At the same time, medical data may be illegally copied and maliciously tampered with without authorization. Therefore, the copyright protection and integrity authentication of medical information are worthy of attention. In this paper, based on the wavelet packet and energy entropy, a new method of medical image authentication is designed. The proposed method uses the sliding window to measure the energy of the detail information. In the time\u2013frequency data distribution, the local details of the data are mined. The complexity of energy is quantitatively described to highlight the valuable information. Based on the energy weight, the local energy entropy is constructed and normalized. The adjusted entropy value is used as the feature vector of the authentication information. A series of experiments show that the authentication method has good robustness against shearing attacks, median filtering, contrast enhancement, brightness enhancement, salt-and-pepper noise, Gaussian noise, multiplicative noise, image rotation, scaling attacks, sharpening, JPEG compression, and other attacks.<\/jats:p>","DOI":"10.3390\/e24060798","type":"journal-article","created":{"date-parts":[[2022,6,10]],"date-time":"2022-06-10T00:22:39Z","timestamp":1654820559000},"page":"798","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Medical Image Authentication Method Based on the Wavelet Packet and Energy Entropy"],"prefix":"10.3390","volume":"24","author":[{"given":"Tiankai","family":"Sun","sequence":"first","affiliation":[{"name":"Faculty of Electronic Information and Electrical Engineering, Dalian University of Technology, Dalian 116024, China"},{"name":"School of Information and Electrical Engineering, Xuzhou University of Technology, Xuzhou 221008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xingyuan","family":"Wang","sequence":"additional","affiliation":[{"name":"Faculty of Electronic Information and Electrical Engineering, Dalian University of Technology, Dalian 116024, China"},{"name":"School of Information Science and Technology, Dalian Maritime University, Dalian 116026, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kejun","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Information and Electrical Engineering, Xuzhou University of Technology, Xuzhou 221008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daihong","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Information and Electrical Engineering, Xuzhou University of Technology, Xuzhou 221008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Da","family":"Lin","sequence":"additional","affiliation":[{"name":"School of Information and Electrical Engineering, Xuzhou University of Technology, Xuzhou 221008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xunguang","family":"Jv","sequence":"additional","affiliation":[{"name":"School of Information and Electrical Engineering, Xuzhou University of Technology, Xuzhou 221008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin","family":"Ding","sequence":"additional","affiliation":[{"name":"School of Information and Electrical Engineering, Xuzhou University of Technology, Xuzhou 221008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weidong","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Information and Electrical Engineering, Xuzhou University of Technology, Xuzhou 221008, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,8]]},"reference":[{"key":"ref_1","first-page":"30165","article-title":"Watermarking techniques for medical data authentication: A survey","volume":"13","author":"Ashima","year":"2020","journal-title":"Multimed.
