| Abstract | Privacy-protecting technology is essential in this surveillance society. The applications of cameras widely vary, e.g., crime surveillance, monitoring of an environment, and marketing. Furthermore, the scale of surveillance systems is predicted to become more diverse (from home area networks to wide area networks) due to the decrease in size and price of cameras. Therefore, a simple privacy protection system that does not require central servers or large databases is needed. Scrambling private information in a captured image can be a solution to simplifying a system. We propose an image-scrambling method for bitmap and JPEG formatted images to private information. Our method enables access control by providing keys to authorized individuals. They cannot view private information that they do not have permission to access. The image's format is retained; therefore, no special viewer is necessary in display-only console. Experimental results suggest that scramble level can be controlled linearly by using parameters (three for JPEG formatted image, and one for bitmap image). We also developed a demo system for this method and confirm that this method can be applied to embedded systems such as those equipped with surveillance cameras. |

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.
