Triaging digital device content at-scene:- Formalising the decision-making process

The prominence of technology usage in society has inevitably led to increasing numbers of digital devices being seized, where digital evidence often features in criminal investigations. Such demand has led to well documented backlogs placing pressure on digital forensic labs, where in an effort to combat this issue, the 'at-scene triage' of devices has been touted as a solution. Yet such triage approaches are not straightforward to implement with multiple technical and procedural issues existing, including determining when it is actually appropriate to triage the contents of a device at-scene. This work remains focused on this point due to the complexities associated with it, and to support first responders a nine-stage triage decision model is offered which is designed to promote consistent and transparent practice when determining if a device should be triaged.
