The objective of this study is to define a model of personal data validationin the context of decentralized systems. The distributed nature of Linked Data,through DBpedia, is integrated with Blockchain data storage in a conceptualmodel. This model is illustrated through multiple use cases that serve as proofsof concepts. We have constructed a set of rules for validating Linked Data andpropose to implement them in smart contracts to implement a decentraliseddata validator. A part of the conceptual workflow is implemented through aweb interface using Open BlockChain and DBpedia Spotlight.
