#Opclave How to implement biometric identification? Option 3: Apple Secure Enclave
Newer generations of Apple devices feature a hardware security component called a "Secure Enclave" that is capable of storing keys or signature data. The Apple Secure Enclave is a subsystem implemented in Apple's system-on-chip that is isolated from the main processor to create an isolated secure enclave for a user's important data. Its primary use case is to preserve user data even if the main processor is compromised. Transactions can be signed directly using Apple Secure Enclave's signature mechanism. These signatures are then verified in the blockchain and smart contracts through the security step of Face-Id or Touch-Id.
