| Abstract | Mobile phone users in Participatory sensing (PS) systems are requested to collect information from their nearby locations. To ensure accurate results this exercise is well ordered and coordinated with mobile objects assigned to collect data in each data collection point. The users location information should be concealed all the times. Several techniques in PS have been proposed recently to provide user privacy protection. These techniques ignore the fact that mobile users in most cases are not stationary but rather moving objects, characterized by inevitable time varying uncertainty changes. Besides, they do not treat each user as an individual with special privilege. Users have personalized privacy requirements whose violation by other peers results in unauthorized access of information hence a privacy intrusion. Techniques for predicting the locations of moving objects exist. However majority assume continuous objects move according to linear functions. In other words, they lack generality as moving objects may follow dynamic motion patterns in real life. In practical situation mobile phone users frequently move or join/leave the PS system. Mobile objects are points that change their locations i.e., geometric coordinates over time, which demand many frequent updates of locations. It is important to capture this dynamic aspects of mobile objects in PS systems. In this paper, we incorporate a new location update policy while maintaining location comprehensive protection both peer-wise and service provider for non linear motion pattern of mobile objects in PS systems. Experimental results show that our personalized privacy framework achieves high protection while supporting moving objects queries and/or data with cloaked locations. |

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.
