Versatile critical applications are using cloud environment. Critical applications require reliable cloud environment such as scientific research, financial and safety critical applications. Transient errors occur when energetic neutron particles from space and alpha particles from packaging materials hit the integrated circuit (IC). It may cause timeout fault and temporary inaccessibility of services. These errors may change the state of memory bits or may alter the register file. These single bit, multiple bits and burst bits errors may cause either service unavailability or produce invalid results. To reduce the effect of such errors, a fault tolerant mechanism is essential. Some of the popular fault tolerant techniques are parity checking, two dimensional parity checking, hamming codes, checksum and cyclic redundancy check. Most of these schemes are either hardware based or software based. In this paper, we propose a software based effective fault tolerant (EFT) technique. The EFT scheme can detect any type of error on data and it's one's complement using XNOR operation. The proposed EFT scheme covers 99.9% of errors.
