Metadata minimisation protects privacy by limiting data traces like contacts, locations, and patterns. Using compartmentalisation, VPNs, duress PINs, and open-source OS like GrapheneOS enhances security in hostile digital environments.
Duress PINs provide covert defense during device seizure by triggering panic actions like wipes or lockdowns. Hardened systems (GrapheneOS, AOSP) enhance coercion resistance tailored to threat models.
