Cloud computing is open and unrestricted, reliability of data and delivery became the prime indicators. Cloud became a much bigger trend in the business and networking world. This also provides flexibility so it is very useful in a new generation of services and products. Normally, the data is stored and shared to multiple users. The data can easily lose, dropped or corrupted due to software fault or network failures. There are lot of technologies are used to allow public verifiers to audit cloud data without retrieving entire data or file. Oruta is one of technology that uses ring signature, used to compute and verify metadata needs to audit the correctness of shared data in the block. In this paper, we propose a new mechanism that is improves the privacy of data that achieves traceability with data freshness.
