Nonghyup Bank Secures Patent for Financial Sector's First AI-Based Credit Audit System

NH Nonghyup Bank announced on December 3 that its proprietary 'AI Auditor' and 'EW-AR (Early Warning Advanced Ratio)' technologies have been registered with the Korean Intellectual Property Office as the first case in the financial sector to formalize an artificial intelligence (AI)-based credit audit process.

These two technologies are core modules of the 'AI-based Credit Audit System' that Nonghyup Bank implemented this year. The 'AI Auditor' quantifies the judgment of audit personnel using AI, automating the process of selecting and evaluating high-quality borrowers, thereby enhancing work accuracy and efficiency. In addition, 'EW-AR' is a specialized indicator that incorporates the latest machine learning (ML) techniques, strengthening early warning capabilities to quickly predict and identify potentially insolvent borrowers, thus improving the detection performance for credit risk.

With this patent, Nonghyup Bank plans to contribute to the development of an AI risk management ecosystem throughout the financial sector. In particular, the bank intends to begin developing 'AI Auditor 2.0' next year, aiming to complete an agentic AI-based automated audit and monitoring system.

Kang Taeyoung, President of Nonghyup Bank, stated, "The AI-based credit audit system will go beyond simple prevention of insolvency to support customer growth through data-driven proactive risk management," adding, "We will expand the application of AI technology to all major work areas to enhance the accuracy and speed of risk management."
