| Abstract | Group video-conferencing systems are routinely used in major corporations, hospitals and universities for meetings, tele-medicine and distance learning among participants from very distant locations. As the use of video-conferencing becomes widely prevalent, the privacy concern's raised by this technology becomes an important issue to be addressed. In this paper we propose a real-time privacy preserving video conferencing system which protects the visual and audio privacy of selected individuals. In our proposed system we differentiate between the general participants and private participants (PP) whose privacy needs to be protected. We further divide the private participants into two different categories and provide a varying level of privacy protection based on the requirements. Specifically, among private participants, we have Active Private Participants (APP) who interactively participate in the meeting and Passive Private Participants (PPP) who play a passive observatory role. The video and audio privacy of the APP are protected by obfuscating their visual information by simple black boxing and real-time pitch modification process respectively. For the PPP, we completely protect their privacy by continuously detecting their presence and erasing them with a real-time adaptive background replacement process. |

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.
