Cloud in Blockchain Technologies

Abstract

Cloud computing and blockchain technology have become essential ideas in the field of IT, providing new ways to handle data. Cloud computing offers internet-based access to computing resources like servers and storage, while blockchain guarantees the accountability and immutability of data transactions with its distributed ledger system. Combining these technologies can enhance organizations' capabilities in data security and management. Businesses can utilize scalable infrastructure on cloud platforms by implementing blockchain technology, eliminating the need for large investments in physical resources. This integration improves the ability to access blockchain networks, making interactions easier across different locations and devices. Additionally, it enhances data security and privacy measures by enabling encrypted connections and strong authentication methods in cloud-based blockchain systems. Yet, obstacles remain in guaranteeing the authenticity and protection of information kept in multi-cloud settings, requiring effective authentication measures. To tackle these difficulties, this article presents a method for verifying data integrity in multi-cloud storage using blockchain technology, utilizing the decentralized aspect of blockchain to improve transparency and security. The plan automates verification procedures through smart contracts and cryptographic hashing, allowing for integrity checks at both a general and specific level across multiple Cloud Service Providers (CSPs). The proposed scheme has its effectiveness and reliability validated through theoretical analysis and experimental results, highlighting its potential to improve the security and efficiency of multi-cloud storage systems.
