ABSTRACT
Cloud storage enables users to remotely store data and enjoy on-demand high quality cloud applications.
Though the benefits are clear outsourced data posses new security risks towards the correctness of the data in cloud.
To achieve a secure and dependable cloud storage service this project proposes a flexible distributed storage integrity auditing mechanism.
The proposed design allows users to audit the cloud storage with very lightweight communication and computation cost.
The testing application is designed using Microsoft Visual Studio .Net 2005 as front end and MS-SQL Server 2000 is used as back end database .
EXISTING SYSTEM
Techniques used can be useful to ensure the storage correctness without having users possessing data .
Researchers have also proposed distributed protocols for ensuring storage correctness across multiple servers to peers.
Since none of the distributed schemes are aware of dynamic data operations ,applicability in cloud data storage can be drastically limited.
Schemes focus on static or archival data. Hence capabilities of handling dynamic data remains unclear which limits full applicability in cloud storage scenarios.
DISADVANTAGES:
Dynamic data operations are not considered.
All the security threats cannot be addressed.
Traditional cryptographic primitives cannot be directly adopted.
Security aspects in data are risk.
Verification of correct data storage in the cloud must be conducted without explicit knowledge.
PROPOSED SYSTEM
An effective and flexible distributed scheme is proposed with explicit dynamic data support to ensure the correctness of users data in cloud.
Some part of the data is encrypted in the cloud storage with a symmetric key encryption.
To check the data in cloud storage is safe the sample data is fetched from cloud storage and decrypted.
Every user is provided with a strong authentication mechanism.
