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.

A method of providing transparent caller name authentication for authorized third party callers, comprising:
- receiving a PKI sub-certificate at equipment for authenticating the caller name when a call to a called party is initiated;
- examining the PKI sub-certificate to determine if it was issued by a caller name owner who registered the caller name in a registry to which the equipment for authenticating the caller name has been subscribed;
- and
- establishing an authentication dialogue with a sender of the PKI sub-certificate to authenticate the caller name.
A method of providing transparent caller name authentication for authorized third party callers, comprising issuing a PKI certificate to an owner of a caller name, logo or other means of caller identification, the PKI certificate permitting the owner of the PKI certificate to sign PKI sub-certificates that bear the caller name and to issue one of the PKI sub-certificates to a third party selected by the owner to place caller name authenticated calls on behalf of the owner.
Outsourced service supplier call equipment for providing transparent caller name authentication to called parties called on behalf of companies that outsource tasks to the outsourced service supplier, comprising:
- a PKI certificate selector that is used to select a PKI sub-certificate signed by a one of the companies that outsourced a task to the outsource service provider;
- and
- call control equipment for establishing a call to a called party associated with the task, and for sending the selected PKI sub-certificate to a call authentication application that authenticates the caller name on behalf of the called party.
Call center call equipment for providing transparent caller name authentication to a called party called on behalf of a company that outsourced tasks to the call center, comprising:
- a PKI certificate selector that is used to select a PKI sub-certificate signed by the company that outsourced a task to the call center;
- call control equipment for establishing a call to a called party associated with the outsourced task;
- and
- caller name authentication equipment for sending the selected PKI sub-certificate to a call authentication application that authenticates the caller name on behalf of the called party in order to convey a caller name authentication message to the called party.
