Abstract: Systems for issuing authentication challenges based on fraud initiation requests are provided. The system may calculate a fraud risk level based on a fraud initiating request comprising identity-based data. In response to the fraud risk level indicating a risk of fraud, the system may determine an authentication challenge type. The system may cause a display on the client device of an authentication challenge and verify an authentication challenge response received from a client device.

Abstract: Systems for issuing authentication challenges based on fraud initiation requests are provided. The system may calculate a fraud risk level based on a fraud initiating request comprising identity-based data. In response to the fraud risk level indicating a risk of fraud, the system may generate an authentication challenge based on an authentication challenge type and an authentication challenge delivery channel. The system may transmit the authentication challenge and receive back an authentication challenge response. The system may verify the authentication challenge response and generate an authentication outcome based on the verification.

Abstract: Systems and methods for processing payments using a dynamic security code are provided. A dynamic security code generator may generate one or more dynamic security codes and transmit the plurality of dynamic security codes to a portable consumer device. The portable consumer device may display the dynamic security code. A merchant may transmit a transaction request to the account authorization system including the dynamic security code in a card security code field. The account authorization system may compare the transaction account number and dynamic security code in the transaction request to a transaction account number and dynamic security code stored in a database. The account authorization system may transmit an authorization message to the merchant.

Abstract: A system for generating an identity theft score is disclosed. The system may identify consumers who have experienced identity theft during a historical time period, generate an identity theft risk model based upon the plurality of consumers who have experienced identity theft, and generate an identity theft score for an individual consumer based upon the identity theft risk model and data associated with the individual consumer. The identity theft risk model may comprise a regression model, and the identity theft score may represent a probability that the individual consumer will experience identity theft during a future time period.
