A collaborative visual analytics of trajectory and transaction data for digital forensics: VAST 2014 Mini-Challenge 2: Award for outstanding visualization and analysis

Advanced digital forensics technologies provide powerful basis in criminal investigation. Due to the complexity and diversity of data as well as the increasing quantity of the data, traditional digital forensics technologies have already can not adapt to the analysis requirements. This paper provides a visualization approach to analyze multiple types of data for digital forensics which provide users three interrelated tools: the RadViz tool, the PMViz tool and the SGGViz tool. Our solution focuses on the correlation analysis of trajectories and transactions, and it plays an important role in the process of analyzing the case in VAST 2014 Mini-challenge 2.
