Abstract Cloud computing has become ubiquitous in our daily lives in recent years. Data are the source of technology that is generated hugely by various sources. Big data is dealing with huge data volumes or complex data. The major concern in big data is security threats. Security concerns create a negative impact on the user on the aspect of trust. In big data still, security threats exist as commonly known as DDOS (Distributed-Denial-of-Service) attacks, data loss, Inadequate Data Backups, System Vulnerabilities, and Phishing as well as Social Engineering Attacks. In our work, we have taken the data loss and Inadequate Data… More >

Abstract Online file management systems enable cooperatively editing and sharing. However, due to the cost of communication and storage infrastructures, traditional online file management services, e.g., Google Drive and OneDrive, usually provide limited storage space and relatively low download speed for free users. To achieve better performance, ordinary users have to purchase their expensive services. Moreover, these file management systems are based on centralized architecture and bear the privacy leakage risk, because users’ personal files are stored and controlled by their servers. To address the above problems, we propose a peer-to-peer (P2P) file management system based on IPFS and Hyperledger Fabric,… More >

Abstract The underlying premise of peer-to-peer (P2P) systems is the trading of digital resources among individual peers to facilitate file sharing, distributed computing, storage, collaborative applications and multimedia streaming. So-called free-riders challenge the foundations of this system by consuming resources from other peers without offering any resources in return, hindering resource exchange among peers. Therefore, immense effort has been invested in discouraging free-riding and overcoming the ill effects of such unfair use of the system. However, previous efforts have all fallen short of effectively addressing free-riding behaviour in P2P networks. This paper proposes a novel approach based on utilising a credit… More >
