USE CASE

Objective

  • Quickly and accurately detect fraudulent alterations (eg, counterfeit, forged) in bank checks

  • Verify handwritten checks

Outcome

  • Reduced manual review of handwritten checks

  • Models that use OCR and deep learning to scan checks, process data and verify signatures

  • Leverage historical database of previously scanned checks, including those known to be fraudulent

  • Models that assign risk scores to scanned checks, flagging them as good, fraudulent or needing further review. 

  • Increased model accuracy of detection

Business Value

  • Save millions in annual fraud losses

  • Increased customer trust and improved customer experience

  • Human-in-the-loop approach that allows investigators to focus on only high-risk reviews, improving OPEX and customer experience

H2O's AI and Data Approaches

  • Create Computer Vision model and build custom recipes that will generate features/variables that will provide a probabilistic estimation of the check being fraud or not. 

    • Check stock validation (CSV) for counterfeit detection 

    • Automated signature verification (ASV) for forgery detection 

    • CAL/LAR discrepancy and payee name verification (PNV) for alteration detection 

  • Thresholding rules, flagging major variations in check stock and signatures which may indicate a potential fraudulent payment

    • Once reviewed, feedback is provided back to the system to validate a “good” or “bad” payment.

 

 

H2O AI App: Check Fraud Detection, built with H2O Wave, SDK Kit for Data Scientists, can perform:

  •         Data Preparation (Bank data, customer data, customer images(signatures, etc))
  • Unsupervised Machine Learning, Neural Network, Predictive Modelling

  • Users can tune multiple parameters such as Sampling Ratio, number of hidden layers, epochs, etc.

  • Input data - cheque scan/photo

  • Dashboard containing the following major features:

  • Flag whether there is a major variation in payment made.

  • Flag whether operator review is needed.

  • Good/bad payment.

  • Textual insights on explaining the prediction.

  • Probability of the cheque being fraudulent.

  • Automatic Signature Verification result, forged or not.

This app demonstrates the use of machine learning as part of an overall plan to minimize employee attrition. Users can view predictions of employee departure, forecast churn rates, and identify relevant factors contained in employee data.
