Abstract
There has been a rise in the amount of individuals storing and using data in multi-cloud hosting systems in recent years. Among the benefits it offers are the assurance of data safety, the avoidance of information corruption, and the prevention of unethical issues arising from suppliers. The hybrid approach presented in this project was designed with the goal of enhancing cloud data security and privacy. The hybrid approach makes use of a multi-cloud hosting setup. This hybrid methodology consists of two different parts. (A) an encryption layer that withstands security lapses and permits uninterrupted operation of the application. (b) The confidentiality and reliability of data stored in the cloud are enhanced by the use of encoding and decoding techniques via multi-cloud architecture. The use of encryption techniques improves data storage privacy and trustworthiness without sacrificing efficiency. For a range of medical datasets, approaches including hybrid encryption and multi-level encryption are used and compared with the privacy and security issues related to the hybrid approach. The hybrid approach outperforms existing multi-level encryption techniques like Twofish, ChaCha2-, Serpent, Camellia, and TripleDES in terms of performance. This holds throughout the amount of memory used, the time needed for encryption and decryption, and the overall time needed for authentication. The hybrid technique provided favorable results for the average accuracy measurements, the amount of memory utilized, and the time required for encryption and decryption.
