| Abstract | The emerging location based services have brought forth a privacy risk where users expose their location information. Most of the existing solutions preserve location privacy relying on a trusted anonymizer, which may not exist in real situation. Several peer-to-peer approaches are proposed, but these techniques require large-scale data storage and communication, and they cannot provide up-to-date context information to users. To address this issue, we propose a novel method JointCache to preserve location privacy by confusing nearby users' paths. Using this technique, users do not need to buffer context information of a large area and they only need to transfer little information to each other for cooperation. We use simulation to compare JointCache with the traditional path confusion, the results show that our technique solves the same place same time problem, and achieves higher anonymity even in a low user density situation. |

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.
