In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is an architecture diagram of a block chain system according to an embodiment of the present invention. Referring to fig. 1, the blockchain system includes a plurality of locks, each of which is a node in the blockchain system. The coded lock can be a digital coded lock, a fingerprint lock and the like. The combination locks in the blockchain may include combination locks in a regional area, for example, the combination locks in the blockchain may include all of the combination locks in a building, or the combination locks in the blockchain may include all of the combination locks of a predetermined brand in a predetermined geographic region.
In the application, when a user needs to unlock a coded lock, the user can input an unlocking password into the coded lock, the coded lock can request the coded lock in the block chain system to verify the unlocking password, and after the coded lock in the block chain system passes the verification of the unlocking password, the coded lock can execute unlocking operation.

The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may be combined with each other, and the description of the same or similar contents in different embodiments is not repeated.
Fig. 2 is a schematic flowchart of a method for unlocking a combination lock based on a block chain according to an embodiment of the present invention. Referring to fig. 2, the method may include:
s201, a first coded lock in the block chain system acquires an unlocking code.
Optionally, the first combination lock is any combination lock in the blockchain system.
Optionally, the coded lock shown in the embodiment of the present invention may be a digital coded lock (a coded lock unlocked by using a combination of numbers between 0 and 9), a fingerprint lock (a coded lock unlocked by using a fingerprint), a face recognition lock (a coded lock unlocked by using a face image), or the like.
When the types of the coded locks are different, the types of the unlocking codes are also different. For example, when the combination lock is a digital combination lock, the unlocking combination is a string of numbers. When the coded lock is a fingerprint lock, the unlocking code is a fingerprint. When the coded lock is a face recognition lock, the unlocking code is a face image.
Optionally, a password acquisition device is arranged in the first password lock, and a user can input a password in the first password lock through the password acquisition device. For example, when the first combination lock is a digital combination lock, the combination acquiring device may be a numeric keypad between 0 and 9, and the user may input the digital combination through the numeric keypad. When first trick lock is the fingerprint lock, password collection system can be fingerprint sampler, and the user can pass through fingerprint sampler input fingerprint password. When first trick lock is face identification lock, password collection system can be the camera, and the camera can gather the face image.
S202, the first coded lock sends a verification request to the coded locks in the blockchain system, the verification request comprises unlocking passwords, and the verification request is used for requesting the coded locks in the blockchain system to verify the unlocking passwords.
Optionally, the first combination lock may encapsulate the authentication request into a transaction message, and send the transaction message to the combination lock in the blockchain system.
Optionally, the authentication request may further include an identifier of the first combination lock.
In order to ensure the security of data transmission, before the first coded lock sends the verification request, the unlocking password included in the verification request may be encrypted. For example, the unlocking password may be digitally signed, and the signature information after the data signature may be carried in the verification request. For example, the unlocking password included in the authentication request may be a hash value of the unlocking password.
Optionally, the first trick lock may broadcast an authentication request to the trick locks in the blockchain system. For example, a first trick lock may broadcast an authentication request to other than the first trick lock in the blockchain system.
S203, when the number of the coded locks with correct unlocking passwords is verified to be larger than or equal to a first threshold value in the block chain system, the first coded lock executes unlocking operation.
Initially, the user may set the true password of the first password lock through the client, for example, the client may be a mobile phone, a computer, or other devices.
After the user sets the true password of the first combination lock, the true password of the first combination lock may be stored in the first combination lock. Optionally, in order to ensure the security of storing the true password, the encryption information of the true password may be stored in the first combination lock. For example, a hash value of the true password may be stored in the first combination lock.
Optionally, when the true password is a fingerprint password or a face image password, feature extraction may be performed on the fingerprint password or the face image password to obtain a feature value, and the hash value of the feature value is stored in the first combination lock.
After the user sets the true password of the first combination lock, the first combination lock also sends the true password of the first combination lock to other combination locks in the blockchain system. Optionally, in order to ensure the security of the real password, the first combination lock may encrypt the real password and send encryption information of the real password to the other combination locks. For example, a first trick lock may send a hash value of the true password to other trick locks in the blockchain system.
Optionally, when the true password is a fingerprint password or a face image password, the first combination lock may perform feature extraction on the fingerprint password or the face image password to obtain a feature value, obtain a hash value of the feature value, and send the hash value of the feature value to other combination locks in the block chain.
After the password lock in the blockchain system receives the verification request sent by the first password lock, the password lock in the blockchain system verifies the unlocking password in the verification request. The first combination lock can also verify the unlocking password after receiving the unlocking password input by the user. After the unlocking password verification of each password lock in the blockchain system is completed, verification results can be generated, that is, each password lock generates one verification result, and assuming that the blockchain system comprises N password locks in total, the password locks in the blockchain system can generate N verification results in total. The verification result of the unlocking password of one coded lock is that the coded lock verifies that the unlocking password is correct or that the unlocking password is wrong.
Optionally, a consensus node may be set in the blockchain system, and the consensus node may be any one of the coded locks in the blockchain system. After the verification result is generated by the coded locks in the blockchain system, the verification result is sent to the consensus node, so that the consensus node can generate a consensus result according to the received verification result, and the consensus result is used for indicating that the unlocking code verification of the coded locks in the blockchain system on the first coded lock is successful or the verification fails. The identification of the first combination lock may be included in the consensus result. The consensus node may send the consensus result to all the coded locks in the block chain, and after the first coded lock receives the consensus result, if the consensus result indicates that the unlocking code verification is successful, and the first coded lock determines that the consensus result includes the identifier of the first coded lock, the first coded lock performs the unlocking operation.
For the first coded lock, the unlocking code can be verified through the following feasible implementation modes: the method comprises the steps that a first Hash value of a true password of a first password lock is stored in the first password lock, after the first password lock receives an unlocking password, the first password lock obtains a second Hash value of the unlocking password, the first password lock judges whether the first Hash value and the second Hash value are the same or not, if yes, the verification result is that the unlocking password is correct, and if not, the verification result is that the unlocking password is wrong.
For any one other coded lock except the first coded lock in the blockchain system, the unlocking code can be verified through the following feasible implementation modes: and judging whether a first hash value of the real password of the first password lock is stored locally, and if not, acquiring the first hash value of the real password of the first password lock from other password locks in the block chain system. And acquiring the unlocking password in the verification request, acquiring a second hash value of the unlocking password, judging whether the first hash value and the second hash value are the same, if so, determining that the verification result is that the unlocking password is correct, and if not, determining that the verification result is that the unlocking password is wrong.
Optionally, when the number of the coded locks for verifying that the unlocking password is correct in the blockchain system is greater than or equal to the first threshold, the consensus result indicates that the coded locks in the blockchain system successfully verify the unlocking password; when the number of the coded locks for verifying that the unlocking code is correct in the blockchain system is smaller than a first threshold value, the consensus result indicates that the coded locks in the blockchain system fail to verify the unlocking code.
For example, assuming that the blockchain system includes N cipherlocks, the consensus node can obtain N verification results. If K verification results in the N verification results are correct for verifying the unlocking password, when K is larger than or equal to a first threshold value, the consensus result indicates that the unlocking password is successfully verified, and when K is smaller than the first threshold value, the consensus result indicates that the unlocking password is failed to be verified.
Optionally, the first combination lock includes a mechanical component, and when the number of combination locks for verifying that the unlocking password is correct in the blockchain system is greater than or equal to the first threshold, the first combination lock controls the mechanical component to perform the unlocking operation.
According to the method for unlocking the coded lock based on the block chain, provided by the embodiment of the invention, when a user needs to unlock the first coded lock, the user can input the unlocking password into the first coded lock, the first coded lock sends an authentication request to other coded locks in the block chain system so as to authenticate the unlocking password of the coded lock in the block chain system, and when the number of the coded locks for authenticating the unlocking password in the block chain system is larger than or equal to a first threshold value, the first coded lock can execute unlocking operation. In the process, the coded lock in the block chain system is controlled to be opened according to the unlocking code, and only when a plurality of coded locks in the block chain system are controlled by a hacker, the hacker can control the coded lock to be opened, so that the situation that the centralized remote server controls the coded lock to be opened is avoided, and the unlocking safety of the coded lock is further improved.
On the basis of any one of the above embodiments, the following provides a detailed description of the unlocking method of the fingerprint lock with the embodiment shown in fig. 3.

s301, the first password lock receives a first hash value of the real password sent by the client.
Optionally, after the user sets the true password of the first password lock through the client, the client may obtain the first hash value of the true password and send the first hash value to the first password lock. After the first cryptographic lock receives the first hash value, the first cryptographic lock may store the first hash value. For example, the first combination lock may store the first hash value and the identification of the first combination lock in correspondence.
Optionally, when the true password is a fingerprint password or a face image password, the client may extract a feature value from the fingerprint password or the face image password, and obtain a first hash value of the feature value.
S302, the first coded lock sends coded information to other coded locks in the block chain, wherein the coded information comprises the identification of the first coded lock and the first hash value.

S308, the first coded lock sends the generated verification result to other coded locks in the blockchain system.

S309, the second coded lock acquires a first hash value corresponding to the first coded lock.
Optionally, if the second coded lock joins the blockchain system before the first coded lock sends the password information, the second coded lock locally stores the first hash value corresponding to the first coded lock. If the second coded lock is added into the block chain system after the first coded lock sends the coded information, the second coded lock does not locally store the first hash value corresponding to the first coded lock.
Optionally, if the second coded lock locally stores the first hash value corresponding to the first coded lock, the second coded lock locally obtains the first hash value, and if the second coded lock does not locally store the first hash value corresponding to the first coded lock, the second coded lock obtains the first hash value from other coded locks in the block chain system.

By executing S309-S312, the second combination lock may obtain an authentication result of authenticating the unlocking password, and send the generated authentication result to other combination locks except for the second combination lock in the blockchain system.
It should be noted that, the other combination locks except the first combination lock in the blockchain system execute the steps shown in S309-S312 to obtain the verification result corresponding to the unlocking password.
And S313, the consensus node generates a consensus result according to the received verification result.
Optionally, the common node may be any node in the blockchain system.
Optionally, the consensus result comprises an identification of the first combination lock and a final result of the verification (success or failure).

If the consensus result indicates that the unlocking password authentication fails, the first password lock may not perform any operation.
It should be noted that, after receiving the consensus result, the other coded locks except the first coded lock in the blockchain system determine that the consensus result does not include the identification thereof, and then do not process the consensus result.
After S314, the trick lock in the blockchain system also generates blocks and adds the blocks to the blockchain.
