| Abstract | This paper presents a simple but resilient method to suppress copyright violations among the content uploaded onto peer-to-peer (P2P) video sharing services, and is especially designed for consumer generated media (CGM). Encryption is a good way to block the circulation of illegal content. However, if the encryption key is caught by a malicious node in the P2P network, the ``denial of deletion'' ability offered by this key may make it difficult to stop the circulation of the content. To solve this problem, we propose a method to divide the encryption key into partial keys using the secret sharing scheme, and allowing them to be distributed into different nodes. Different from existing commercial P2P content distribution systems, this system is more scalable because the keys are managed in a distributed fashion. Regardless of the size of the P2P network, the probability of the encryption key being illegally used after the deletion operation for the target content is less than 0.1 even when more than 10\% of the nodes are malicious. |

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.
