However, the regions of interest (ROI) are always some irregular parts, such as the face and the eyes. Assuming the bulk data in transmission without being damaged, we propose a chaotic image encryption algorithm for ROI. ROI with irregular shapes are chosen and detected arbitrarily. Then the chaos-based image encryption algorithm with scrambling, S-box and diffusion parts is used to encrypt the ROI. Further, the whole image is compressed with Huffman coding. At last, a message authentication code (MAC) of the compressed image is generated based on chaotic maps. The simulation results show that the encryption algorithm has a good security level and can resist various attacks. Moreover, the compression method improves the storage and transmission efficiency to some extent, and the MAC ensures the integrity of the transmission data.<\/jats:p>","DOI":"10.1142\/s0218127416501935","type":"journal-article","created":{"date-parts":[[2016,10,27]],"date-time":"2016-10-27T23:08:14Z","timestamp":1477609694000},"page":"1650193","source":"Crossref","is-referenced-by-count":31,"title":["Chaotic Image Encryption of Regions of Interest"],"prefix":"10.1142","volume":"26","author":[{"given":"Di","family":"Xiao","sequence":"first","affiliation":[{"name":"Key Laboratory of Dependable Service Computing in Cyber Physical Society of Ministry of Education, College of Computer Science, Chongqing University, Chongqing 400044, P.
