From the blog post I've recently read; https://thelocalstack.eu/posts/linkedin-identity-verificatio...

1. Request your data. Email [email protected] or [email protected]. Under GDPR, they have 30 days to respond.

2. Request deletion. The verification is done. LinkedIn already has the result. There is no reason for Persona to keep your passport scan and facial geometry on their servers. Ask them to delete it.

3. Contact their DPO. [email protected] — that’s their Data Protection Officer. If you want to object to them using your documents as AI training data under “legitimate interests,” this is where you do it.

4. Think twice before verifying. That blue badge might not be worth what you’re trading for it. A checkmark is cosmetic. Biometric data is forever.
