Artificial Intelligence Based Fake or Fraud Phone Calls Detection

Abstract

Technology and fraud strategies have made fraudulent phone call detection more complex, from manual monitoring and basic rule-based systems to AI-driven solutions. Rule-based algorithms dominated fraud detection systems before AI. These algorithms identified previously false patterns. A rule may indicate calls from countries with high phone fraud rates or calls made to many recipients 
quickly. Static Blacklist Dependence Known fake numbers were tracked using static blacklists. These manually updated lists automatically blocked or flagged calls from these numbers. For instance, a phone number that consistently committed fraud would be blacklisted. Automatically block or review future calls from that number.
