Apparatus for unified authentication using representative application

摘要

The present invention relates to a method, a system, and a device for integrated authentication using a representative application. According to the present invention, authentication information using a representative application, which is one among a plurality of applications installed on a terminal, is shared for authentication of another application. As a result, authentication information sharing in one device is possible via the representative application on the assumption that an inter-application trust relationship is established. In addition, this means account registration referring to the representative application, and thus single-sing-on (SSO) authentication can be realized even in a mobile environment. In addition, this can be carried out simply by inter-application reference and even without an internal browser by means of the representative application, and thus this is not restricted by various operating systems. In addition, the SSO authentication results in management transparency and reliability enhancement, cost reduction, and efficiency enhancement. In other words, what can be provided include more efficient user ID or password management, use of another system without extra login, authentication support, less password inquiries to an administrator, less re-input for user login/ending/re-access, and a reporting function with respect to user access information.
