Blockchain for secure multi-cloud storage

Abstract

Cloud computing was recognized as an essential technology in the storage of data due to its flexibility and expandability. However, the conventional cloud computing system was identified as having weaknesses that could lead to insecurity in the system through unauthorized access, leakage of information, and reliance on single points of control. On the other hand, the multicloud computing system was recognized as an alternative in the storage of information in various cloud computing environments. However, the system was identified as having presented a challenge in the security of information in the cloud computing environment. Thus, a new technology was introduced to ensure the security of information in the conventional cloud computing system. The new technology was identified as blockchain.
