Enhancing the Data Storage Security in Cloud Computing With Cryptography Security Principles

The number of cloud users and the amount of sensitive data on cloud is increasing massively, so there is a serious need to provide security to the data stored in cloud. Cloud computing allows the user to store the massive amount of data in cloud and to make use of it on demand. One of the greatest challenges in cloud is data security. Since there is a serious security issue in cloud, users are more concerned about the sensitive data, which they store in cloud. Thus to implement the strong security to the data stored in cloud, we implement AES algorithm to provide confidentiality of data. Third party auditor (TPA) and Merkle Hash tree are used to provide integrity of the data. The scheme steganography is used, thereby hiding the sensitive data within the images. All these techniques are collaborated together, to implement strong security to the issues made to the data, which we store in cloud.
