Myth of the Day

All digital images must be electronically authenticated to be admissible.
Category: All DME Myths
A digital image, as well as a film photograph, can be authenticated through testimony or other evidence that the image is a fair and accurate representation of what it purports to depict; electronic authentication is not required. Image integrity must not be confused with the requirement to authenticate evidence as a precondition for admissibility in court. Courtroom authentication of an image substantiates that the image is a fair and accurate representation of what it purports to be, whereas integrity verification is the process of confirming that the image presented is complete and unaltered since the time of acquisition. The integrity of digital images can be verified through a number of means, some of which are not electronic.
