The proposed scheme generates an image watermark by using discrete cosine transform (DCT) and hides the watermark in the spatial pixels for image authentication and tamper detection. The hiding operator used in this paper is very simple in a mobile environment allowing high-speed authentication using a low-power mobile device. The quality of the stego-image and the recovered image becomes excellent as a result of the proposed scheme.<\/jats:p>","DOI":"10.3390\/sym10010013","type":"journal-article","created":{"date-parts":[[2018,1,3]],"date-time":"2018-01-03T12:00:06Z","timestamp":1514980806000},"page":"13","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["An Effective Authentication Scheme Using DCT for Mobile Devices"],"prefix":"10.3390","volume":"10","author":[{"given":"Chin-Chen","family":"Chang","sequence":"first","affiliation":[{"name":"Department of Information Engineering and Computer Science, Feng Chia University, Taichung 40724, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7305-4622","authenticated-orcid":false,"given":"Tzu-Chuen","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Information Management, Chaoyang University of Technology, Taichung 41349, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhao-Hua","family":"Zhu","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, National Huaqiao University, Xiamen 361021, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hui","family":"Tian","sequence":"additional","affiliation":[{"name":"College of Computer Science and Technology, National Huaqiao University, Xiamen 361021, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,1,2]]},"reference":[{"key":"ref_1","unstructured":"Tirkel, A.Z., Rankin, G.A., Van Schyndel, R.M., Ho, W.J., Mee, N.R.A., and Osborne, C.F.
