A Secure and Authorized Data De-duplication and Continuous Data Auditing

Computer Science

De-duplication eliminates redundant information segments from the data storage and reduces the scale of storage information. This is often significantly helpful in Cloud Storage wherever information is transferred to the storage target over WAN. De-duplication with Cloud Storage not solely reduces the space for storing needs, however conjointly reduces the information that’s transferred over the network leading to quicker and economic data protection operations. It raises problems about security, possession and data integrity. Recently, many de-duplication schemes are planned to unravel this downside by permitting every owner to share an equivalent cryptography key for equivalent information. However, most of the schemes suffer from security flaws, since they are doing not take into account the dynamic changes within the possession of outsourced information that occur often in a very sensible cloud storage service. The proposed system includes completely unique server-side de-duplication over encrypted information and server side continuous data auditing. It permits the cloud server to regulate access to outsourced information even once the possession changes dynamically by exploiting irregular oblique encoding and secure possession cluster key distribution. Along with the deduplication check, system also proposes an in-house continuous data auditing for data integrity check. The system performance is tested and it proves that the system is as efficient as the previous system and the extra feature of continuous auditing requires a negligible computation overhead.
