Lawmaker Demands Right to Renew Leaked CI After Data Breaches

Opposition lawmaker Kim Sun-min calls for CI system reform at a parliamentary audit; commission chair Kim Jong-chul promises to review legal changes and renewal measures.

At a parliamentary audit of the National Assembly's Science, ICT, Broadcasting and Communications Committee, opposition lawmaker Kim Sun-min called for reforms to the linked information (CI) system, arguing that users should have the right to renew their CI if it is leaked. Kim cited the fact that a leaked CI never changes value, leaving affected individuals unable to protect themselves.

Kim also said that the Korea Communications and Media Commission (방미통위) is reviewing a validity period of 1 to 3 years for CI. Commission chair Kim Jong-chul responded that the commission is working on legislative improvements to address the CI problem and will also review renewal measures, according to ZDNet Korea.

Background

The debate follows a series of data breaches. CI was leaked in last year's Lotte Card breach, and on October 10, 2026, chair Kim Jong-chul mentioned pushing for a renewal system in connection with a Shinhan Bank CI leak. In April 2026, the commission fined Lotte Card for inadequate safety measures for personal identification numbers, and the Lotte Card incident brought forward the separation of resident registration numbers and CI by 4 months; that separation requirement was reported in June 2026 to take effect on January 1 next year.
