step A, inputting and storing user fingerprint information in a memory of the intelligent cloud lock 1;
step B, when a door opener touches the fingerprint collector with a finger, the fingerprint collector collects a fingerprint image of the door opener, the MCU processor 10 reads the fingerprint image of the door opener and edits the fingerprint image into door opener fingerprint information, and meanwhile, the MCU processor 10 sends a verification code request instruction to the safety chip 11;
step C, after receiving the verification code request instruction, the security chip 11 generates a security verification code according to the verification code request instruction, and sends the security verification code and the identity authentication data ID2 of the security chip 11 to the MCU processor 10;
step D, after receiving the security verification code, the MCU processor 10 packages the security verification code, the identity authentication data ID2 of the security chip 11 and the fingerprint information of the door opener to generate an unlocking request instruction, and sends the unlocking request instruction to the cloud server 2;
step E, after the cloud server 2 receives an unlocking request instruction, the cloud server 2 compares whether a security verification code is consistent with the identity authentication data ID2 of the security chip 11, if the security verification code is correct, the cloud server 2 encrypts fingerprint information of the door opener, edits the fingerprint information to generate an unlocking instruction, and sends the unlocking instruction to the intelligent cloud lock 1;
step F, after the intelligent cloud lock 1 receives the unlocking instruction, the unlocking instruction is decrypted by using the security chip 11 to obtain door opener fingerprint information, the door opener fingerprint information is compared with the user fingerprint information, if the comparison result is correct, the voice prompt is successful in verification and the unlocking action is executed, and if the comparison result is wrong, the voice prompt is failed in verification and the unlocking action is not executed.
When someone prepares to open the door, a finger needs to be placed on the fingerprint collector for identification, at this time, the MCU processor 10 reads fingerprint information of the door opener and sends an unlocking request instruction to the security chip 11, so that the security chip 11 generates a security verification code, then the MCU processor 10 transmits the security verification code and the fingerprint information of the door opener to the cloud server 2 through a zigbee module, an RF module or a gateway, etc., the cloud server 2 encrypts the fingerprint information of the door opener after comparing the security verification code to form an unlocking instruction, and sends the unlocking instruction to the intelligent cloud lock 1 through a zigbee module, an RF module or a gateway, etc., the intelligent cloud lock 1 decrypts the unlocking instruction through the security chip 11 to obtain the fingerprint information of the door opener, compares the fingerprint information of the door opener with the fingerprint information of the user, and opens the door if the unlocking instruction is correct, and voice prompt is successful, if the verification is wrong, the door is not opened, and voice prompt is failed;
through the hardware encryption method, on one hand, only one identity authentication data ID2 of the security chip 11 is arranged on each security chip 11 in the intelligent cloud lock 1, when a door opener unlocks fingerprints, the security chip 11 generates a security verification code, when the security verification code is compared with the identity authentication data ID2 of the security chip 11 by the cloud server 2, the cloud server 2 does not perform encryption steps, and an unlocking instruction is not generated, and the intelligent cloud lock 1 cannot receive any data, and can prompt that the verification fails and the door cannot be opened if the data is overtime, so that lawless persons can be prevented from performing network stealing behaviors, and the security verification code is consistent with the identity authentication data ID2 of the security chip 11 only when the intelligent cloud lock 1 registers;
on the other hand, the fingerprint data are encrypted to generate an unlocking instruction, so that the unlocking complexity is increased, the unlocking safety is further improved, when the fingerprint is used as an unlocking password, the simple fingerprint data are easy to crack, and a thief enters a house to steal the fingerprint data, so that the property loss of the user is caused.
To explain further, as shown in fig. 3, the secure chip 11 is provided with user identity authentication information,
in the step C, after the security chip 11 receives the verification code request instruction, generates a security verification code according to the verification code request instruction, and sends the security verification code, the authentication data ID2 of the security chip 11, and the user authentication information to the MCU processor 10;
in the step D, after receiving the security verification code, the authentication data ID2 of the security chip 11 and the user authentication information, the MCU processor 10 packages the security verification code, the authentication data ID2 of the security chip 11, the user authentication information and the fingerprint information of the door opener to generate an unlocking request instruction, and sends the unlocking request instruction to the cloud server 2;
step E, after receiving the unlocking request instruction, the cloud server 2 compares the security verification code with the authentication data ID2 of the security chip 11, and if the security verification code is compared correctly, the cloud server 2 encrypts the fingerprint information of the door opener through the user authentication information, edits the encrypted fingerprint information to generate an unlocking instruction, and sends the unlocking instruction to the intelligent cloud lock 1;
in the step F, the intelligent cloud lock 1 decrypts the unlocking instruction through the user identity authentication information in the security chip 11 to obtain the fingerprint information of the door opener.
User identity authentication information is set and stored in the security chip 11, the user identity authentication information is written in when the security chip 11 leaves a factory, and the user identity authentication information in each security chip 11 is unique and consists of 24 characters; the cloud server 2 encrypts the fingerprint information of the door opener through the user identity authentication information to generate an unlocking instruction, and decrypts the unlocking instruction by using the user identity authentication information as a secret key to obtain the fingerprint information of the door opener again.
To be further explained, as shown in fig. 3, different finger contact with the fingerprint collector generates different fingerprint template information;
in the step A, each user is provided with a plurality of user fingerprint template information, and the user fingerprint template information generated by the relative combination of the plurality of user fingerprint template information is stored in a memory of the intelligent cloud lock 1;
and step B, the door opener contacts the fingerprint collector with fingers, the fingerprint collector collects a fingerprint image of the door opener every time when pressing one finger, then the MCU processor 10 identifies and extracts detailed characteristic points in the fingerprint image of the door opener, and edits the detailed characteristic points into door opener fingerprint template information, and after the door opener separately presses a plurality of fingers, a plurality of door opener fingerprint template information are generated and are relatively combined into door opener fingerprint information.
When someone intends to unlock and open the door by fingerprints, the intelligent cloud lock 1 can analyze and obtain fingerprint template information of one door opener every time one finger is pressed, and a plurality of pieces of fingerprint template information of the door openers are relatively combined to form the fingerprint information of the door openers, namely, the comparison between the fingerprint information of the door openers and the fingerprint information of the users is equivalent to the comparison between the fingerprint template information of the door openers and the fingerprint template information of the users;
when the number of the fingerprint template information in the fingerprint information of the door opener is not equal to the number of the fingerprint template information in the fingerprint information of the user, the door opener selects to perform fingerprint identification, the number of the pressed fingers is not equal, and the identification fails, for example, the fingerprint information of the user contains 3 fingerprint template information, namely, the user presses three different fingers as an unlocking password, at the moment, the door opener repeatedly presses the same finger, only can the same finger serve as 1 piece of fingerprint template information, and only when the door opener has three fingers, 3 pieces of fingerprint template information can be generated, so that the safety of the intelligent cloud lock 1 is improved, the unlocking complexity is increased, and the theft difficulty is improved;
when the fingerprint template information of the door opener is not equal to the fingerprint template information of the user, namely the types of fingers pressed by the door opener are not equal, the identification fails, for example, the user presses a thumb and a middle finger to generate two fingerprint template information, and the door opener presses the thumb and a tail finger to generate two fingerprint template information, at the moment, the fingerprint information of the user formed by relatively combining the two fingerprint template information of the user and the fingerprint information of the door opener formed by relatively combining the two fingerprint template information of the door opener are different, so that the identification fails, the door cannot be opened, the complexity of an unlocking password is further improved, and the unlocking password is further prevented from being stolen.
To be more specific, in the step C, after receiving the verification code request instruction, the secure chip 11 randomly generates a secure verification code through a function, and sends the secure verification code to the MCU processor 10.
The function randomly generates a security verification code, and the cloud server 2 inputs the security verification code into the verification function for verification, so that the unlocking instructions sent by the cloud server 2 every time are different, the unlocking instructions cannot be stolen for unlocking, and the security is improved.
