Browser session privacy lock

Techniques are shown for executing a web browser on a client computing device and requesting access to applications available from a hosting server over a network in communication with the client device. The web browser stores authorization credentials for accessing designated applications available from the hosting server in a lockbox. A message received at the web browser provides instructions to lock all designated applications by rendering at least partially blanked-out or partially obscured visual displays for the designated applications, with no viewing of, access to, or operation on selected data within the designated applications permitted, while the locked designated applications remain logged-in. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
