SPOC: A SECURE AND PRIVACY-PRESERVING OPPOTUNISTIC COMPUTING FRAMEWORK USING BLOCKCHAIN TECHNOLOGY

Abstract: Secure data sharing in the cloud can be a difficult challenge. There are lots of risks with keeping sensitive info in one place. But hey, blockchain technology seems like a really cool answer! It can make data safer, more reliable, and super clear in cloud systems. In this study, we’re suggesting a new way to share data safely in the cloud using blockchain. What’s interesting about blockchain is it’s decentralized & unchangeable. This means we can create records of data transactions that can't be tampered with. This builds trust and makes everyone accountable. We also use smart contracts to set who can see what, making sure only the right people get access while keeping private and confidential. By mixing blockchain with cloud computing, we create a strong clear setup for sharing data. This helps to reduce the chances of someone accessing the data without permission or messing with it. In experiments, we show that our approach works well for secure and trackable data sharing in cloud environments. Our results point to how blockchain can really boost data security and privacy in these systems. This could lead us toward better, more trustworthy ways to share data.
