A Visual Analytics System for CDR and IPDR Based Cybercrime Investigation and Analysis

To track communication trends and suspects related to cybercrimes, Call Detail Records (CDR) and Internet Protocol Detail Records (IPDR) are the very core of an investigation. This paper presents a Visual Analytics System that has been designed to improve the interactive analysis of data during investigations of cybercrime. Upload CDR and IPDR as CSV files, visualize data using interactive maps and heatmaps, and generate profiling dashboards for a given phone number: those are the features the system offers users. Advanced visualizations in the graph form will show how entities are connected, while IMEI-based filtering will track one particular device that can be used across multiple numbers. Profile query and annotation tools for investigative insights could go beyond these. In the future, it is hoped that one will be able to build it with automatic data extraction from all sorts of CDR/IPDR format variations, dynamic toggle graphs and maps, and generate reports in PDF format. This will further extend usability. Such a combination grants this system a holistic platform for law enforcement and forensic operatives to make standard analyses of complex communication data.
