Diagnosis by nail can effectively predict and prevent disease. Human nails have a high degree of uniqueness, and it can be used for biometric recognition. In this work, microscope sensor was used to capture the clear image and segment the lunula and nail plate effectively through image preprocessing. Fingernails\u2019 image is managed as the identity authentication. Histogram of oriented gradients and local binary patterns are used to capture the characteristic value. It uses support vector machine and random forest tree for classification. The performance of each feature extraction algorithm was analyzed for the two classifiers and the deep neural network algorithm was used comparatively. Furthermore, the security and privacy of the Internet of Things is still a challenge. This work uses the highly anonymous blockchain technology to effectively protect data privacy and manage each user\u2019s data through the blockchain, in which any change or manipulation can be recorded and tracked, and the data security is improved. Therefore, this article presents a nail analysis management system with the use of microscopy sensor and blockchain. <\/jats:p>","DOI":"10.1177\/1550147718767044","type":"journal-article","created":{"date-parts":[[2018,3,28]],"date-time":"2018-03-28T09:52:28Z","timestamp":1522230748000},"page":"155014771876704","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":48,"title":["Fingernail analysis management system using microscopy sensor and blockchain technology"],"prefix":"10.1177","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7395-556X","authenticated-orcid":false,"given":"Shih Hsiung","family":"Lee","sequence":"first","affiliation":[{"name":"Institute of Computer & Communication Engineering and Department of Electrical Engineering, National Cheng Kung University, Tainan, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chu Sing","family":"Yang","sequence":"additional","affiliation":[{"name":"Institute of Computer & Communication Engineering and Department of Electrical Engineering, National Cheng Kung University, Tainan, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2018,3,28]]},"reference":[{"key":"bibr1-1550147718767044","first-page":"343","volume-title":"Proceedings of the 5th international symposium on 2007 image and signal processing and analysis, ISPA 2007","author":"Chaikan P"},{"key":"bibr2-1550147718767044","volume-title":"Proceedings of the international conference on computer communication and informatics (ICCCI-2015)","author":"Devi MR"},{"key":"bibr3-1550147718767044","doi-asserted-by":"publisher","DOI":"10.1007\/s00296-010-1715-8"},{"key":"bibr4-1550147718767044","doi-asserted-by":"publisher","DOI":"10.1136\/ard.62.5.444"},{"key":"bibr5-1550147718767044","doi-asserted-by":"publisher","DOI":"10.1007\/s11045-012-0177-4"},{"key":"bibr6-1550147718767044","doi-asserted-by":"publisher","DOI":"10.1007\/s10067-009-1288-7"},{"key":"bibr7-1550147718767044","first-page":"271","volume-title":"Proceedings of the 2014 international conference on cyberworlds (CW)","author":"Sultana M"},{"key":"bibr8-1550147718767044","volume-title":"Proceedings of the 2016 international conference on emerging trends in engineering, technology and science (ICETETS)","author":"Easwaramoorthy S"},{"key":"bibr9-1550147718767044","volume-title":"Proceedings of the 2014 IEEE 3rd global conference on consumer electronics (GCCE)","author":"Fujishima N"},{"key":"bibr10-1550147718767044","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2014.11.008"},{"key":"bibr11-1550147718767044","first-page":"23","volume-title":"Proceedings of the 2013 IEEE security and privacy workshops (SPW)","author":"Chakravorty A"},{"key":"bibr13-1550147718767044","volume-title":"Proceedings of the 2017 IEEE international conference on pervasive computing and communications workshops (PerCom Workshops)","author":"Dorri A"},{"key":"bibr14-1550147718767044","volume-title":"Proceedings of the 2016 IEEE international conference on internet of things (iThings) and IEEE green computing and communications (GreenCom) and IEEE cyber, physical and social computing (CPSCom) and IEEE smart data (SmartData)","author":"Samaniego M"},{"key":"bibr15-1550147718767044","volume-title":"Proceedings of the 2017 19th international conference on advanced communication technology (ICACT)","author":"Huh S"},{"key":"bibr19-1550147718767044","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2016.2566339"},{"key":"bibr20-1550147718767044","volume-title":"Proceedings of the 2016 IEEE\/ACS 13th international conference of computer systems and applications (AICCSA)","author":"Conoscenti M"},{"key":"bibr21-1550147718767044","volume-title":"Proceedings of the 2016 IEEE international conference on computer and information technology (CIT)","author":"Samaniego M"},{"key":"bibr22-1550147718767044","volume-title":"Proceedings of the 2016 IEEE 18th international conference on high performance computing and communications IEEE 14th international conference on smart city;
