KakaoBank has applied an AI-based financial fraud detection model to its abnormal transaction detection system, analyzing customer behavior before and after transactions. The \"sequence detection model\" uses an attention mechanism to assess transaction order, time gaps between actions and device-change patterns, and can spot pauses and resumptions in activity.
