Apparatus for unified authentication using representative application

摘要

The present invention relates to an integrated authentication method using a representative application, a system and a device therefor, and in particular, by performing authentication of another application by sharing authentication information using a representative application among a plurality of applications installed in one terminal, applications Under the assumption that a trust relationship is established, authentication information can be shared within a single device through a representative application. In addition, it refers to registering an account with reference to a representative application, and through this, it is possible to implement a Single Sing On (SSO) authentication method in a mobile environment. In addition, through a representative application, it can be executed only by reference between applications without an internal browser, which is not limited by various operating systems. In addition, the SSO authentication method can increase the transparency and reliability of management, reduce costs, and increase efficiency. In other words, increase the efficiency of user ID or password management, use of other systems without separate login, support authentication, decrease administrator's password inquiry, reduce re-entry for user login / shutdown / reconnection, and reporting function for user's access information Etc. are possible.
