Abstract: Cloud computing is an emerging technology that offers computing, storage, and software as a service to IT organisations and individuals. To prevent cloud resources from external threats, data leakage, and various attacks, security controls, and technological safeguards should be offered to the data centres of the cloud. This paper proposes a novel approach known as the multi-cloud database (MCDB) which uses multiple cloud service providers (CSP) instead of a single CSP. For this purpose, a Shamir's secret sharing algorithm and a sequential triple modular redundancy (TMR) technique are implemented to improve the reliability and offer enhanced security to the MCDB. The proposed model is compared with one single cloud (SPORC) and four multi-cloud models (DepSky, HAIL, RACS, MCDB without TMR) in terms of reliability, integrity, confidentiality, availability, and security. The maximum reliability, integrity, confidentiality, availability, and security values obtained for the proposed model were 100%, 99%, 99%, 97%, and 99%.
