Timely login status control using mobile app

After a user logs into web server using a public personal computer or a mobile device such as mobile phone, the leakage of his personal information may occur because he often forgets to log out from web server. To prevent the leakage of the personal information instantaneously, we propose a new login status control method based on the connectivity of web servers and a single mobile application. The proposed method visualizes and timely controls login status information of a user. Thus, we can effectively preserve the user´s personal information from accidentally or illegally being affected by anonymous users.
