Enhancing Security and Privacy in Cloud-Based Medical Data Systems using AES Cryptography and Digital Envelopes

The integration of healthcare data storage and management within cloud systems has revolutionized accessibility and administration in the medical field. This paper, proposes a security framework for medical data over the cloud. The medical data can be encrypted using AES algorithm. Preprocessing and data aggregation are pivotal in creating protected training files sent to the cloud. Cloud processing utilizes an SVM algorithm for data analysis, enabling informed medical decisions. The study findings affirm the system's robustness and security in handling diverse security and privacy concerns linked with cloud-based medical data. By employing digital envelopes and encryption standards, this system offers a dependable and efficient approach to accessing and processing healthcare information.
