TrustVault on your iPhone serves a crucial role in the process of signing transactions. To ensure that the person initiating the transaction is indeed you, we utilize unique information that is securely stored on your device. This sensitive information resides within the Secure Enclave, a specialized component of your iPhone designed to enhance security.
When you decide to send a transaction, it is imperative for us to verify that the approval is genuinely coming from you. To achieve this, we require you to authenticate your identity through Touch ID or Face ID. This biometric authentication process effectively signs the transaction by leveraging the unique information that has been securely stored in your Secure Enclave. By doing so, we ensure that the transaction is confirmed only when it is initiated by the rightful owner of the device.
The information stored in the Secure Enclave is exclusive to your device, meaning that no other device can access or replicate this data. Additionally, this information is designed to remain within the Secure Enclave itself, making it one of the most secure storage methods available. In fact, it has never been hacked, which speaks volumes about its reliability. By combining the Secure Enclave with biometric authentication methods such as Touch ID and Face ID, we can be confident that the transaction is being signed by you on a device that we trust. This innovative approach allows your iPhone to function as a highly secure "key" for your transactions.
