Original Abstract Submitted
Methods and systems for secure caller identification are described herein. In one implementation, when a phone call from a caller is received, a home network may mark a caller ID as trustable in a trusted flag if the caller ID can be verified. The home network may further forward the caller ID and a replica of the flag to a next hop entity until the next hop is the callee. The network on each hop may further verify the caller ID based on a trust relationship between the network and a prior network. In another implementation, the home network of the caller may send a caller ID token (CIT) associated with the caller and send a replica of CIT to a serving network of the callee through one or more networks. The serving network may verify the replica of CIT to determine whether the caller ID is trustable.
