Detection of call is one of the key process this generation for customers to look over and find the details and information of the caller. It is easy to identify a caller by the method of caller detection. But the calls that come from an IP based computer system through a scheme of VoIP it is difficult to find or detect a call where mostly attackers use this kind of technique. This caller detection process is also used by many banks in order to take the confirmation of the customer. This detection can be done by using a smartphone by installing an appropriate application in the mobile or by using service providers that offer caller ID spoofing. The upgrade of old hardware is very costly, and there is no mechanism available to end users where there is no storage of information and it also very difficult to locate the physical location of the attacker. The main drawback is that it is more complex when it is considered in the real world. In this article, we consider an appropriate solution named as Passive IP Trace-back to overcome the challenges in deployment in caller id detection. PIT is a kind of technique where we can find out the history of the attacker through which we can consider that a specific person is trying to attack the victim. PIT exploits the path back-scatter messages to find the location of the attacker. The scheme of PIT is used as an efficient software for computers to validate their effectiveness in the detection of spoofing attacks.
