[0002] With the development of door lock technology, most door locks support one-time password unlocking to facilitate visitors or service personnel to temporarily unlock and enter the house without holding a physical key or long-term password.

[0003] At present, the one-time password is generated by a cloud server and then sent to the door lock by the cloud server through a network for local storage, so that the door lock generally needs to support networking to realize this function, and the one-time password unlocking cannot be realized for non-networked locks.

[0016] Optionally, it further comprises: if the current input password input by the user to be authorized is obtained within the validity period, the current input password is verified;

[0017] If the current input password input by the user to be authorized is obtained within the period exceeding the validity period, output a password invalidation prompt.

[0018] Optionally, the current one-time password is calculated by the server according to the current seed information by using a preset algorithm.

[0019] The verification of the current input password comprises:

[0020] The reference one-time password is calculated according to the current seed information by using the preset algorithm.

[0022] The method further comprises:

[0023] If the current input password verification is failed, output a password error prompt.

[0024] In a second aspect, the disclosure further provides a one-time password unlocking device, comprising:

[0025] A first output module is configured to output a current seed information to the user to be authorized in response to the triggering operation of the user to be authorized for one-time password unlocking, so that the user to be authorized sends the current seed information to the server through the door lock user terminal, and the server generates a current one-time password accordingly, wherein the current seed information is a seed information that has not been used in previous one-time password unlocking processes, and different seed information corresponds to different one-time passwords generated.

[0026] An unlocking module is configured to execute an unlocking action if the current input password verification is passed, wherein the current input password is input by the user to be authorized according to the current one-time password.

[0052] Figure 1 A flowchart of a one-time password unlocking method provided by an embodiment of the present disclosure.

[0053] In some embodiments of the present disclosure, Figure 1 The method shown can be applied to a door lock, such as a smart door lock, but is not limited thereto.

[0054] As Figure 1 The one-time password unlocking method can include the following steps.

[0055] S110, in response to the trigger operation of the to-be-authorized user for the one-time password unlocking, outputting current seed information to the to-be-authorized user, so that the to-be-authorized user end sends the current seed information to the server through the door lock user end, and the server generates a current one-time password accordingly, wherein the current seed information is seed information that has not been used in the previous one-time password unlocking process, and the one-time password generated by different seed information is different.

[0056] In an embodiment of the present disclosure, in the scenario where the to-be-authorized user wants to perform one-time password unlocking, the to-be-authorized user can input a trigger operation for one-time password unlocking to the door lock, and the door lock can output current seed information to the to-be-authorized user in response to the trigger operation. Then, the to-be-authorized user can use the authorized user end to send the current seed information to the door lock user end, and then the door lock user can use the door lock user end to send the current seed information to the server, and then the server can generate a one-time password according to the current seed information. Wherein, the to-be-authorized user end is a mobile terminal used by the to-be-authorized user, the door lock user end is a mobile terminal used by the door lock user, and the server can include a cloud server, a server cluster, etc., but is not limited thereto.

[0057] Specifically, the trigger operation can be any operation capable of triggering the door lock to enter the one-time unlocking mode. Illustratively, the trigger operation includes inputting a preset number string to the door lock, touching a preset key on the door lock, and / or inputting a voice instruction (such as "I want to unlock once") to the door lock, but is not limited thereto.

[0058] Specifically, the current seed information is seed information used to generate the current one-time password.

[0059] The door lock can output the current seed information to the to-be-authorized user in any possible manner, and the present disclosure does not limit the same. Illustratively, the current seed information is output by display or voice broadcast, but is not limited thereto. It should be noted that for one seed information, if its history has been output by the door lock to the to-be-authorized user, it has been used, otherwise it can be considered as not used.

[0060] Specifically, the current one-time password is a one-time password used in the current one-time password unlocking process.

[0061] It can be understood that since the one-time password corresponding to different seed information is different, and the current seed information has not been used in the previous one-time password unlocking process, the current one-time password generated according to the current seed information has not been used in the previous one-time password unlocking process, so that the uniqueness and unpredictability of the current one-time password can be improved, which is beneficial to enhance the security of the door lock.

[0062] It can also be understood that by setting the current seed information to be sent from the to-be-authorized user end to the door lock user end, and then forwarded to the server by the door lock user end to generate the current one-time password, the current one-time password is generated with the consent of the door lock user, so that the security of the door lock can be further enhanced.

[0063] S120, if the current input password is verified, an unlocking action is performed, wherein the current input password is input by the to-be-authorized user according to the current one-time password.

[0064] Specifically, the current input password is a password input by the to-be-authorized user to the door lock in the current unlocking process.

[0065] In some embodiments of the present disclosure, the current one-time password is sent to the user terminal to be authorized by the server. Specifically, the door lock user terminal can send the communication information (such as the mobile phone number, the account information of the door lock APP, etc.) of the authorized client to the server, so that the server can send the current one-time password to the user terminal to be authorized after generating the current one-time password according to the current seed information. Then, the user to be authorized can input the current input password into the door lock according to the current one-time password, and the door lock verifies the current one-time password. If the verification is passed, the door lock action is executed. In this way, the user terminal to be authorized can receive the current one-time password as soon as possible, and the unlocking speed is improved.

[0066] In some embodiments of the present disclosure, the current one-time password is sent to the user terminal to be authorized by the server. Specifically, the door lock user terminal can send the communication information (such as the mobile phone number, the account information of the door lock APP, etc.) of the authorized client to the server, so that the server can send the current one-time password to the user terminal to be authorized after generating the current one-time password according to the current seed information. Then, the user to be authorized can input the current input password into the door lock according to the current one-time password, and the door lock verifies the current one-time password. If the verification is passed, the door lock action is executed. In this way, the user terminal to be authorized can receive the current one-time password as soon as possible, and the unlocking speed is improved.

[0067] In some embodiments, the door lock can obtain a reference one-time password corresponding to the current seed information. If the current input password and the reference one-time password, the verification is passed, otherwise the verification is not passed.

[0068] In some embodiments, the door lock can obtain a reference one-time password corresponding to the current seed information. If the current input password and the reference one-time password, the verification is passed, otherwise the verification is not passed.

[0069] In some embodiments of the present disclosure, even if the door lock is a non-networked lock, one-time password unlocking can be realized, and it can be ensured that the one-time password used each time the one-time password unlocking is performed is different, thereby enhancing the security of the door lock.

[0070] In another embodiment of the present disclosure, the current seed information is output to the user to be authorized, including:

[0071] S1111, generating random information.

[0072] Specifically, the random information is information randomly generated by the door lock.

[0073] Optionally, the type of the random information includes a random number, a random two-dimensional code, and / or a random picture, but is not limited thereto.

[0074] In some embodiments, the random information includes a random number, and accordingly, S1111 includes: generating the random number.

[0075] Specifically, the random number refers to a value selected according to a certain probability distribution within a certain range, and the selection of these values should be unpredictable.

[0076] In other embodiments, the random information includes a random two-dimensional code, and accordingly, S1111 includes: generating the random two-dimensional code.

[0077] Specifically, the content (encoded information) of the random two-dimensional code is not fixed, but a two-dimensional code that can be different each time it is generated.

[0078] In yet other embodiments, the random information includes a random picture, and accordingly, S1111 includes: generating the random picture.

[0079] Specifically, the random picture is not fixed, but a picture that can be different each time it is generated, wherein the size, resolution, theme or style, etc. of the random picture can be random.

[0080] In yet other embodiments, S1111 includes: randomly selecting one from a plurality of candidate types as a target type; and generating random information of the target type.

[0081] Specifically, the candidate types can include a random number, a random two-dimensional code, and / or a random picture, etc., but are not limited thereto.

[0082] It can be understood that by setting two random stages when generating random information, one is randomly selecting a type, and the other is randomly generating random information of the selected target type, the randomness and unpredictability of the finally generated random information can be enhanced, and thus the security of the door lock can be enhanced.

[0083] S1112, if the state of the random information is valid, the random information is taken as the current seed information, and is output to the user to be authorized, wherein the state being valid is used to represent that the random information has not been used in the previous one-time password unlocking process.

[0084] Specifically, the state of the random information has two types, one is valid, which is used to represent that the random information has not been used in the previous one-time password unlocking process, and the other is invalid, which is used to represent that the random information has been used in the previous one-time password unlocking process.

[0085] In the embodiments of the present disclosure, for one random information, the door lock can switch the state of the random information to invalid after outputting the random information to the authorized user, or switch the state of the random information to invalid after the one-time password generated according to the random information exceeds the validity period, or switch the state of the random information to invalid after the one-time password generated according to the random information passes the verification and performs the unlocking action.

[0086] It can be understood that, by setting the current seed information as the random information, the corresponding generated current one-time password has randomness and unpredictability, so that the security of the door lock can be enhanced.

[0087] In another implementation of the present disclosure, outputting the current seed information to the authorized user includes: S1121, randomly selecting one candidate seed information from a pre-constructed database as the current seed information, and outputting the current seed information to the authorized user.

[0088] S1122, deleting the current seed information from the database.

[0089] Specifically, the type of the candidate seed information can include a random number, a random two-dimensional code, and / or a random picture, but is not limited thereto.

[0090] Specifically, the database includes a plurality of pre-generated candidate seed information.

[0091] It can be understood that, by randomly selecting the current seed information from the database, the randomness and unpredictability of the current seed information can be enhanced, so that the security of the door lock can be enhanced. Moreover, since the current seed information is pre-generated, it can be obtained by random selection in the database, so that the efficiency of obtaining the current seed information is high, and thus the speed of unlocking the one-time password can be improved.

[0092] In another implementation of the present disclosure, the method further includes: if the current input password input by the authorized user is obtained within the validity period, verifying the current input password.

[0093] If the current input password input by the authorized user is obtained in a period exceeding the validity period, a password invalidation prompt is output.

[0094] Specifically, the validity period is a period in which the current one-time password is valid. For example, the start time of the validity period is the time when the current seed information is output to the authorized user, and the end time of the validity period is the time after the start time is delayed by a preset time length, but is not limited thereto.

[0095] In some embodiments, the current one-time password is calculated by the server according to the current seed information by using a preset algorithm, and correspondingly, the checking of the current input password comprises: calculating a reference one-time password according to the current seed information by using the preset algorithm;

[0096] If the current input password is consistent with the reference one-time password, it is determined that the current input password passes the check, otherwise it is determined that the current input password fails the check.

[0097] Specifically, the preset algorithm can include HOTP algorithm, TOTP algorithm, etc., but is not limited thereto.

[0098] Specifically, the specific timing of the door lock "calculating a reference one-time password according to the current seed information by using a preset algorithm" has multiple options. In some examples, the reference one-time password is calculated according to the current seed information by using the preset algorithm after the current seed information is output to the authorized user. In other examples, the reference one-time password is calculated according to the current seed information by using the preset algorithm after the current input password input by the authorized user is received. However, it is not limited thereto.

[0099] It can be understood that by setting the server and the door lock to calculate the current one-time password and the reference one-time password according to the current seed information by using the same preset algorithm, and then checking the current input password against the reference one-time password, the checking method of the current input password is simple and fast, which is conducive to improving the speed of one-time password unlocking.

[0100] In some embodiments, the current one-time password is generated by the server according to the current seed information by using a second pre-trained neural network model, and correspondingly, the checking of the current input password comprises: inputting the current seed information into the second pre-trained neural network model and obtaining a reference one-time password output therefrom;

[0101] If the current input password is consistent with the reference one-time password, it is determined that the current input password passes the check, otherwise it is determined that the current input password fails the check.

[0102] Specifically, the password invalidation prompt is used to remind the authorized user that the one-time password input by him / her has been invalidated.

[0103] The door lock can output the password invalidation prompt to the authorized user in any possible way, and the present disclosure does not limit this. For example, the password invalidation prompt can be output by display or voice broadcast, but it is not limited thereto.

[0104] It can be understood that by setting an expiration date for the current one-time password, the risk of repeated use or deciphering of the current one-time password can be reduced, thereby enhancing the security of the door lock.

[0105] Optionally, the method further comprises: outputting a password error prompt if the current input password fails the verification.

[0106] Specifically, the password error prompt is used to remind the to-be-authorized user that the current input password input by the to-be-authorized user is incorrect.

[0107] The door lock can output the password error prompt to the to-be-authorized user in any possible manner, which is not limited in the present disclosure. For example, the password error prompt can be output by display or voice broadcast, but is not limited thereto.

[0108] It can be understood that the to-be-authorized user can input an incorrect password during inputting the current one-time password to the door lock. By outputting the password error prompt when the current input password fails the verification, the user can be reminded to input the correct current one-time password in time to avoid exceeding the validity period of the current one-time password.

[0138] a to-be-authorized user terminal 102 configured to send current seed information to a door lock user terminal;

[0139] a door lock user terminal 103 configured to send the current seed information to a server;

[0140] a server 104 configured to generate a current one-time password according to the current seed information.

[0141] Figure 5 A one-time password unlocking process of a one-time password unlocking system provided by the embodiment of the present disclosure is shown in FIG. 1. Figure 5 As shown, a to-be-authorized user operates a local door lock (for example, inputs a specific number or presses a specific button) and makes the door lock enter a specific mode. The door lock locally generates a random number A (i.e., current seed information) and displays it to the to-be-authorized user in the form of broadcasting or keyboard display. The to-be-authorized user informs the door lock user of the random number A through other channels. The door lock user inputs the random number A on the door lock user terminal, and the door lock user terminal reports the random number A to the cloud (i.e., the server). The cloud generates a one-time password B (i.e., the current one-time password) through an algorithm C according to the random number A, and sends the one-time password B to the door lock user terminal. The door lock user informs the to-be-authorized user of the one-time password B through other channels. The to-be-authorized user inputs the one-time password B on the door lock, and the door lock checks the legality of the one-time password B through the algorithm C consistent with the cloud. If the check is passed, the door is unlocked. After the door is successfully unlocked, the random number A is invalidated on the door lock, and the door cannot be opened through the same one-time password B. In order to ensure security, the door lock has a timing function. The random number A generated by the door lock is valid within a certain period of time (for example, within 10 minutes). If the correct one-time password B is input within the valid period, the door is unlocked. If the valid period is exceeded, the random number A is invalidated on the door lock.

[0142] The above description is only a specific embodiment of the present disclosure, which enables those skilled in the art to understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure will not be limited to these embodiments described herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

Claims

1. A method for unlocking a lock using a one-time password, characterized in that, Applied to door locks, including: In response to the trigger operation of the user to unlock the door with a one-time password, the current seed information is output to the user to enable the user to send the current seed information to the server through the door lock user terminal, thereby enabling the server to generate the current one-time password. The current seed information is seed information that has not been used in previous one-time password unlocking processes, and different seed information corresponds to different one-time passwords. If the currently entered password passes verification, the unlocking action is executed, wherein the currently entered password is input by the user to be authorized based on the current one-time password; the step of outputting the current seed information to the user to be authorized includes: Generate random information. If the state of the random information is valid, then use the random information as the current seed information and output it to the user to be authorized. The state of being valid is used to indicate that the random information has not been used in any one-time password unlocking process. Alternatively, a candidate seed information can be randomly selected from a pre-built database as the current seed information, and output to the user to be authorized, and the current seed information can be deleted from the database.

2. The method according to claim 1, characterized in that, The types of random information include random numbers, random QR codes, and / or random images.

3. The method according to claim 1, characterized in that, The current one-time password is sent by the server to the client to be authorized, or by the server through the door lock client to the client to be authorized.

4. The method according to claim 1, characterized in that, Also includes: If the currently entered password is obtained from the user to be authorized within the validity period, then the currently entered password is verified. If the currently entered password from the user to be authorized is obtained within the time period exceeding the validity period, a password expiration message will be output.

5. The method according to claim 4, characterized in that, The current one-time password is calculated by the server using a preset algorithm based on the current seed information; The verification of the currently entered password includes: Using the preset algorithm, a reference one-time password is calculated based on the current seed information; If the currently entered password matches the reference one-time password, then the current entered password verification is determined to be successful; otherwise, the current entered password verification is determined to be unsuccessful. The method further includes: If the current input password fails to be verified, a password error message will be output.

6. A device for unlocking a lock using a one-time combination lock, characterized in that, include: The first output module is used to respond to the trigger operation of the user to unlock the door with a one-time password, and output the current seed information to the user to enable the user to send the current seed information to the server through the door lock user terminal, so that the server generates the current one-time password accordingly. The current seed information is seed information that has not been used in previous one-time password unlocking processes, and different seed information corresponds to different one-time passwords. The unlocking module is used to perform an unlocking action if the currently entered password passes the verification, wherein the currently entered password is entered by the user to be authorized based on the current one-time password; The first output module is specifically used to generate random information. If the status of the random information is valid, the random information is used as the current seed information and output to the user to be authorized. The status of being valid is used to indicate that the random information has not been used in any one-time password unlocking process. Alternatively, a candidate seed information is randomly selected from a pre-built database as the current seed information and output to the user to be authorized. The current seed information is then deleted from the database.

7. A computer-readable storage medium, characterized in that, The storage medium stores a computer program that, when executed by a processor, causes the processor to implement a method for unlocking the lock using a one-time password as described in any one of claims 1-5.

8. A door lock, characterized in that, include: processor; Memory, used to store executable instructions; The processor is configured to read the executable instructions from the memory and execute the executable instructions to implement the one-time password unlocking method according to any one of claims 1-5.

9. A one-time password unlocking system, characterized in that, include: The door lock as described in claim 8; The user terminal to be authorized is used to send the current seed information to the door lock user terminal; The door lock user terminal is used to send the current seed information to the server; The server is used to generate a current one-time password based on the current seed information.
