THE CHALLENGE
Automate the detection of financial fraud in consumer credit, incorporating new data sources into anti-fraud processes.
THE CONTEXT
New anti-fraud solutions
Agos, a leading financial company in the consumer credit sector, has faced a series of challenges related to the identification and prevention of financial fraud. With the ever-increasing threat of fraudsters using false documents or stolen identities to obtain illicit loans, the manual analysis of identity cards remains a point of vulnerability.
To counter these threats, the company has adopted an innovative and automated approach that integrates new information sources and advanced data analysis techniques. Agos was thus able to strengthen its system for the detection and prevention of financial fraud and to protect the integrity of the company and its customers.
THE SOLUTION
Identify counterfeit documents with synthetic data and ML
To respond to Agos' need to detect fraud, Target Reply has proposed an innovative approach that effectively combines elements of Computer Vision (through the use of Convolutional Neural Networks), Machine Learning algorithms and synthetic data in different phases of the data analysis process. Convolutional Neural Networks, due to their considerable efficiency in image processing, enable the extraction of visual characteristics used as input for Machine Learning-based classification algorithms. This automation facilitates document analysis for funding requests and ensures an effective identification of counterfeit identity cards. At the same time, the integration of synthetic data has resulted in a significant improvement in the quality and quantity of the available data, helping to increase the overall performance of the model.

HOW DID WE DO IT
The key role of synthetic data for a large and balanced dataset
As part of the project, synthetic data was used to effectively address the challenges related to fraud detection.
Detecting fraud requires a large and balanced training dataset. The conventional approach faced limitations due to the lack of authentic data and the need to safeguard privacy. Leveraging synthetic data generated through Generative AI models has overcome these challenges, has made it possible to use highly realistic artificial information that accurately reproduces the characteristics of counterfeit cards. This use of synthetic data has improved the ability of the model based on Convolutional Neural Networks (CNN) to detect fraud with high accuracy.
Particular attention has been given to the explainability of the analysis model. The ability to understand the system's decision-making process, namely how counterfeit identity cards are classified and which document attributes influence those decisions, is crucial for instilling greater confidence in Agos regarding the choices made by the system.
