Right. EXIF does not include any kind of signature.

Canon's Solomon probably is clueless about EXIF, but his point is somewhat valid. While it's true that a Linux hacker can make the EXIF tags say whatever he wants, there probably is not a widely available, easy to use EXIF editor for Windows, which means the vast majority of pictures taken will make it to court with a valid modification datetime tag.

Though a court can't use the EXIF data as absolute proof in favor of the guy who submitted the photograph, it can use it as absolute proof against him.
