Abstract: In an embodiment, a server receives—a digital key request for a digital key to unlock a smart lock. A biometric feature request for collecting a biometric feature from the mobile device is generated and sent to the mobile device. A biometric feature corresponding to the biometric feature request is received. Identity information and a device identifier of the smart lock is received from another server. Based on the identity information, a matching biometric feature stored in a biometric feature database is determined. An identity of a user corresponding to the received biometric feature is verified based on the matching biometric feature. After the identity of the user is verified, smart lock information is identified. A digital key for unlocking the smart lock is generated based on the digital key request and the smart lock information and sent to the mobile device.
