Abstract:
Data is a critical asset for any company, as well as for any individual as well, but it is also vulnerable to attack. In the last few years, we have seen an alarming increase in data breaches that have compromised millions of accounts and resulted in billions of dollars lost. But how do you protect something so sensitive? In response to this, we propose our Project. This project focuses on developing a Decentralized Cloud Storage to store and secure data. You don't access data simply specifying 'where it is' in Decentralised Cloud Storage. Instead, you define 'what it is'. Because data is dist

Abstract: Because of its accessibility and ease of use, cloud storage has become the most widely used type of storage on the market in recent years. However, the privacy and data security of cloud storage are at risk. The protection of data security and privacy is the main topic of this essay. We suggest a blockchain-based decentralised storage system. Since blockchain is a distributed peer-to-peer system, any processing node connected to the internet can join and build peers' networks, maximising resource usage. Blockchain protects data security.

Presently, the majority of IoT devices use cloud storage to store the data, however, cloud servers require large storage and high computation. Due to third party cloud service provider (CSP) interaction, the management of IoT data security fully depends on th

Abstract:
Blockchain technology has brought a new change in many sectors mainly through provision of decentralized transactional solutions and it is an open, continuously growing list of records, which is distributed and not controlled by centralized authorities. The current regulation is the first one of such kind because it encompasses payment, communication, registration, and monitoring of transactions between members, without the need to have a central authority to manage the needs of the organization. There are however, challenges, which persist for example in data storage and scalability. This pap

Abstract:
Cloud provides its users with different services. Every day during cloud computing, a great deal of data is generated. On the cloud servers, the data is being saved. A recovery tool should be created in case this data is lost from the server. One such setup is described in this consideration. The proposed approach would enable simultaneous data storage on the inaccessible server and the cloud server. The information is returned from the farther server when the key record is misplaced. Secret key security is ensured so that the authentication is secure and authorized by the user based on the at

Abstract:
The current distributed storage solutions are still concentrated in third-party storage service providers, and the stored data are concentrated in a few cloud servers, which inevitably brings the risk of data loss, leakage, and tampering, so it is imperative to study a distributed storage and decentralized storage system. How to maintain the consistency of data in a distributed environment has become a problem in building decentralized applications, until the emergence of blockchain technology, whose decentralized, non-tamperable, and traceable features can solve this problem well.

Abstract:
Outsourcing storage to the cloud can save storage costs and is commonly used in businesses. It should fulfill two major goals: storage efficiency and data confidentiality. Encrypted deduplication can achieve both goals via performing deduplication to eliminate the duplicate data within encrypted data. Traditional encrypted deduplication generates the encryption key on the client side, which poses a risk of offline brute-force cracking of the outsourced data. Server-aided encryption schemes have been proposed to strengthen the confidentiality of encrypted deduplication by distributing the encry

Abstract:
Cloud computing has revolutionized data storage and management; however, security and privacy concerns remain critical challenges. This paper explores the integration of blockchain technology to enhance data security in cloud environments. A decentralized approach ensures data integrity, authentication, and tamper resistance. The proposed framework leverages smart contracts to enforce access control policies efficiently. Simulation results indicate that our model significantly improves data security without compromising system performance.

Abstract:
The number of customers transferring information to cloud storage has grown significantly, with the rising prevalence of cloud computing. The rapidly rising data volume in the cloud, mostly on one side, is followed by a large replication of data. On the other hand, if there is a single duplicate copy of stored symmetrical information in the de-duplicate cloud backup the manipulation or lack of a single copy may cause untold failure. Thus, the deduplication of files and the auditing of credibility are extremely necessary and how they are achieved safely and effectively must be addressed in acad

Abstract:
cloud storage system, consisting of a collection of storage servers, provides long-term storage services over the Internet. Storing data in a third party’s cloud system causes serious concern over data confidentiality. General encryption schemes protect data confidentiality, but also limit the functionality of the storage system because a few operations are supported over encrypted data. Constructing a secure storage system that supports multiple functions is challenging when the storage system is distributed and has no central authority.

Although blockchain is excellent for decentralized transaction recording, it has certain drawbacks when it comes to storing big files or documents. Decentralized storage systems have been created to effectively manage greater volumes of data in order to address this problem. A distributed system called blockchain makes sure that transactions are safe and clear. To enhance data sharing, some strategies have looked into combining blockchain with other technologies. However, relying solely on blockchain technology for safe file sharing has drawbacks. In this study, we present a secure file-sharin
