<p>The present invention relates to a system for providing log in of an application using authentication sharing, which is capable of logging in to another application using a logged application. More specifically, the system comprises: a user terminal in which a first application and a second application are installed and a user is allowed to log in to the first application; and a service server which receives, from the user terminal, a token of the first application; a signature of the first application; a consumer key of the second application and a signature of the second application whereby the user is allowed to log in to the second application using user information identified from the received token of the first application. [Reference numerals] (1) Consumer key + signature; (101) First application (logged application); (102) Second application (not logged application); (120) Service server; (2) Token A + signature A + consumer key B + signature B; (3,4) Token B + token password; (AA,BB,CC,DD) Yes; (S301) Discussion A effective?; (S302) Signature A effective?; (S303) Consumer key B effective?; (S304) Signature B effective?; (S305) Identify a user and allow the user to log in a second application, using the token A; (S306) Generate the token B and a token password</p> |
