A High Secure Medical Image Storing and Sharing in Cloud Environment Using Hex Code Cryptography Method-Secure Genius

Recent healthcare sectors require delivering the heterogeneous collected works of medical data to the healthcare authorities with less consumption of time and cost. Cloud computing when used in Healthcare sector provide essential infrastructure which decrease the cost of storing, processing and improvement with improved competence and quality. However, security and privacy issue is a strong barrier for users to become accustomed into Cloud Computing systems. The medical data in the healthcare includes the text files, scan images, DNA reports, X-rays, and discharge summaries etc., which are considered as the patients' personal data. Furthermore secure atmosphere is needed for storing and transferring the Medical data in cloud. The global medium for serving confidentiality of transmitted data is Cryptography. To conquer the downside of usual encryption algorithms such as computation time for large files, storage issues and quality of encryption, this paper introduces a new technology called Hex code oriented encryption method. The proposed work triggers two level of encryption for achieving higher grade of security. First level is to encrypt the data by assigning hex codes to each character and for the generation of combination of secret key RSA and Enhanced ElGamal Algorithm is designed. Second level is that the generated key is converted into hex code and is added with the encrypted file which in turn provides strong encryption and high efficiency. Thereby, this work provides an application to encrypt the data using hex codes and RSA and Enhanced ElGamal to generate secret key as the password in turn to decrypt the file.
