A system and method for caller identification, named certified caller ID (CCID) provides an enhancement to existing calling line identification services by providing the terminating end of a telephone call with a cryptographically-certified identity of the caller, rather than the identity associated with the calling telephone line. Advantageously, in the operation of CCID, the caller's identity is authenticated by a token, such as a smart card or other integrated circuit device which is capable of executing a cryptographic authentication protocol, optionally in conjunction with a Personal Identification Number (PIN) or biometric confirmation. Beneficially, CCID works in conjunction with several associated Customer Local Area Signalling Services (CLASS), e.g. Selective Call Acceptance, Selective Call Forwarding and Distinctive Ring to provide special call treatment based on the identity of the caller.
