The objective of the present invention is to provide a method for a biometric authentication electronic signature service by using an instant messenger, which enables confidentiality, integrity, non-repudiation, and user authentication. The method includes the step of binarizing an electronic transaction approval request process and an electronic signature execution process in a single service system, thereby preventing electronic transaction forgery/falsification by memory hacking or the like using intrinsic personal information electronically, fundamentally blocking user authentication and electronic transaction payment approval in various hackings and illegal duplication uses, more reinforcing security without additional authentication of two or more channels, and improving user convenience and operation efficiency of a web service provider. |
