However, traditional data trading models are plagued by critical flaws in fairness, security, privacy and regulation. To tackle the above issues, we first proposed a distributed industrial data trading architecture based on blockchain and cloud for multiple data owners. Subsequently, we realized implemented distributed identity management by the distributed verifiable credentials scheme that possesses the desirable properties, i.e., selective disclosure, multi-show unlinkability, threshold traceability, and public verifiability. Finally, we presented a fair trading mechanism without trusted third parties based on smart contracts, and we employed blockchain and multi-signature to ensure data integrity during data storage and trading. The security and performance analysis shows that our proposal is feasible for sensitive data trading for multiple data owners and provides a useful exploration for future industrial data trading and management.<\/jats:p>","DOI":"10.1186\/s13677-023-00530-7","type":"journal-article","created":{"date-parts":[[2024,2,2]],"date-time":"2024-02-02T10:02:38Z","timestamp":1706868158000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Blockchain-cloud privacy-enhanced distributed industrial data trading based on verifiable credentials"],"prefix":"10.1186","volume":"13","author":[{"given":"Junli","family":"Fang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xian","family":"Guo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rong","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ye","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,2,2]]},"reference":[{"issue":"3","key":"530_CR1","doi-asserted-by":"publisher","first-page":"1504","DOI":"10.1109\/comst.2017.2691349","volume":"19","author":"JQ Li","year":"2017","unstructured":"Li JQ, Yu FR, Deng GQ, Luo CW, Ming Z, Yan Q (2017) Industrial internet: a survey on the enabling technologies, applications, and challenges.
