Truth discovery Mechanism: A decentralized blockchain approach

Computer Engineering

In the period of big data, the data about a similar article gathered from various sources is definitely gets conflict. This wonder inspires the need of truth disclosure, which expects to naturally locate the genuine case among numerous clashing cases. Truth discovery is point of botch as the nodes in the network functions independently. As the block-chain lacks support for on-chain data confidentiality, we utilize the privacy-preserving solution and incorporate it with blockchain for privacy protection. We implement the framework with the Ethereum blockchain and demonstrate it`s performance in which the process of extracting accurate data from the large data sets that are combined from the crowd-sourcing applications. Most of existing publicly supporting frameworks depend on central servers, which are dependent upon the powerless nesses of conventional trust-based model. They are also vulnerable to distributed denial of service stacks due to malicious users involvement. The decentralized model along with block chain ensures data privacy and reliable truth discovery process and overcomes single
