In this paper, we propose a decentralized digital rights management model of spatial data, which can provide a novel way of solving the existing copyright management problem or other problems in spatial data infrastructure for data sharing. An Ethereum smart contract is used in this model to realize spatial data digital rights management function. The InterPlanetary File System is utilized as external data storage for storing spatial data in the decentralized file system to avoid data destruction that is caused by a single point of failure. There is no central server in the model architecture, which has a completely decentralized nature and it makes spatial data rights management not dependent on third-party trust institutions. We designed three spatial data copyright management algorithms, developed a prototype system to implement and test the model, used the smart contract security verification tool to check code vulnerabilities, and, finally, discussed the usability, scalability, efficiency, performance, and security of the proposed model. The result indicates that the proposed model not only has diversified functions of copyright management compared with previous studies on the blockchain-based digital rights management, but it can also solve the existing problems in traditional spatial data infrastructure for data sharing due to its characteristics of complete decentralization, mass orientation, immediacy, and high security.<\/jats:p>","DOI":"10.3390\/ijgi9020084","type":"journal-article","created":{"date-parts":[[2020,2,3]],"date-time":"2020-02-03T11:28:31Z","timestamp":1580729311000},"page":"84","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["A Decentralized Model for Spatial Data Digital Rights Management"],"prefix":"10.3390","volume":"9","author":[{"given":"Yun","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Geography and Tourism, Anhui Normal University, Wuhu 241000, China"},{"name":"Engineering Technology Research Center of Resources Environment and GIS, Wuhu 241000, China"},{"name":"Laboratory of Natural Disaster Process and Prevention Research of Anhui Province, Wuhu 241000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9507-5579","authenticated-orcid":false,"given":"Zhi","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Geography and Tourism, Anhui Normal University, Wuhu 241000, China"},{"name":"Engineering Technology Research Center of Resources Environment and GIS, Wuhu 241000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Geography and Tourism, Anhui Normal University, Wuhu 241000, China"},{"name":"Engineering Technology Research Center of Resources Environment and GIS, Wuhu 241000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yue","family":"Ding","sequence":"additional","affiliation":[{"name":"School of Geography and Tourism, Anhui Normal University, Wuhu 241000, China"},{"name":"Engineering Technology Research Center of Resources Environment and GIS, Wuhu 241000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao","family":"He","sequence":"additional","affiliation":[{"name":"School of Geography and Tourism, Anhui Normal University, Wuhu 241000, China"},{"name":"Engineering Technology Research Center of Resources Environment and GIS, Wuhu 241000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaosheng","family":"Xia","sequence":"additional","affiliation":[{"name":"School of Geography and Tourism, Anhui Normal University, Wuhu 241000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunhua","family":"Li","sequence":"additional","affiliation":[{"name":"School of Resources and Environmental Engineering, Anhui University, Hefei 230601, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,1]]},"reference":[{"key":"ref_1","first-page":"168","article-title":"Inside an Environmental Data Archive WWW Site","volume":"Volume 2","author":"Denzer","year":"1997","journal-title":"Environmental Software Systems"},{"key":"ref_2","unstructured":"Wang, J.L., Zhu, Y.Q., and Xie, C.J.
