However, the practical application of EEG-based biometrics is not currently widespread and there are some challenges to its implementation. Nowadays, the evaluation of a biometric system is user driven. Usability is one of the concerning issues that determine the success of the system. The basic elements of the usability of a biometric system are effectiveness, efficiency and user satisfaction. Apart from the mandatory consideration of the biometric system\u2019s performance, users also need an easy-to-use and easy-to-learn authentication system. Thus, to satisfy these user requirements, this paper proposes a reasonable acquisition period and employs a consumer-grade EEG device to authenticate an individual to identify the performances of two acquisition protocols: eyes-closed (EC) and visual stimulation. A self-collected database of eight subjects was utilized in the analysis. The recording process was divided into two sessions, which were the morning and afternoon sessions. In each session, the subject was requested to perform two different tasks: EC and visual stimulation. The pairwise correlation of the preprocessed EEG signals of each electrode channel was determined and a feature vector was formed. Support vector machine (SVM) was then used for classification purposes. In the performance analysis, promising results were obtained, where EC protocol achieved an accuracy performance of 83.70\u201396.42% while visual stimulation protocol attained an accuracy performance of 87.64\u201399.06%. These results have demonstrated the feasibility and reliability of our acquisition protocols with consumer-grade EEG devices.<\/jats:p>","DOI":"10.1186\/s40708-021-00142-4","type":"journal-article","created":{"date-parts":[[2021,10,11]],"date-time":"2021-10-11T14:07:33Z","timestamp":1633961253000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Person authentication based on eye-closed and visual stimulation using EEG signals"],"prefix":"10.1186","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1367-3226","authenticated-orcid":false,"given":"Hui Yen","family":"Yap","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun-Huoy","family":"Choo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zeratul Izzah","family":"Mohd Yusoh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wee How","family":"Khoh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,10,11]]},"reference":[{"issue":"2","key":"142_CR1","doi-asserted-by":"publisher","first-page":"213","DOI":"10.1016\/j.eij.2015.06.002","volume":"16","author":"SN Abdulkader","year":"2015","unstructured":"Abdulkader SN, Atia A, Mostafa MSM (2015) Brain computer interfacing: applications and challenges.
