| Abstract | This paper presents a novel stream-level joint layered coding scheme for unified reliable and secure media transmission over wireless networks. The proposed scheme simultaneously protects both compressed media content and the authentication data from wireless channel impairments. Therefore, the media quality degradation incurred by both channel noise and authentication constraints can be minimized. With a prior knowledge of source coding and channel coding, the proposed joint system integrates authentication into the media error protection components to ensure 100% effective verification probability, i.e. every source decodable media unit is authenticable. In particular, by utilizing the contextual relationship, such as coding dependency and content importance between media slices for authentication hash appending, the proposed scheme generates an extremely low authentication overhead. The proposed authentication scheme is fundamentally different from many existing systems that consider the problem of authenticating media content separately from the other operations in the media transmission system. Under this joint layered coding framework, an optimal rate allocation algorithm for source coding, channel coding and media authentication is developed to guarantee the end-to-end media quality. Experiment results on JPEG 2000 images validate the proposed scheme and demonstrate that the performance of the proposed approach is approaching its upper bound, in which case no authentication is applied to the media stream. |

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.
