Case Study: Cheonan City Hall achieves enhanced citizen data privacy with Thales CipherTrust Transparent Encryption

Cheonan City Hall enhances public privacy security using CipherTrust Transparent Encryption

Cheonan City Hall, the municipal government serving about 660,000 residents in South Korea, needed to protect citizens’ sensitive data (resident registration numbers, addresses and phone numbers) for a COVID‑19 emergency aid bulletin board launched on a tight timeline. To meet the requirement for real‑time, kernel‑level encryption that wouldn’t require code or database changes, they selected Thales’ CipherTrust Transparent Encryption.

Thales implemented CipherTrust Transparent Encryption to deliver transparent, high‑performance encryption of both structured and unstructured data without altering applications or workflows. The solution protected personal information on the emergency aid site, preserved application availability and compatibility with existing systems (including SAP HANA), supported compliance with Korea’s data‑protection rules, and benefits from Thales’ CC and FIPS 140‑2 certifications recognized by the Korean National Intelligence Service.
