Where is fingerprint data stored on an iOS device?

On an iOS device, fingerprint data is stored in the Secure Enclave, a dedicated security coprocessor that handles sensitive information. This data is encrypted and not accessible to the main operating system, ensuring that biometric information remains secure. User fingerprints are transformed into mathematical representations, and only these encrypted templates are stored, not the actual images of the fingerprints. This design helps protect user privacy and enhances the security of the device.
