Starting October, communication service firms are required to have internal management procedures requiring the approval of an official responsible for personal information management when it comes to printing clients' personal information or duplicating it onto a diskette. The Ministry of Information and Communication put on notice a management criterion for the protection of clients' personal information by communication service providers such as key communication operators, Internet shopping malls and Internet portal sites. After a six-month guidance period, the ministry will enforce the criterion in October, with a fine of up to 10 million won for companies failing to come up with adequate protective arrangements.
