Published by the National Institute of Justice (NIJ), this report discusses two NIJ funded projects which introduce new methods and tools for collecting and processing digital evidence in cases involving child sexual abuse materials and large-scale computer networks. The NIJ provided funding to Purdue University and the University of Rhode Island. Purdue University created the File Toolkit for Selective Analysis Reconstruction (FileTSAR) for large-scale computer networks which enables on-the-scene acquisition of probative data. FileTSAR then allows detailed forensic investigation to occur either on site or in a digital forensic laboratory environment, with the goal of ensuring admissible digital evidence. The University of Rhode Island developed DeepPatrol, a software tool using machine intelligence and deep learning algorithms to assist law enforcement agencies in investigating child sexual abuse materials.
