The proposed parametric binary tree labeling scheme is used to label a plaintext image\u2019s pixels as two different categories, regular pixels and irregular pixels, through a symmetric or asymmetric process. Regular pixels are only utilized for secret payload embedding whereas irregular pixels are not utilized. The proposed technique efficiently exploits intra-block correlation, based on the prediction mean of the block by symmetry or asymmetry. Further, the proposed method utilizes blocks that are selected for their pixel correlation rather than exploiting all the blocks for secret payload embedding. In addition, the proposed scheme enhances the encryption performance by employing standard encryption techniques, unlike other block based reversible data hiding in encrypted images. Experimental results show that the proposed technique maximizes the embedding rate in comparison to state-of-the-art reversible data hiding in encrypted images, while preserving privacy of the original contents.<\/jats:p>","DOI":"10.3390\/sym13061072","type":"journal-article","created":{"date-parts":[[2021,6,16]],"date-time":"2021-06-16T21:58:32Z","timestamp":1623880712000},"page":"1072","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Intra-Block Correlation Based Reversible Data Hiding in Encrypted Images Using Parametric Binary Tree Labeling"],"prefix":"10.3390","volume":"13","author":[{"given":"Arun Kumar","family":"Rai","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, Indian Institute of Technology (Indian School of Mines), Dhanbad 826004, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neeraj","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, Nagarjuna College of Engineering and Technology, Bengaluru 562164, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajeev","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Delhi Technological University, Delhi 110042, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hari","family":"Om","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Indian Institute of Technology (Indian School of Mines), Dhanbad 826004, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5250-9074","authenticated-orcid":false,"given":"Satish","family":"Chand","sequence":"additional","affiliation":[{"name":"School of Computer and System Sciences, Jawaharlal Nehru University, Delhi 110067, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0662-8355","authenticated-orcid":false,"given":"Ki-Hyun","family":"Jung","sequence":"additional","affiliation":[{"name":"Department of Cyber Security, Kyungil University, Kyeongbuk 38424, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"677","DOI":"10.1109\/TCC.2017.2702586","article-title":"A State-of-the-Art Review","volume":"7","author":"Pahl","year":"2019","journal-title":"IEEE Trans.
