Fraud detection and analysis
First Claim
1. A method comprising:
- generating relationships between event parameters of events and derived parameters corresponding to an account, wherein the events include actions taken in the account during access of the account;
automatically generating and dynamically updating an account model from the relationships;
predicting, during future events with the account model, when a fraudster is perpetuating the future events;
wherein;
predicting when the fraudster is perpetuating the future events comprises predicting expected behavior that includes generating expected event parameters of the future events; and
generating the expected event parameters of the future events includes generating fraud event parameters using a fraud model, wherein;
generating the fraud event parameters assumes a fraudster is conducting the future events;
the fraudster is any person other than an owner of the account, and wherein said fraud model includes a predictive fraud model;
the predictive fraud model is automatically generated by estimating a plurality of fraud components of the predictive fraud model using the fraud event parameters of previous fraudulent events undertaken in a plurality of accounts, wherein the previous fraudulent events are events suspected of having been conducted by the fraudster; and
generating the predictive fraud model includes generating a joint probability distribution that includes the plurality of fraud components, wherein the plurality of fraud components includes a plurality of fraud probability distribution functions that represent the fraud event parameters, wherein the fraud event parameters are observable fraud parameters collected during the previous fraudulent events.

Abstract
Systems and methods generate a risk score for an account event. The systems and methods automatically generate a causal model corresponding to a user, wherein the model estimates components of the causal model using event parameters of a previous event undertaken by the user in an account of the user. The systems and methods predict expected behavior of the user during a next event in the account using the causal model. Predicting the expected behavior of the user includes generating expected event parameters of the next event. The systems and methods use a predictive fraud model to generate fraud event parameters. Generation of the fraud event parameters assumes a fraudster is conducting the next event, wherein the fraudster is any person other than the user. The systems and methods generate a risk score of the next event to indicate the relative likelihood the future event is performed by the user.
