Much work performed by forensic document examiners is authentication of handwriting. Most of this work is authentication of signatures. Advances in computer software has increased the accuracy of the results. This work often requires skill in matching patterns of writing. The underlying basis for handwriting comparison is learning the different ways a person writes across writing sessions. The forensic document examiner uses tools such as microscopes to examine the writing in question to find small details that a simulator will not discover. The document examiner learns whether the questioned writing fits within the patterns observed in the person's known writing. 

This seminar uses case studies to illustrate methods of authentication. Cases include the Zodiac Killer and the 2018 Zahau v. Shacknai case that resolved whether Rebecca Zahau was murdered or committed suicide at the Spreckels Mansion on Coronado Island.
