ABSTRACT In today’s world security in cloud computing technology is a developing area. For cloud computing technology services, it is a matter to discuss. Encryption of data is required before it is kept in reserve on the cloud. ECC algorithm is being used instead of known and popularized RSA for data encryption for providing security services. Because of its additional benefits with regards to less memory usage, smaller key size of encrypted data and lower central processing unit time. We had proposed framework to secure patients data. Main drawback of existing system is Patient had to carry reports in hard copy, so whatever prescriptions given by doctors will be encrypted and will be uploaded on cloud . If any one wants to download specific patients report , they should have secret key , so only authentic user can access record. Keywords: Elliptic Curve Cryptography, Rivest-Shamir Adleman.
