Abstract
A voice call system and a method and apparatus for identifying a voice caller are disclosed. The system includes a call originator apparatusand a called party apparatus. At least one trusted user identity is formed at the call originator apparatus, ideally in a trusted platform moduleconfigured according to a Trusted Computing Platform Alliance (TCPA) specification. The called party apparatuschecks the trusted user identity when establishing a new voice call. Advantageously, an identity of the voice caller using the call originator apparatus is confirmed in a reliable and trustworthy manner, even when the voice call is transported over an inherently insecure medium, e.g. an open computing system like the internet. Preferred embodiments of the invention use IP telephony, such as SIP (session initiation protocol) or H.323 standard voice telephony.
