  • Automatic user authentication and identification for mobile instant messaging application
    Patent number: 8607317
    Abstract: Automatic identification and authentication of a user of a mobile application entails receiving from the wireless communications device a unique device identifier and an e-mail address corresponding to the wireless communications device, associating a registration identifier with the unique device identifier and the e-mail address, generating an authentication token, and communicating the authentication token and the registration identifier to the wireless communications device. This technology obviates the need for the user to remember and enter a user ID and password to access backed-up application data on a server. This is particularly useful for instant messaging applications, e.g. PIN messaging, in which the unique device identifier is used to identify the user and is also the transport address. Once registered, the user who has switched to a new device or has wiped his existing device, can restore contacts or other application data from the server based on the registration identifier.
