This paper explores the critical role of non-content data (NCD), provided by electronic communications service providers in aiding criminal investigations. As highlighted by the Law Enforcement Agencies (LEAs) and the European Commission, NCD plays a fundamental role in identifying suspects and discerning behavioral patterns. Despite its significance, LEAs encounter various challenges in effectively analyzing the extensive volume of NCD. To address this issue, this paper presents the importance of (although simulated but realistic) data collection, the technologies that can be built, and the methods for detecting the suspect within the framework of the TRACY project. These techniques aim to enhance capabilities of LEAs by processing large-scale NCD and aligning it with existing evidence. By prioritizing the tracing of suspects’ movements and integrating data from diverse NCD sources, TRACY’s initial approach on synthetic data promises to significantly advance the identification of offenders involved in serious and organized crime.
