Advanced Blockchain Techniques for Secure data Sharing through Ownership Authentication in Cloud Environment

Blockchain Technology has established itself as an effective solution to warrant the transparency and security of data sharing in Cloud Computing. The objective of this research paper is to analyze the possibilities of using Blockchain Technology and upgrading the security of the cloud-based data sharing by utilizing multi-factor authentication. We introduce an improved system using smart contracts, token-based security and smartphone authentication to build a secure framework. This system could eliminate nearly all unauthorized cloud computing access - drastically reducing security breaches. A literature survey was performed to investigate the identified limitations and challenges in cloud security and data sharing. Then we develop and offer an efficient and better scalable solution for protecting sensitive and important information in this digitally growing landscape.
