Radio Frequency Identification (RFID) provides easier identification of the data object. This process involves tagging an object to a transmitter which emits a burst of information including identification of the tag. The identification process and the various components involved in the transmission, identification and receiving of the radio waves. However, RFID suffer from data leaks, apart from this, it experiences severe security threats such as, Privacy, Security and Integrity. In this paper, Confidential Synchronized Anti-Tag Cloning (CSATC) is introduced, a method to secure the tag from being cloned with the help of back end server. The CSATC is validated using Efficient and Reliable Trivial RFID Authentication (ERTRA) algorithm. In ERTRA algorithm, implementation of Synchronous Secrets Method (SSM) and Optimal Trivial RFID Authentication Protocol (O-TRAP) are considered. This method efficiently processes the algorithm and, the privacy and security problem can be solved.
