The present invention relates to a system and method for image-based authentication, wherein user authentication is performed by the preregistered mobile communication terminal of a user transmitting, to an authentication server, an authentication key corresponding to an authentication image. In the image-based authentication system according to the present invention, a system for authenticating an end entity comprises a computer device for performing a first authentication through communication with an online service system and a mobile communication terminal for performing a second authentication, and includes: a unit for registering a mobile communication terminal, which registers the end entity information needed for the second authentication, and a mobile communication terminal matching the end entity information; a unit for generating an authentication key, which generates a second authentication key issued to the end entity in which the first authentication is completed; a unit for generating an authentication image, which generates an authentication image corresponding to the generated second authentication key and provides the authentication image for display on the computer device of the end entity in which the first authentication is completed through the online service system; and a unit for verifying authentication, which verifies the second authentication key received from the activated mobile communication terminal after activating the mobile communication terminal registered in the end entity in which the first authentication is completed. |
