Introduction

With rise in digital payment and alternative payments, payment fraud rates are also significantly increasing. To counter this evolving pattern of fraud while ensuring the quality and lower cost of operation, financial institutes and central market infrastructures should consider the following for building a next generation Fraud and Risk management.

  • Orchestration of Risk Score from multiple sources: Creating an intelligent orchestration framework to integrate scores from various fraud protecting measures such as Verification / Confirmation of Payee, Negative List match, Real time Transaction Score and identification of mule activities
  • Cloud Migration: Establishing an optimized data architecture to ensure scalability and performance while lowering the cost
  • Testing and Assurance: Implementing robust model validation and tuning to adapt to evolving fraud patterns.

State of the Art Risk Score Orchestration

Fraud detection requires a comprehensive and adaptive risk-scoring mechanism. An advanced Score Orchestration Framework seamlessly aggregates inputs from various sources to arrive at a business conclusion. The framework also enables operators to define custom weights for different inputs based on operational priorities.

  • VoP match Results: Integrated payee name matching scores.
  • Negative List Screening result: Real-time validation against aggregated and federated negative lists.
  • Transaction Scoring from models and rule engines
  • Mule Account activity identification

Verification of Payee with Partial Percentage-based Matching Scores

Payee verification is critical for mitigating fraud types such as Authorized Push Payment (APP) fraud. The requirement of partial percentage-based matching leverages multiple techniques:

  • Multicultural Naming Conventions: Variations in script, spelling, and naming orders.
  • Data Quality Issues: Typos, abbreviations, and inconsistent data entry practices.
  • Linguistic Diversity: Transliteration complexities, especially for non-Latin scripts.

Proven Techniques

  1. Phonetic Algorithms:
    • Double Metaphone: Handles multiple pronunciations.
    • Indic Soundex: Custom-designed for Indian languages.
    • Cologne Phonetic: Adapted for flexibility across scripts.
  2. Edit Distance Algorithms:
    • Levenshtein Distance: Effective for minor spelling variations.
    • Jaro-Winkler Distance: Prioritizes similarities at the beginning of names.
  3. Token-Based Matching:
    • TF-IDF: Weighs name components for more accurate matching.
    • N-Gram Matching: Breaks names into smaller units for granular comparisons.
  4. Fuzzy Matching:
    • FuzzyWuzzy: Approximate string matching.
    • RapidFuzz: Useful for large datasets.
  5. AI/ML Techniques:
    • Natural Language Processing (NLP): Models trained to understand patterns and variations in ethnic names.
    • Supervised Learning: Custom models trained on labelled datasets.
    • Word Embeddings: Word2Vec and BERT for semantic similarity comparison.
  6. Hybrid Approaches: Combining multiple algorithms such as Phonetic with Edit distance or Rule-based with Fuzzy matching ensures high accuracy.
