Case Study: Ajou University Hospital achieves secure patient data, regulatory compliance, and minimal performance impact with Oracle Advanced Security

Ajou University Medical Center Strengthens Security for Sensitive Data, Minimizes Performance Degradation, and Meets Regulatory Requirements

Ajou University Medical Center, a leading teaching hospital in Suwon, Korea, needed to strengthen protection of patients’ sensitive personal information and meet stringent national privacy regulations without disrupting clinical and research operations. After recent high-profile data breaches in Korea, the hospital sought a reliable, low-cost encryption approach that would avoid application changes, preserve system performance, and minimize downtime.

The center implemented Oracle Database with Oracle Advanced Security—supported by partner ATEC—to deliver transparent data encryption and selective redaction of sensitive fields. The solution provided regulatory compliance, preserved data types and formats, required no application modifications, kept CPU utilization below 50%, and limited encryption-related downtime to under two hours, all while reducing implementation cost and maintaining stable system performance.
