Example Embodiment
[0127] Embodiment 1: Restricted conditions: the user enters valid password A, fingerprint information B and random dynamic code C; valid password A pre-stored in the verification unit 1 、Fingerprint database of visitors allowed to enter the house by the householder, random dynamic code C obtained by the householder's terminal 1 ;
[0128] ①If A=A 1 , when the fingerprint information B is compared with the fingerprint information database of visitors allowed to enter the house by the householder, the corresponding fingerprint information B is found in the information database 1 , B=B 1 ; the authentication is successful, the verification unit prompts "YES", and the fingerprint lock is turned on.
[0129] ②If A≠A 1 , when the fingerprint information B is compared with the fingerprint information database of visitors allowed to enter the house by the householder, the corresponding fingerprint information B is not found in the information database 1 ; the authentication fails...
Example Embodiment
[0132] Embodiment 2: Condition: Continue to operate under the conditions of ②, ③, ④ in Example 1;
[0133]1. After the user verification fails, re-authenticate, and the second verification succeeds, and the fingerprint lock is turned on;
[0134] 2. After the user verification fails, re-authenticate the user. If the user has verified more than 5 times within 5 minutes, and all verification fails, the owner will be alerted.
Example Embodiment
[0135] Embodiment 3: Condition: Continue to operate on the basis of Case 2 of Embodiment 2;
[0136] 1. After the user verification fails, the identity verification is not continued, and the residence time before the fingerprint lock is 15 minutes, and the head terminal has no obvious response;
[0137] 2. After the user verification fails, the identity verification is not continued, and the stay time before the fingerprint lock is 25 minutes, the owner terminal will issue an alarm, and the owner will be alerted.
[0138] 3. After the user verification fails, the identity verification is not continued, and the fingerprint lock is violently dismantled. The head of the household will issue an alarm, and the head of the household will be alerted.
