Synthetic Data of Transactions for Inmediate Loans' Fraud
Description
This dataset contains realistic synthetic data generated with a commercial tool, taking as an input a real dataset of CaixaBank’s express loans for a timespan of 18 months. The real dataset was tagged in order to identify the confirmed and tentative fraud cases in which a fraudster has impersonate the client to claim that type of loan and steal client’s funds. The dataset includes several indicators that help fraud analysts to identify any suspicious behaviour of the user that could imply an impersonation or misbehaviour. This dataset was used in INFINITECH H2020 project to build an AI model for cyberfraud prevention in this type of operations, which are especially critical because of two factors. First, it is type of loan, an operation in which the fraudster can steal money that the client does not really own, so it can be stolen even from clients without funds on their accounts. Second, it is an operation that was offered to the clients to speed up the process of acquiring loans of small amounts. The fraudsters can take profit of that and proceed faster as well stealing that money. The detail of the data fields included in the dataset is specified in the table below.
