Abstract
A method for initiating a security and billing feature request at the beginning or during an active telephone call. The telephone subscriber can select one of a plurality of security levels that may be required to ensure privacy during a call. Since each level of security is based on a different encryption and authentication algorithm, the levels of security can be incrementally priced. Thus, selecting an algorithm which is deemed to be very secure can be billed to the subscriber at a higher rate than an algorithm that is deemed to be less secure.
