Fintech, which means IT based financial service, gets a lot of focus from many people. Korea government also wants to promote fintech industry growth, and improves financial regulations which prevent fintech growth. Especially Korea government radically mitigated electronic authorization regulations. However, personal data protection regulations also need to be mitigated. Compared with U.S., Korea personal data protection acts strictly restrict collection and use of consumer personal data.

In order to promote fintech industry, Korea personal data protection regulations need to be mitigated.
