk engine coupled to a financial system that includes an account. The risk engine generates an account model corresponding to a user and events of the account. Generation of the account model uses event parameters of a previous event performed by the user in the account. The risk engine uses the account model to generate a first probability of observing event parameters assuming the user is conducting the next event. The risk engine uses a fraud model to generate a second probability of observing event parameters assuming a fraudster is conducting the next event. The risk engine generates a risk score, using the first and second probabilities, which indicates the relative likelihood the next event is performed by the user. The system includes a risk application comprising an analytical user interface that displays for any event the risk score and/or event parameters.

65. A system comprising:
-
a risk engine executing on a processor, the risk engine receiving from a financial system observations corresponding to a prior event, the prior event including actions taken in an account of the financial system during electronic access of the account, the risk engine estimating parameters of an account model using the observations and dynamically generating an account model to include the parameters, the account model corresponding only to the user, the risk engine using output of the account model to generate a risk score that is a relative likelihood an event in the account following the prior event is performed by the user versus the fraudster; and a risk application executing on the processor, the risk application comprising an analytical user interface (AUI), the AUI displaying for any event in the account at least one of the risk score and event parameters of any event in the account.
