More recently, any technology can't be stated perfect until it's totally free of any vulnerability. There are many technologies has grown in day-to-day life that offer online data storage, being able to access the data from anywhere whenever you want and most importantly they provide on the internet use of any software. Cloud computing is a paradigm providing you with data storage and also it possesses different services on lease contract facility. In recent years all the medical data is stored as well as managed in online worldwide. The data can be utilized by medical professional, patients for their understanding, government authorities and insurance companies etc. The medical related data can be protected in the form of Electronic Health Records (EHR) which is available online at any time. It contains data like ray x images, scan images, therapy procedure, medical prescription, patient information. All of this kind of sensitive records facing the problem is where it can be stored securely and who can access as well as view the data. To resolve this, we design a secure cloud storage for healthcare data by using a Hybrid cryptographic technique. Within this, the data are encrypted through symmetric algorithm and keys are encrypted using an asymmetric algorithm. The performance evaluation, as well as security of proposed method, was measured and compared to an existing technique. The results clearly show that our method provides better security than any other hybrid algorithms.
