Fraud Detection

Fraud detection systems use machine learning and data analytics to identify suspicious transactions, accounts, or behaviors that indicate financial crime or unauthorized activity. In enterprise AI governance, fraud detection models require careful oversight to prevent algorithmic bias that could unfairly flag certain customer segments while missing sophisticated fraud schemes. Regulatory compliance demands transparency in how these systems make decisions, regular audits of their accuracy across demographic groups, and clear processes for human review when high-value transactions are flagged.
