US Patent 7475422 Securing internet browser-based email system through session management

One embodiment provides a process which will limit multiple active sessions of the same e-mail account to be active in multiple computers. Moreover, this embodiment allows the user of the email system to query the active session on the network with the ability to disable the active session in order to have the ability to open a new session from the user's present location. The process is done by querying a session database to find the state of the e-mail account if the first login attempt fails because of another open session. These safeguards are introduced to prevent multiple login sessions to an Internet Browser based email service for given login credentials.
