Is that really you?: an approach to assure identity without revealing real-name online

Abstract Identity poisoning by fake-named account is caused not only by identity theft but also by valid accounts with impersonated screen-names. From users' perspective, screen-name is an identifier of other users without obtaining any credential information. To prove the originality of a user without revealing identifier information, we focused on linkability, an element of online identity. Not only the extent of linkability but also its direction assures the originality. We assumed that the existence of bi-directional link(s) among two or more entities shows the tight relationship thus there is possibility of being identified as the same users'. As a result of our experiment, on Twitter, identified pairs are obviously filtered from suspicious pairs only based on direction of links.

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).

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.
