| Abstract | Analysis of contemporary web browser sessions for forensic purposes has one major challenge - that of distinguishing Internet events and sessions across multiple tabs. While some information is contained inside the log files, identifying the coherency and concurrency is necessary to generate "specificity of attribution". In this work, we focus on isolating multiple simultaneous browser sessions using network and browser-related metadata on browsers that deploy a separate process for each browser session, which we term process-separated browser implementation. In a previous work, it was shown that network artifacts can be associated with browser artifacts to relate network stream with browser sessions on multi-threaded browser implementations. However, in process-separated browser implementations, where each session has its own network stream, the ability to track all network streams via a single process is not available. Therefore, there is a need to associate each network stream with its corresponding process for reconstruction. In this paper, we propose an algorithm to reconstruct multiple simultaneous browser sessions on browser applications that use a separate process for each browser session. We achieve this by developing a representation for the information associated with a browser session. Further, we define two relationships, viz., 'stream coherency' and 'session concurrency' based on the associations discovered among the network and browser artifacts. Finally, we develop an algorithm called "Samhita" to identify number of simultaneous browser sessions that are deployed and associate them with the respective processes and network streams. We take the reader through specially designed experiments to elicit browser-session intelligence and the process to separate out the tabbed sessions using the timing information present in the browser context and session context. |

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.
