Visual voicemail client authentication
View Patent ↗Visual voicemail enables a user to view a list of voicemail messages and caller information, and select which messages to hear. Currently, a handset accesses visual voicemail using a web interface over a point-to-point network connection with an intermediary gateway. The gateway initiates requests to the voicemail platform on behalf of the handset using a single generic password. There is no direct authentication between the handset client and the voicemail platform. In an embodiment of the invention, the handset requests a password from the voicemail platform using the web interface. The voicemail platform sends a password to the handset via a Short Message Service text message, which is an inherently secure means of communication. The handset then uses the password to request voicemail data from the voicemail platform via the web interface.
1. Computer-readable media having computer-executable instructions embodied thereon that, when executed, cause a handset to perform a method of maintaining a password for accessing a visual-voicemail server, the method comprising:
receiving at said handset a message that includes a password for accessing voicemail, wherein said message is received from said visual-voicemail server via a Short Message Service (SMS), wherein said password is received in response to a password request sent from said handset to said visual-voicemail server via a point-to-point data connection;
storing said password;
sending from said handset, to said visual-voicemail server, a request for voicemail data, wherein said request includes said password, and wherein sending said request for voicemail data includes communicating with a voicemail-abstraction server; and
receiving at said handset said voicemail data from said visual-voicemail server.
2. The media of claim 1 , wherein said password is generated by said visual-voicemail server.
3. The media of claim 1 , wherein said request for said voicemail data is sent using a web-services interface.
4. The media of claim 1 , wherein said voicemail data is received via a web-services interface.
5. Computer-readable media having computer-executable instructions embodied thereon that, when executed, cause a handset to perform a method of maintaining a password for accessing a visual-voicemail server, the method comprising:
receiving at said handset a message that includes a password for accessing voicemail, wherein said password is a new password received in response to a password request sent from said handset, wherein said password request is sent periodically based on an interval selected by a user of said mobile device, and wherein said message is received from said visual-voicemail server via a Short Message Service (SMS);
storing said password;
sending from said handset, to said visual-voicemail server, a request for voicemail data, wherein said request includes said password; and
receiving at said handset said voicemail data from said visual-voicemail server.
6. The media of claim 5 , wherein said password is generated by said visual-voicemail server.
7. The media of claim 5 , wherein said request for said voicemail data is sent using a web-services interface.
8. The media of claim 5 , wherein said voicemail data is received via a web-services interface.
9. The media of claim 5 , wherein sending said request for voicemail data includes communicating with a voicemail-abstraction server.
