Comparative Image Analysis of Chest X-RAY Image Encryption using Symmetric and Asymmetric Key Encryption Algorithms

Assuring the medicinal data is very important for protecting the patient’s privacy and their trust in the team. Prohibited access to confidential medicinal data gives rise to privacy breaches, healthcare scams, and improper health treatment. The technique that is suggested offers an opportunity for the encryption of chest scan images. The approach makes use of a multilayer encryption mechanism that contains a hashing layer, a digital signature layer, and the final encryption layer. The utilization of multiple algorithms for the layers mentioned above is analyzed and contrasted. For the encryption of an image, two algorithms are used which are AES and DES. For creating a digital signature, RSA and DSS are utilized. For all the three methods mentioned, RSA Key Encryption and SHA-256 hash algorithm are been frequently used. As for the evaluation metrics for the three approaches, time and space complexities are computed. The methods mentioned above prove the CIA triad which is confidentiality, Integrity, and authentication of the chest X-ray images. The most effective approach proves to be AES image encryption with RSA digital signature as it takes a short amount of time to decrypt.
