The Association of Digital Forensics, Security and Law (ADFSL)


The proper generation and preservation of digital data from Event Data Recorders (EDRs) can provide invaluable evidence to automobile crash reconstruction investigations. However, data collected from the EDR can be difficult to use and authenticate, complicating the presentation of such information as evidence in legal proceedings. Indeed, current techniques for removing and preserving such data do not meet the court’s standards for electronic evidence. Experimentation with an EDR unit from a 2001 GMC Sierra pickup truck highlighted particular issues with repeatability of results. Fortunately, advances in the digital forensics field and memory technology can be applied to EDR analysis in order to provide more complete and usable data. The presented issues should assist in the identification and development of a model for forensically sound collection and investigation techniques for EDRs.
