CONTROLLING ACCESS TO SECURED APPLICATION FEATURES USING CLIENT TRUST LEVELS Russian patent published in 2015 - IPC H04L9/32 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates voice messaging systems. Disclosed is an architecture which facilitates the conveyance of a trust level when the caller makes a call, the trust level being dependent on the state of the caller system. The call recipient receives notification of the trust level and can use this information in communication. A caller can authenticate the caller identity in different ways to a communication server. Based on that, the server can assign an appropriate server-verified trust level to the caller. Further, an unsecured telephone controller can indicate a lower client-side defined trust level. The server verified and client-side trust levels are then sent to the call recipient, where the call recipient determines whether to allow caller access to one or more secured features based on the feature values and the trust level assigned by the call recipient to access those features.

EFFECT: secure communication.
