H. (data subject) – Court Ruling (Germany, 2026)

The data subject had his personal data restricted in the population register due to risks to life and safety based on his work.

The transmitted data consisted only of the data subject’s last name, which was not sensitive and did not increase the risk to his safety, despite the register restriction. End-to-end encryption was therefore not required. Third, the court held that no obligat
