Instruments and tools to extract knowledge and value from large collections of data are now available and enable new industries, business models, and jobs. However, the current data market is asymmetric and prevents companies from competing fairly. On the one hand, only very specialized digital organizations can manage complex data technologies such as Artificial Intelligence and obtain great benefits from third-party data at a very reduced cost. On the other hand, datasets are produced by regular companies as valueless sub-products that assume great costs. These companies have no mechanisms to negotiate a fair distribution of the benefits derived from their industrial data, which are often transferred for free. Therefore, new digital data-driven marketplaces must be enabled to facilitate fair data trading among all industrial agents. In this paper, we propose a blockchain-enabled solution to monetize industrial data. Industries can upload their data to an Inter-Planetary File System (IPFS) using a web interface, where the data are randomized through a privacy-preserving algorithm. In parallel, a blockchain network creates a Non-Fungible Token (NFT) to represent the dataset. So, only the NFT owner can obtain the required seed to derandomize and extract all data from the IPFS. Data trading is then represented by NFT trading and is based on fungible tokens, so it is easier to adapt prices to the real economy. Auctions and purchases are also managed through a common web interface. Experimental validation based on a pilot deployment is conducted. The results show a significant improvement in the data transactions and quality of experience of industrial agents.<\/jats:p>","DOI":"10.3390\/computers13040104","type":"journal-article","created":{"date-parts":[[2024,4,18]],"date-time":"2024-04-18T10:30:52Z","timestamp":1713436252000},"page":"104","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Using Privacy-Preserving Algorithms and Blockchain Tokens to Monetize Industrial Data in Digital Marketplaces"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7815-5924","authenticated-orcid":false,"given":"Borja","family":"Bordel S\u00e1nchez","sequence":"first","affiliation":[{"name":"Departamento de Sistemas Inform\u00e1ticos, E.T.S.I. de Sistemas Inform\u00e1ticos, Universidad Polit\u00e9cnica de Madrid, C\/Alan Turing, s\/n, 28031 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1183-9579","authenticated-orcid":false,"given":"Ram\u00f3n","family":"Alcarria","sequence":"additional","affiliation":[{"name":"Departamento de Sistemas Inform\u00e1ticos, E.T.S.I. de Sistemas Inform\u00e1ticos, Universidad Polit\u00e9cnica de Madrid, C\/Alan Turing, s\/n, 28031 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Latif","family":"Ladid","sequence":"additional","affiliation":[{"name":"Interdisciplinary Centre for Security, Reliability and Trust, University of Luxembourg, 4365 Esch-sur-Alzette, Luxembourg"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1534-6250","authenticated-orcid":false,"given":"Aurel","family":"Machalek","sequence":"additional","affiliation":[{"name":"Interdisciplinary Centre for Security, Reliability and Trust, University of Luxembourg, 4365 Esch-sur-Alzette, Luxembourg"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6480","DOI":"10.1287\/mnsc.2021.3986","article-title":"Knowledge accumulation, privacy, and growth in a data economy","volume":"67","author":"Cong","year":"2021","journal-title":"Manag.
