Cloud computing provides users to remotely store their data and high quality of cloud applications by reducing risk of local hardware and software management.To protect data from outsourced leakages, we propose a flexible distributed storage integrity auditing mechanism (FDSIAM), these mechanism utilizes the homomorphic tokens (MAC address and secret key), blocking and unblocking factors and distributed erasurecoded data.Suppose user is out of station we can generate alert information to mobile devices, if any attacker attacks the data immediate message has been given to particular user through mobiles.The auditing results not only ensure storage correctness, but simultaneously identifies misbehaving server.Our proposed design provides very lightweight communication and computation cost for users to audit the data.Cloud data are dynamic in nature, our design supports secure and efficient dynamic operations on outsourced leakages, including block insertion, modification, append and delete operations.Our experimental results are highly efficient and secure against malicious data modification attack, server colluding attacks and byzantine failures.
