Data Securing of Patients in Cloud Computing Using A Combination of SHA256 and MD5

Patient data archiving in a medical institution is a relatively critical asset. If the data are managed by irresponsible parties, it will be risky both for the patients and the institutions. Therefore, data securing of patients are required to prevent negative impacts. The method in this study uses a prototype cycle, in making patient registration applications online. The technique used in this study is a combination of MD5 and SHA256 to be optimized for the data sent from database to the users, so that the encryption results in concise filing and timing.
