Abstract |
|
|
| In cloud storage system, security of data stored by the owner in the cloud is exposed to risk toward the integrity of data like unauthorized data modification, server failure, misbehaving server. The proposed system guarantees security by auditing which is performed by the owner or by hiring third- party auditor who does the inspection on behalf of the owner. To preserve privacy from the third- party auditor, the complete user data blocks is not derived; instead certain signature techniques are used. It works efficiently for dynamic data operation like update, appends, etc. and also for distributed storage by using auditing mechanism which involves homomorphic authenticator and erasure code. It is a lightweight process and it has very low computation cost. The performance evaluation and security analysis show that the system works efficiently for dynamic data which ensure integrity of the data with low cost and low overheads.
