Abstract

Transparent caller name authentication is provided to authorized third parties by creating an Public Key Infrastructure (PKI) certificate chain. An owner of a registered caller name can authorize third parties to use the caller name by issuing a PKI sub-certificate to each authorized third party. An authenticated caller name displays the owner's name to the called party. Outsourcing and mobile employment is thereby facilitated, and called party confusion is reduced.
