Abstract

Caller ID validation system and methods are provided. When a call is placed over a communication network, a validation system receives the call signaling, and processes the call signaling to identify originating node information in the call signaling. The originating node information is inserted by the communication network when handling the call and pertains to a network node that originates the call into the network. The validation system also processes the call signaling to identify caller ID information for the call. The validation system then processes the originating node information and the caller ID information to determine whether the call originated from the originating node. If the call did originate from the originating node, then the validation system determines that the caller ID information is valid.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a system and method for authenticating caller ID information to protect a called party from caller ID spoofing. Background technique [0002] Service providers typically provide caller ID services to their subscribers. Caller ID service is an intelligent network service that provides caller ID information, such as the calling party's directory number and name, to the called party's telephone equipment during the ring signal. Communication networks typically provide caller ID information between the first and second rings of a call. The called party's telephone equipment then displays the caller ID information to the called party. [0003] One problem with today's caller ID services is that the caller ID information may not be valid, this is often referred to as caller ID spoofing. Caller ID spoofing is the practice of causing a communication network to display on a c...
