Hardly a fair comparison. However the few identical twins I know have been very mindful of how their individual behavior affects the other.

Of course I realised the comparison would be somewhat controversial, it was actually the point of bringing it up. However, if you have the time I would appreciate it if you tried to articulate why you think the comparison is unfair, instead of just a general dismissal.

Your (twin’s) photo is unlikely to be used for:

* Identifying future medical risk factors

* Solving 30-year-old cold cases where DNA is the only evidence

* Identifying parentage in adoption cases

But my (twin's) photos could likely be used used for:

* Linking them to the location of a crime using Clearview AI and similar scraping facial recognition services

* Creating fake but believable defamatory photos and videos, such as deepfakes

* Being scraped and used in fake profiles by spambots and other nefarious actors

* Being exploited as a tool in identify theft and identify fraud, via various kinds of social engineering.

Do you not consider some of these scenarios worthy of a similar amount of consideration?

I consider them to be unavoidable, barring some extreme off-the-grid efforts. Your photo is out there. Your DNA doesn’t have to be.

I'd argue not, since a single photography contains much, much less information than a full DNA fingerprint.

Not for identifying or incriminating you it doesn't given the practical risk of how the information can be used.

That's a fair point. However, I'm not entirely sure I buy the premise. With the advent of deepfakes and internet scraping facial recognition, I think a public photo collection of your entire likeness could be considered least somewhat at risk for abuse, when compared to the risk that a confidential fingerprint with ~25% of your genes is leaked and then used against you.
