| Abstract: | Modern criminal investigations are increasingly challenged by the large volume and diversity of multimodal data, including audio, text, and metadata from intercepted communications. Building upon the Autocrime platform (a multimodal platform for combating organized crime) developed under the ROXANNE project, this report presents TRACY Canvas, a visualization tool developed entirely using open-source technologies to render complex communication networks. TRACY Canvas enables the exploration of diverse network types, including telephone networks, speaker networks from Autocrime outputs, terminal-based networks, and individual level networks with concurrent physical presence. These capabilities support behavioral and topological analysis of suspects within criminal networks. The tool offers features such as temporal filtering, dynamic edge rendering, and metadata overlays, allowing law enforcement agencies to interactively analyze both content and non-content signals. Validated on real and simulated cases, our tool connects backend analytics (i.e., Autocrime platform) with an intuitive front-end (i.e., visualisation tool) to support efficient and transparent criminal investigations. |
