ENSURING DATA INTEGRITY IN CLOUD DATA STORAGE
Gaurav Pachauri, Subhash Chand Gupta · 2014
Cloud Computing is the newest fast growing technology in the current era due to its easy manageable services. Cloud computing provides on demand network oriented services to centrally organised computing resources with great efficiency and minimal efforts. As cloud computing achieved through network access, there arises a lot of security concerns related to cloud computing. All data resides in centralized cloud data storage. This cannot be completely trustworthy .Cloud computing paradigm brings a lot of security challenges which are still to be resolved. The main concern is about the Integrity of data in cloud data storage. If a cloud service provider modify or delete our data from the storage due to some private problem then in that case how will we be able to verify that our data is modified or how will we be able to generate proofs that our data has been altered. These all are very serious issues related to Cloud computing .So in this paper we have discussed the current security mechanism to ensure the integrity of data in cloud storage. We have suggested a third party auditing mechanism to verify the integrity of data periodically without accessing the whole data. In prior mechanism to ensure the remote data integrity, there are also issues as some do not support public audibility and some do not support dynamic data operations. In this paper we have discussed all aspects of current mechanism as well as the third party involvement which resolves both public audibility and dynamic data operations.
