The National Assembly will launch an investigation into the massive data leak that struck three card firms and affected millions of card holders earlier this month.
At a joint press briefing on Tuesday, the floor leaders of the ruling Saenuri and main opposition Democratic Party announced they had agreed to investigate the leak and draw up countermeasures.
The investigation will aim to uncover the reasons for the leak at the three credit card firms -- KB Kookmin, Nonghyup and Lotte.
Specifically, it will target the firms' systems for securing data and sharing information with their affiliates.
The investigation will be handled by the parliamentary policy committee and will begin in February.
Separate hearings on legislation against data theft will be conducted by other standing committees.
The list of countermeasures could include improvements to data management systems and legislation against the recurrence of similar incidents.
Korea's financial regulators are currently auditing the three credit card firms in question and will start auditing six others as a follow-up measure beginning in February.
This will be the first time the financial watchdog has audited all of the nation's credit card firms.
Prosecutors announced earlier this month that the personal and financial data of 20 million credit card holders and tens of millions of bank customers had been leaked, prompting fears that the information could be used in scams, as well as concerns about the size and scope of data collection in Korea.
