Abstract | Thanks to advancements in smart mobile devices and social media platforms, sharing photos and experiences has significantly bridged the authors’ lives, allowing them to stay connected despite distance and other barriers. Most approaches to protect image visual privacy focus on encrypting or permuting image data, which generate unreadable image or highly distorted visual effect and therefore may not be in users best interest from both usage and perception perspectives. In this study, the authors propose secure JPEG transmorphing, a framework for protecting image visual privacy in a secure, reversible, and highly flexible and personalised manner. Secure JPEG transmorphing allows one to apply arbitrary regional visual manipulation on image regions of interests (ROIs), while secretly preserving the information about the original ROIs in application segments (APPn markers) of the visually obfuscated JPEG image. Objective and subjective experiments have been performed and results indicate that the proposed protection scheme provides near lossless image reconstruction, controllable level of file size expansion, good degree of privacy protection and especially better subjective pleasantness. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
