Digital Witness: Remote Method for Volunteering Digital Evidence on Mobile Devices

摘要

Law enforcement requires methods of digital evidence collection from victim or witness devices in a minimally invasive manner. Victims and witnesses are often concerned with minimizing the exposure of data on their phone to authorities. In this paper we describe a system for the secure submission of digital evidence and a micro-service for creating and monitoring chain of custody. These tools minimize device data exposure, encourage cooperation from victims and witnesses, and enforce accountability with regards to handling digital evidence.
