A Study on Data Integrity and Storage Efficiency Services in Cloud

These days, cloud computing is producinglarge volume of repository area and enormous parallel computing at adequate cost. Extreme volum e of data is being reserved in the cloud since the cloud computing is becoming more popular. In spite of, the aggressive rise of growing amount of the data has erected mo re number of novel challenges. In this task, the issue w ith integrity auditing and the secure deduplication exist on cloud data is studied. Especially, the target is on gaining both the data integrity and deduplication which is existing in cloud, two secure systems is designed called Se cCloud and SecCloud+. The SecCloud will offer an audit ing stuff with the alimentation of a Map Reduce cloud that aid the clients in order to provoke the data tags before they are being uploaded as well as to audit the integrity of data that is being reserved in cloud.
