When that trail contradicts sworn testimony, it becomes evidence.<\/p>\n<p>Q2: What information does an electronic signature reveal?<br \/>\nA2: An electronic signature can reveal where and when the document was signed, from which email address, and at what level of validation.

If a document presented as an electronic signature has no envelope number and no IP record, those are the warning signs that the signature may have been cut and pasted in image-editing software.<\/p>\n<p>Q4: Why is electronic-signature forensics a narrow specialty?<br \/>\nA4: This work sits at the intersection of handwriting analysis, forensic document examination, and electronic-signature forensics.
