Wear a hood and sunglasses at all times in pubic spaces so that it would be hard to make a good shot of you from three sides. A complex, dynamic hairdo would also be helpful. That is, if you're at risk of being impersonated, e.g. if you possess or control something valuable. Better yet, devise non-obvious verbal protocols that should be followed by you and your counter-party a decision about something important is to be discussed over a video call. Even if that counter-party is your parent or co-founder. Maybe especially then.

Another box of nails into admissibility of video recordings in court, sadly.
