Secure Calls and Caller ID Spoofing Countermeasures Towards building a Cyber Smart Societies

Caller Identification (CallerID) is a service provided by the service providers that enables the receiver of the call to know who is trying to call him. Now a days, the caller ID service is used by many public and private organizations to contact their customers in order to exchange private information for authentication purposes. The unified caller ID for all the outgoing series of call connections, establishes an initial chain of trust between the caller and the callee. However, an increasing trends is observed where faking/spoofing the callerID has become a common trend. Cyber criminals spoof their caller IDs in order to gain call pickup trust from the user and build on to that initial trust to steel user data over phones. The faked callerID can cause roamers to spread and panic among public too. It is also used to defame organizations and particular people. In this paper, we aim at analyzing the existing methods to prevent the callerID spoofing along with their shortcoming and propose the model for caller ID verification that might be used to verify the identity of the caller.
