Security and Intelligence are moving from an analogue to a digital world. Evidence in complex criminal cases now comprises mainly of digital data, most of which is in the form of text, documents, images, video-, and audio recording, and associated metadata. The volume of data per case is also growing exponentially. In the Netherlands, the police and tax authorities together handle an estimated 10.000 cases a year each of which – on average – 4 terabytes of data, a million files and 10 million traces. The volume and heterogeneity of the data impacts all aspects of the security process. The DSRC works in close collaboration with the Co van Ledden Hulsebosch centre for forensic science to develop methods for handling such large amounts of data and helping investigators to find evidence in such collections.
