ARM TrustZone
The ARM security technology that splits the processor at hardware level into a "secure" and a "normal" world to isolate sensitive operations.
// EXPLANATION
Fingerprint templates, cryptographic keys and payment data are handled in the secure world; even if Android in the normal world is compromised it cannot reach them. It underpins many mobile security features.
