New projects

The group decided to develop a simple glossary of forensic terms.

The group had a long discussion about Deepfakes and the importance of either making a statement or showing people how to distinguish current signs of synthesized voice. Decision was to invite 2 guests to the groups regular meeting next month to clarify certain aspects of Deepfakes so that we can draft a Position Paper.

The group discussed updating two standards:
