To address this issue, a novel thumbnail-preserving encryption scheme is proposed based on a hybrid of decimal and binary pixel values in three pixel groups, utilizing the excellent dynamic characteristics of a generalized coupled logistic map. Theoretically, it is proved that the core algorithm of this scheme is sum-preserving. Experimentally, it is demonstrated that this scheme not only excels in efficiency and resistance to attacks, effectively safeguarding image privacy, but also retains high-quality thumbnails after encryption, achieving both objectives of image privacy protection and visual usability. <\/jats:p>","DOI":"10.1142\/s0218127424501931","type":"journal-article","created":{"date-parts":[[2024,11,6]],"date-time":"2024-11-06T15:10:22Z","timestamp":1730905822000},"source":"Crossref","is-referenced-by-count":1,"title":["Thumbnail-Preserving Encryption Based on Binary\u2013Decimal Hybrid and a Generalized Coupled Logistic Map"],"prefix":"10.1142","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-5964-4764","authenticated-orcid":false,"given":"Yuanlin","family":"Chen","sequence":"first","affiliation":[{"name":"School of Mathematics and Statistics, Sichuan University of Science and Engineering, Zigong, Sichuan 643000, P.
