### **Shift to Real-Time Intervention**

The newly adopted system utilizes advanced AI algorithms to monitor transactions in real time. Under the new protocol, if a transfer is flagged as high-risk, the system automatically suspends the transaction and triggers a requirement for additional identity verification. This mechanism is designed to balance rigorous security with customer convenience, intervening only when potential fraud is detected.

### **Overcoming Legacy Limitations**

The adoption of "AI Zero Fraud" addresses the limitations of traditional "rule-based" security models, which rely on static, pre-defined criteria to approve or deny transactions. As financial crime syndicates employ increasingly sophisticated methods, these fixed rules often fail to recognize novel attack patterns.

LAC’s solution fuses cybersecurity expertise with deep learning capabilities. By analyzing historical transaction data and continuously ingesting the latest intelligence on criminal trends, the system evolves its detection logic. This allows it to identify irregular patterns that would typically evade standard rule-based filters.

### **Strategic Partnership**

Both au Jibun Bank and LAC have committed to a continued partnership aimed at refining countermeasures against cyber and financial crimes. The initiative is part of a broader effort to ensure a secure financial environment for depositors amidst a landscape of evolving digital threats.
