Abstract
Cloud Computing gains users to store their data into the cloud as the remotest manner so that they can be comforted from the trouble of local data save and maintenance. The user loses the control of his remotely located data. This feature has many security challenges such as the authority and integrity of data. One of the significant concerns that require to be addressed is to assure the user of the integrity i.e. rightness of his data in the cloud. Continuously, the user cannot access to cloud’s data directly. So, the cloud must provide a technique for the user to ensure if the integrity of his data is protected or is compromised. In this paper, we propose the use of encrypted data integrity by presenting the feature extraction of handwriting signature in a modern encryption scheme that preserves the integrity of data in cloud server. Any prohibited data modification, removal, or addition can be detected by cloud user. Additionally, our proposed scheme presents a proof of data integrity in the cloud which the user can know the truth of his data in the cloud server. We employ user’s handwritten signature to secure and integrate his data in cloud server. Extensive security and performance analyses view that our proposed scheme has highly efficient and provably secure. In addition, the performance time decreases and the compensation ratio of data integrity is increases.
