Abstract
This paper aims to design an encrypted secure system for processing sensitive healthcare information through AES encryption and homomorphic encryption with TenSEAL to authenticate health data on cloud storage platforms including Firebase. The necessity for this research stems from the rising concerns of healthcare information security and risks in addition to the rising obligatory compliance standards across the global such as HIPAA and GDPR. This study assesses effectiveness, security and acceptability of these encryption techniques for actual use in healthcare organizations. Principal conclusions are that AES encryption became rather safe and efficient algorithm for data protection but it has a certain loss in performance especially with the increase of block and key size. Homomorphic encryption though useful in data privacy during data processing adds massive computational cost. Integration with Firebase for the cloud storage was possible and viable due to security and faster data access. Overall, users expressed satisfaction on the system but there is a problem on how to effectively teach users on encryption. Taking into consideration the results of the research, the authors assume that encryption systems can become a useful instrument in the protection of healthcare data, however, to make them efficient and useful for all those healthcare organizations that need protection of sensitive data in real time, further development is still required. In future work, there will be improvements to the techniques of homomorphic encryption, improving the key management, and the implementation of the system on existing healthcare platforms.
