An Efficient Storage in the cloud &Secure HER Retrieval by using HECC

The sector of healthcare generates lot of data related to the health of patients, where large number of people enrols in hospital. It contains a large image and document data that needs to be processed over a different entity. Since the data is in the isolated form, unmanaged manner there is a need for the personal health records system that will ultimately holds up the factors affecting the data and provides a better managing capability. Indexing, secured transmission, Data minimization is always an issue which deals with encryption and decryption algorithms with different key sizes. With existing algorithm, time consumption to store and retrieve stored data is high as it involves MD5 algorithm. This paper gives an overall explanation of the storage of data in cloud where huge data plays a major role. Hence, an proposed algorithm containing compress storage, security along with fast as well as secure access is also presented in this paper. Improvement of Security and storage is done by Hyper-elliptic curve cryptography (HECC) with Asymmetric encryption technique, Hash function using secure Hashing algorithm (SHA-2) followed by Discrete Wavelet Transform (DWT) compression to minimize cloud space.
