[0002] With the progress of science and technology and the improvement of safety concept, intelligent locks begin to enter thousands of families.

[0027] Embodiment one

[0028] Figure 1 A flow chart of a security locking method according to the first embodiment of the present application is provided, the present embodiment can be applicable to the adaptive matching of locking time for different types of error passwords, the method can be executed by a security locking device, the security locking device can be realized in the form of hardware and / or software, and the security locking device can be configured in an electronic device with data processing capability. As shown in the figure, the method comprises: Figure 1

[0029] S110, if it is determined that the input password is an error password, determining the error type of the error password.

[0030] ​The error type can be used to represent the unlocking mode of the smart lock, and can specifically include a standard digital password, a fingerprint, or a card, etc. The smart lock can be a door lock with at least one of the unlocking capabilities of a fingerprint, a standard digital password, and / or a card, etc.

[0031] In this embodiment, if it is determined that the input password is an error password, the error type of the error password needs to be determined first. Optionally, the error type of the error password is determined as follows: if it is determined that the error password is a biometric password or a near field communication signal password, the error type of the error password is determined as a first error type. The first error type can be an error type of an error password that is a biometric password or a near field communication signal (NFC, Near Field Communication) password. The biometric password can include, but is not limited to, a fingerprint, a finger vein, a face, an iris, a palm print, or a voice, etc. The near field communication signal password can be a password set through a near field communication signal, such as an entity identification password, e.g., a card, etc.

[0032] In this embodiment, optionally, the error type of the error password is determined as follows: if it is determined that the error password is a standard digital password, the error password is compared with a preset password in at least one password library; the password library includes a dictionary attack password library, a white list password library, and a history password library; and the error type of the error password is determined according to a comparison result.

[0033] The password library can be a database for storing passwords that is preset. Specifically, the password library can include a dictionary attack password library, a white list password library, and a history password library. The dictionary attack password library can store common, frequently used, and easily cracked passwords (i.e., weak passwords), such as standard digital passwords defined by using continuous, sequential, reverse, or continuous repetition, etc. The dictionary attack password library can be loaded in the smart lock password library when the smart lock is manufactured, or can be updated later through a network and user self-definition. The white list password library can store the standard digital password that the user currently normally enters. The history password library can store the standard digital password that the user has used before. The preset password can be a standard digital password preset in the password library.

[0034] In this embodiment, if it is determined that the incorrect password is a standard numerical password, the incorrect password can be compared with the preset password in the at least one password library (the password library for password cracking, the white list password library and / or the historical password library). For example, the similarity comparison method can be used to compare the incorrect password with the preset password in the at least one password library. Then, the error type of the incorrect password is determined according to the comparison result. The comparison result can include a comparison success and a comparison failure. It should be noted that the similarity comparison method is not limited in this embodiment and can be set according to actual needs. For example, the Euclidean distance, Manhattan distance, cosine similarity or Pearson correlation coefficient method can be used for similarity comparison.

[0035] In this embodiment, the error type of the incorrect password is determined according to the comparison result. For example, if it is determined that the incorrect password is the same as the target password for password cracking in the password library for password cracking, the error type of the incorrect password is determined as the second error type.

[0036] The target password for password cracking can refer to the password for password cracking stored in the password library for password cracking. The second error type can refer to the error type of the incorrect password that is the same as the target password for password cracking. In this embodiment, if it is determined through comparison that the incorrect password is the same as the target password for password cracking in the password library for password cracking, the error type of the incorrect password can be determined as the second error type. It should be noted that when the error type of the incorrect password is the second error type, it indicates that there is a high risk that someone tries to crack the password of the smart lock by using the password for password cracking in the password library for password cracking.

[0037] In this embodiment, the error type of the incorrect password is determined according to the comparison result. For example, if it is determined that the similarity between the incorrect password and the target white list password in the white list password library is greater than or equal to the preset first similarity threshold, the error type of the incorrect password is determined as the third error type.

[0038] The target white list password can refer to the white list password stored in the white list password library. The preset first similarity threshold can refer to the preset similarity threshold related to the white list password, which can be set according to actual needs and is not limited in this embodiment. The third error type can refer to the error type of the incorrect password with a similarity greater than or equal to the preset first similarity threshold to the target white list password.

[0039] In this embodiment, the similarity comparison method can be used to calculate the similarity between the incorrect password and the target white list password in the white list password library. If it is determined that the similarity between the incorrect password and the target white list password in the white list password library is greater than or equal to the preset first similarity threshold, the error type of the incorrect password can be determined as the third error type. It should be noted that when the error type of the incorrect password is the third error type, it indicates that the user is likely to have made a mistake.

[0040] In the embodiment, optionally, the error type of the error password is determined according to the comparison result, including: if it is determined that the similarity between the error password and the target historical password in the historical password library is greater than or equal to a preset second similarity threshold, the error type of the error password is determined as a fourth error type.

[0041] The target historical password can be a historical password stored in the historical password library. The preset second similarity threshold can be a pre-set similarity threshold related to the historical password, which can be set according to actual needs, and the embodiment does not make any limitation. The fourth error type can be the error type of the error password with a similarity greater than or equal to the preset second similarity threshold to the target historical password.

[0042] In the embodiment, the similarity between the error password and the target historical password in the historical password library can be calculated by similarity comparison. If it is determined that the similarity between the error password and the target historical password in the historical password library is greater than or equal to a preset second similarity threshold, the error type of the error password can be determined as a fourth error type. It should be noted that when the error type of the error password is the fourth error type, it indicates that the user is likely to have forgotten the password or the password is inputted unintentionally.

[0043] The present scheme can determine the error type of the error password according to the comparison result between the error password and the preset password in at least one password library when the error password is a standard digital password, so as to distinguish different error password scenarios, so as to match the appropriate smart lock locking time according to different error password scenarios.

[0044] S120, determining an influence factor of the locking time according to the error types of the continuous preset number of error passwords and the weighting factors of the error types.

[0045] The preset number can be a pre-set number of continuous error passwords, which can be set according to actual needs, and the embodiment does not make any limitation. For example, the preset number can be set to 5. The weighting factor can be a pre-set weight value corresponding to each error type, which can be set according to actual needs, and the embodiment does not make any limitation. The weighting factor is greater than or equal to 0, and generally less than or equal to 1, and can also be set to be greater than 1 according to actual conditions. The influence factor can be used to represent the influence degree on the locking time. It can be understood that the greater the influence factor, the greater the influence degree on the locking time; on the contrary, the smaller the influence factor, the smaller the influence degree on the locking time.

[0046] In the embodiment, optionally, the weighting factor of the second error type is greater than the weighting factor of the first error type, the weighting factor of the first error type is greater than the weighting factor of the fourth error type, and the weighting factor of the fourth error type is greater than the weighting factor of the third error type. The product of the weighting factor of the second error type and the preset number is greater than 1, the product of the weighting factor of the first error type and the preset number is greater than or equal to 1, the product of the weighting factor of the fourth error type and the preset number is less than 1, and the product of the weighting factor of the third error type and the preset number is less than 1. For example, the weighting factor of the second error type can be set to 0.5, the weighting factor of the first error type can be set to 0.3, the weighting factor of the fourth error type can be set to 0.1, and the weighting factor of the third error type can be set to 0.05.

[0047] In the embodiment, after determining the error type of the error password, the influence factor of the lock time can be further determined according to the error types of the continuous preset number of error passwords and the weighting factors of the error types. Specifically, the product of the weighting factor of each error type and the input number is first calculated, then the products corresponding to each error type are summed, and the influence factor of the lock time is determined according to the sum result. The sum of the input numbers of each error type is equal to the preset number. For example, it is assumed that the preset number is n, the input number and the weighting factor of the first error type are n1 and a1 respectively, the input number and the weighting factor of the second error type are n2 and a2 respectively, the input number and the weighting factor of the third error type are n3 and a3 respectively, and the input number and the weighting factor of the fourth error type are n4 and a4 respectively. Wherein, n1+n2+n3+n4=n, and a2>a1>a4>a3. The influence factor of the lock time can be determined as A=n1×a1+n2×a2+n3×a3+n4×a4. Wherein, A represents the influence factor of the lock time.

[0048] In the embodiment, after determining the error type of the error password, the influence factor of the lock time can be further determined according to the error types of the continuous preset number of error passwords and the weighting factors of the error types. Specifically, the product of the weighting factor of each error type and the input number is first calculated, then the products corresponding to each error type are summed, and the influence factor of the lock time is determined according to the sum result. The sum of the input numbers of each error type is equal to the preset number. For example, it is assumed that the preset number is n, the input number and the weighting factor of the first error type are n1 and a1 respectively, the input number and the weighting factor of the second error type are n2 and a2 respectively, the input number and the weighting factor of the third error type are n3 and a3 respectively, and the input number and the weighting factor of the fourth error type are n4 and a4 respectively. Wherein, n1+n2+n3+n4=n, and a2>a1>a4>a3. The influence factor of the lock time can be determined as A=n1×a1+n2×a2+n3×a3+n4×a4. Wherein, A represents the influence factor of the lock time.

[0049] The standard lock time can be a pre-set reference lock time, which can be set according to actual needs, and the embodiment does not make any limitation on this. For example, the standard lock time can be set to 300 seconds. The target lock time can be the actual lock time, which can be determined according to the influence factor of the lock time and the preset standard lock time.

[0050] In the embodiment, after the influence factor of the lock time is determined, the target lock time can be determined according to the influence factor of the lock time and the preset standard lock time, so as to subsequently perform the safe locking according to the target lock time. For example, the target lock time can be determined as the product of the influence factor of the lock time and the preset standard lock time, that is, T=A*t. Wherein, T represents the target lock time, and t represents the preset standard lock time.

[0051] Through the above steps, if the error type of the error password is the first error type or the second error type, it is likely that the attacker actively attacks the dictionary, at this time, the influence factor of the lock time is relatively large, and then the target lock time is greater than the preset standard lock time, thereby improving the difficulty of the attacker to crack the dictionary attack, and effectively avoiding the risk of malicious trial and error unlocking; if the error type of the error password is the third error type or the fourth error type, it is likely that the user misinputs, unconsciously misinputs or forgets the password, at this time, the influence factor of the lock time is relatively small, and then the target lock time is less than the preset standard lock time, which can give the user a certain thinking time, and effectively solve the problem that the user needs to wait for a long time due to misinput, thereby improving the user experience while avoiding the risk of malicious trial and error unlocking.

[0052] The technical scheme of the embodiment of the application, if it is determined that the input password is an error password, the error type of the error password is determined; the influence factor of the lock time is determined according to the error types of the continuous preset number of error passwords and the weighted factors of each error type; the target lock time is determined according to the influence factor of the lock time and the preset standard lock time, so as to perform the safe locking according to the target lock time. The technical scheme can improve the security and user experience of the intelligent lock while avoiding the risk of malicious trial and error unlocking.

[0054] Figure 2 A flowchart of a safe locking method provided by the embodiment two of the application is based on the optimization of the above-mentioned embodiment. As shown in the figure, the method of the embodiment specifically includes the following steps: Figure 2

[0055] S210, it is judged whether the input password is illegal input, if yes, S2100 is executed, otherwise S220 is executed.

[0056] ​In this embodiment, when the input password is detected, it is first determined whether the input password is illegal input. For example, when the length of the input numerical password is less than the minimum length required by the smart lock, or the fingerprint, card, etc. exceeds the recognition range of the smart lock password, it can be considered as illegal input, at this time the unlocking function of the smart lock cannot be triggered, therefore it can be selected not to respond, or it can be selected to issue a prompt information (such as voice prompt), which can be set according to actual needs.

[0057] In S220, if it is determined that the input password is an error password, the error type of the error password is determined.

[0058] In S230, if it is determined that the error password is a biometric password or a near field communication signal password, the error type of the error password is determined as a first error type.

[0059] In S240, if it is determined that the error password is a standard numerical password, the error password is compared with a preset password in at least one password library; wherein the password library includes a dictionary attack password library, a white list password library and a history password library.

[0060] In S250, if it is determined that the error password is the same as a target dictionary attack password in the dictionary attack password library, the error type of the error password is determined as a second error type.

[0061] In S260, if it is determined that the similarity between the error password and a target white list password in the white list password library is greater than or equal to a preset first similarity threshold, the error type of the error password is determined as a third error type.

[0062] In S270, if it is determined that the similarity between the error password and a target history password in the history password library is greater than or equal to a preset second similarity threshold, the error type of the error password is determined as a fourth error type.

[0063] The weighting factor of the second error type is greater than the weighting factor of the first error type, the weighting factor of the first error type is greater than the weighting factor of the fourth error type, and the weighting factor of the fourth error type is greater than the weighting factor of the third error type; and the product of the weighting factor of the second error type and a preset number is greater than 1, the product of the weighting factor of the first error type and the preset number is greater than or equal to 1, the product of the weighting factor of the fourth error type and the preset number is less than 1, and the product of the weighting factor of the third error type and the preset number is less than 1.

[0064] In S280, the influence factor of the lock time is determined according to the error types of the continuous preset number of error passwords and the weighting factors of the error types.

[0065] S290, determining a target lock time according to the influence factor of the lock time and a preset standard lock time, to perform the security lock according to the target lock time.

[0066] The specific implementation of S220-S290 can refer to the detailed description in Embodiment One, which will not be repeated here.

[0067] S2100, not responding or sending a reminder message.

[0068] The technical scheme of the embodiment of the application can determine the influence factor of the lock time based on the error type of the wrong password when determining that the input password is not an illegal input, and then determine the target lock time according to the influence factor of the lock time and the preset standard lock time, which can avoid the risk of malicious trial and error to open the lock while further improving the security and user experience of the smart lock.

More specific examples of a machine-readable storage medium will include one or more lines of a program of instructions in a transitory signal, a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.

[0098] To provide for interaction with a user, the systems and techniques described here can be implemented on an electronic device having a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to the user and a keyboard and a pointing device (e.g., a mouse or a trackball) by which the user can provide input to the electronic device. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user can be received in any form, including acoustic, speech, or tactile input.

[0099] The systems and techniques described here can be implemented in a computing system that includes a back end component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front end component (e.g., a user computer having a graphical user interface or a Web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such back end, middleware, or front end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include a local area network (LAN), a wide area network (WAN), a blockchain network, and the Internet.

[0100] The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also known as a cloud computing server or cloud host, which is a host product in the cloud computing service system, to solve the defects of large management difficulty and weak business scalability in traditional physical host and VPS service.

[0101] It should be understood that the various forms of flow shown above can be used to reorder, add or delete steps. For example, each step described in the present application can be executed in parallel, sequentially or in a different order, as long as the desired results of the technical solutions of the present application can be achieved, which is not limited herein.

[0102] The above detailed description does not constitute a limitation on the protection scope of the present application. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
