Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of an implementation environment provided by an embodiment of the present application. Referring to fig. 1, the method for restricting the use of functions provided by the present application may be implemented by a terminal, an authorization information storage device, and a server together.

The terminal can have a communication function, can access the Internet or a local area network, and can be a mobile phone, a tablet computer, intelligent wearable equipment, a desktop computer, a notebook computer and the like.

The authorization information store may be an embedded device having a memory and a processor, and may be connected to the terminal via the internet or a local area network. The device may be a separate device for implementing the storage of the authorization information, or may implement the function of storing the authorization information on other existing devices, for example, the device may be a video storage device, and a technician may allocate a storage space in a memory of the video storage device for storing the authorization information.

The server may be a background server of the target application program, and the server may establish communication with the terminal through the internet. The server may be a single server or a server group, if the server is a single server, the server may be responsible for part of the processing in the method flow of limiting function usage authorization provided by the present application, and if the server is a server group, different servers in the server group may be respectively responsible for different processing in the following schemes, and specific processing allocation situations may be set arbitrarily by a technician according to actual needs, which is not described herein.

Fig. 2 is a flowchart of a method for restricting usage authorization of a function, which is provided in an embodiment of the present application, and is applied to a terminal, referring to fig. 2, and the embodiment includes:

step 201, in the case that a trigger instruction of the target limiting function is detected, a query request is sent to the authorization information storage device.

The authorization information storage device is used for storing authorization information, and the authorization information comprises at least one limit function usable times. The target restriction function may be an application program, and the authorization information of the application program may be acquired each time the application program is used. The target limiting function may be any function in one application program, for example, may be a coding function in a video application program, and when the coding function is used each time, authorization information corresponding to the coding function may be obtained. The authorization information may be stored in the authorization information storage device, but the center soft authorization service (i.e., the authorization service provided in the server) may send the authorization information to the authorization information storage device, or the center soft authorization service may send the authorization information to the terminal first, and then the terminal sends the authorization information to the authorization information storage device, or a technician may directly store the corresponding authorization information to the authorization information storage device according to the upper limit of the usage number of the limiting function.

In this embodiment provided by the present application, taking the target limiting function as an example of any one function in a target application program, the scheme is described in detail, for example, the target limiting function may be a coding function in a video application program, and other thresholds are similar and will not be described again.

Step 202, under the condition that the authorization information sent by the authorization information storage device is received, determining the usable times of the target limiting function based on the authorization information sent by the authorization information storage device, if the usable times of the target limiting function are greater than 0, executing the target limiting function, and sending authorization information updating data to the authorization information storage device.

Fig. 3 is a flowchart of a method for restricting usage of a function according to an embodiment of the present application, which is applied to an authorization information storage device, and referring to fig. 3, the embodiment includes:

step 301, under the condition of receiving a query request sent by a terminal, sending stored authorization information to the terminal, wherein the authorization information comprises at least one usable frequency of limiting functions;

step 302, under the condition that the authorization information updating data sent by the terminal is received, updating the stored authorization information based on the authorization information updating data.

Fig. 4 is a flowchart of a method for restricting usage of functions in an embodiment of the present application, which is applied to interaction between a terminal and an authorization information storage device, and referring to fig. 4, the embodiment includes:

step 401, the terminal obtains an activation code of the target limiting function, sends the activation code of the target limiting function to the server, and receives an upper limit of the use times of the target limiting function sent by the server.

In implementations, the activation code may be an activation code of a target application program purchased in advance by the user. The user can input the activation code into the target application program when using the target application program for the first time or when using the limiting function in the target application program for the first time, and the terminal can send the activation code input by the user to the server for verification. The server stores the corresponding relation between the activation code and at least one limit function use frequency upper limit in the target application program. After the activation code passes the verification of the server, the server may send at least one upper limit of the number of times of limiting function use in the target application corresponding to the activation code to the terminal. After receiving the upper limit of the usage frequency of at least one restriction function in the target application program sent by the server, the terminal can store the upper limit of the usage frequency of at least one restriction function in the target application program. The terminal can encrypt and store at least one upper limit of the limit function use times in the target application program, and does not provide a modification interface for the upper limit of the limit function use times in the target application program for a user in the target application program, and the upper limit of the limit function use times in the target application program can be modified only through the server, so that the upper limit of the limit function use times in the target application program stored in the terminal can not be tampered at will, and the safety of the target application program is improved.

In addition, after the activation code passes the verification of the server, the server may further transmit at least one of the authorization code corresponding to the activation code and the upper limit of the number of times of limiting function use in the target application to the terminal. The authorization code may or may not be identical to the activation code. If not, each activation code can correspond to a unique authorization code, and the corresponding relation between each activation code and each authorization code can be stored in the server. After the terminal receives the authorization code sent by the server and the upper limit of the use times of the limiting functions in the target application program, the authorization code and the upper limit of the use times of the limiting functions in the target application program can be correspondingly stored.

It should be noted that, the activation code is used to verify whether the user has the usage right of the restriction function in the target application program, and if the restriction function in the target application program does not set the usage right, or if the user has been verified by other means that the user has the usage right of the restriction function in the target application program, the program identifier of the target application program, the restriction function identifier of the target restriction function, and other means may be sent to the server to obtain the upper limit of the number of times of usage of the target restriction function.

Step 402, the terminal determines authorization information based on the upper limit of the usage times of the target limiting function.

The usable number of times of the target limiting function included in the authorization information is equal to the upper limit of the usable number of times of the target limiting function.

In an implementation, after receiving the authorization code sent by the server and the upper limit of the usage times of at least one restriction function in the target application program, the terminal may determine the available times of at least one restriction function in the target application program according to the upper limit of the usage times of at least one restriction function in the target application program. Since the user has not used any restriction function in the target application before, the usable number of at least one restriction function in the target application is equal to the corresponding upper limit of the number of uses. The number of times at least one restriction function in the target application can be used and the corresponding restriction function identification can then be formed into authorization information for the target application. The authorization information may include at least one limit in the target application to the number of times the function may be used.

Step 403, the terminal sends the authorization information to the authorization information storage device.

The authorization information storage device may be an embedded device, which opens up space for storing authorization information, which must be cleared by professional means. For example, it may be a network video recorder NVR or a network hard disk recorder DVR.

In practice, the terminal, after having obtained the authorization information, may send the authorization information to the authorization information store. Since the authorization information storage device may store a plurality of pieces of authorization information, for example, authorization information corresponding to target application programs installed by different terminals, the authorization information may also include authorization codes received by the terminals, or in the case that the server does not send authorization codes to the terminals, the terminals may use the activation codes as authorization codes in the authorization information sent to the authorization information storage device, so that the authorization information storage device can distinguish and search the authorization information. Or the terminal can send the authorization information and the authorization code to the authorization information storage device, and the authorization information storage device can correspondingly store the received authorization information and the received authorization code so as to enable the authorization information storage device to distinguish and search the authorization information. In addition, the authorization information may further include an upper limit of the number of times of use of at least one restriction function in the target application, and then it may be determined whether the upper limit of the number of times of use of the restriction function stored locally in the authorization information storage device is adjusted by comparing the upper limit of the number of times of use of the restriction function with the upper limit of the number of times of use of the restriction function stored locally in the terminal.

It should be noted that the steps 401-403 are one possible way for the authorization information storage device to obtain the authorization information corresponding to the target application. The authorization information store may also obtain authorization information in other ways. For example, the server may directly transmit the corresponding authorization information to the corresponding authorization information storage device according to the activation code transmitted by the terminal. If the terminal or the authorization information storage device cannot access the internet, the technician may also store the authorization information to the authorization information storage device before the user uses the target application, or the restricted function of the target application.

Optionally, the upper limit of the number of times of use of the target limiting function may be adjusted, and the corresponding processing is as follows: receiving the upper limit of the use times of the target limiting function after adjustment, which is sent by the server; and replacing the upper limit of the use times of the target limiting function stored locally with the upper limit of the use times of the target limiting function after adjustment.

In implementation, if the number of times the target restriction function is available is exhausted, or in the process of using the target application program, the user wants to increase the number of times the target restriction function is available, the number of times the target restriction function is available may be increased by purchasing the number of times the target restriction function corresponding to the target restriction function is available. For example, the user sets the number of purchases by clicking a purchase option of the upper limit of the number of uses of the target restriction function in the target application, and after the payment is completed, the server may transmit the upper limit of the number of uses of the target restriction function after adjustment to the terminal, and the upper limit of the number of uses of the target restriction function after adjustment may be the number of purchases by the user plus the upper limit of the number of uses of the target restriction function before adjustment. After receiving the adjusted upper limit of the usage frequency of the target limiting function, the terminal can replace the locally stored upper limit of the usage frequency of the target limiting function with the adjusted upper limit of the usage frequency of the target limiting function, and the adjustment of the upper limit of the usage frequency of the target limiting function is completed. The local may further store an adjustment state of at least one restriction function in the target application program, and after the upper limit of the number of times of use of the target restriction function is adjusted, the adjustment state corresponding to the target restriction function may be modified to be adjusted. Therefore, the user can be more flexible in using each limiting function, and the upper limit of the using times of the limiting function can be increased according to the own requirement, so that the usable times of the limiting function can be increased.

Step 404, the terminal sends a query request to the authorization information storage device when detecting the trigger instruction of the target limiting function.

The authorization information storage device is used for storing authorization information, and the authorization information comprises at least one limit function usable times.

In practice, when a user needs to use any restriction function in the target application, then the restriction function may be a target restriction function. The user can generate a trigger instruction corresponding to the target limiting function by clicking a trigger control corresponding to the target limiting function, and after the target application program detects the trigger instruction of the target limiting function, the user can send a query request of the authorization information to the authorization information storage device, wherein the query request can carry an authorization code used by the current target application program so as to acquire the authorization information corresponding to the target application program; in addition, the query request can also carry a limit function identifier of the target limit function; alternatively, the query request may be used to request authorization information for all restricted functions currently stored by the authorization information store.

Optionally, before sending the query request of the authorization information to the authorization information storage device, the terminal may detect whether the upper limit of the usage number of the locally stored target limiting function is adjusted, and then determine to send different query requests according to the detection result, where the corresponding processing is as follows: if the upper limit of the use times of the target limiting function stored locally is detected to be adjusted after the target limiting function is executed last time, sending a query request carrying an adjustment identifier to the authorization information storage device; if the upper limit of the use times of the target limiting function stored locally is not detected to be adjusted after the target limiting function is executed last time, a query request which does not carry an adjustment mark is sent to the authorization information storage device.

In an implementation, the terminal sends a query request of the authorization information to the authorization information storage device in order to determine whether the number of times the target restriction function included in the authorization information is usable is greater than 0, so as to determine whether the user uses the target restriction function. If the server does not update the upper limit of the number of times of use of the locally stored target restriction function, the number of times of use of the target restriction function included in the authorization information is not updated, so the terminal only needs to acquire the authorization information of the number of times of use of the target restriction function included. So if the terminal detects that the upper limit of the number of times of use of the locally stored target restriction function is adjusted after the last execution of the target restriction function, for example, the adjustment state of the locally stored target restriction function is adjusted, a query request carrying an adjustment identification may be sent to the authorization information storage device. To acquire the usable number and the upper limit of the usable number of the target restriction function stored in the authorization information storage device, and to adjust the usable number and the upper limit of the usable number of the target restriction function stored in the authorization information storage device. After the usable number and the upper limit of the number of uses of the target restriction function stored in the authorization information storage device are adjusted, the adjustment state of the locally stored target restriction function may be set to be unadjusted. If the terminal does not detect that the upper limit of the number of times of use of the locally stored target restriction function is adjusted after the last time of executing the target restriction function, a query request without carrying an adjustment identifier can be sent to the authorization information storage device. The method comprises the steps of acquiring the usable times of the target limiting function stored in the authorization information storage device, and determining the usable times of the target limiting function stored in the weight information storage device as the current usable times of the target limiting function. In this way, in the case where the upper limit of the number of times of use of the locally stored target restriction function is not adjusted, the amount of data transmitted between the terminal and the authorization information storage device can be reduced.

Step 405, the authorization information storage device sends the stored authorization information to the terminal when receiving the inquiry request sent by the terminal.

In implementation, after receiving the query request sent by the terminal, the authorization information storage device may query whether the authorization information storage device stores corresponding authorization information according to the authorization code carried in the query request, and if the authorization information corresponding to the authorization code is queried, the corresponding authorization information may be sent to the terminal. The authorization information may include the usable times of each limiting function in the target application program, or the usable times and the upper limit of the usable times. If the query request carries the function identifier of the target limiting function, the authorization information only including the usable times of the target limiting function or the usable times and the upper limit of the usable times can be sent to the terminal. When the inquiry request is for requesting the authorization information of all the limit functions currently stored in the authorization information storage device, the authorization information storage device may transmit the stored authorization information of all the limit functions to the terminal after receiving the inquiry request transmitted from the terminal, and specifically, may transmit the stored authorization information of all the limit functions of the usable number or usable number and upper limit of the usable number to the terminal.

Optionally, the authorization information storage device further sends different authorization information corresponding to the different query requests in step 404, and the corresponding processing is as follows: under the condition that a query request which is sent by a terminal and does not carry an adjustment mark is received, sending authorization information comprising the usable times of a target limiting function to the terminal; and under the condition of receiving a query request carrying an adjustment identifier sent by the terminal, sending authorization information comprising the upper limit of the using times and the usable times of the target limiting function to the terminal.

In an implementation, if the authorization information storage device receives a query request that is sent by the terminal and does not carry the adjustment identifier, authorization information including the number of times the target restriction function can be used may be sent to the terminal. If the authorization information storage device receives a query request carrying an adjustment identifier sent by the terminal, authorization information including an upper limit of the number of times of use and the number of times of usable times of the target restriction function can be sent to the terminal.

Step 406, the terminal determines the usable times of the target limiting function based on the authorization information sent by the authorization information storage device when receiving the authorization information sent by the authorization information storage device, and if the usable times of the target limiting function are greater than 0, the terminal executes the target limiting function.

In an implementation, after receiving the authorization information sent by the authorization information storage device, the terminal may determine the number of times the target restriction function is available according to the authorization information sent by the authorization information storage device.

Wherein if the number of times of availability of at least one restriction function in the target application included in the authorization information, the number of times of availability of the target restriction function included in the authorization information may be determined according to the function identification of the target restriction function, and the number of times of availability of the target restriction function included in the authorization information may be determined as the current number of times of availability of the target restriction function, if the current number of times of availability of the target restriction function is greater than 0, the target restriction function may be executed, if the current number of times of availability of the target restriction function is equal to 0, the target restriction function may not be executed, and the number of times that the target restriction function has not been used may be prompted to the user, or the like.

The terminal may not receive the authorization information sent by the authorization information storage device, where the terminal may fail to obtain the authorization information due to a network or hardware failure, or the corresponding authorization information is not stored in the authorization information storage device. If the acquisition of the authorization information fails due to network or hardware faults and the like, a message of the acquisition failure of the authorization information can be displayed in the terminal, and after the corresponding faults are solved, a query request is sent to the authorization information storage device again. If the corresponding authorization information is not stored in the authorization information storage device, the authorization information storage device may send a message to the terminal that the corresponding authorization information is not stored. The terminal may display that the current authorization information storage device does not store the corresponding authorization information if it receives the message sent by the authorization information storage device that the corresponding authorization information is not stored. Or, it may also be that the authorization information storage device sends the authorization information of all the restriction functions currently stored to the terminal according to the query request sent by the terminal, and the terminal does not query the received authorization information for the authorization information with the authorization code consistent with the target restriction function, so that the terminal determines that the corresponding authorization information is not stored in the authorization information storage device.

Optionally, under the condition that the authorization information sent by the authorization information storage device is not received, determining the authorization information based on the upper limit of the use times of the target limiting function stored locally, wherein the usable times of the target limiting function included in the authorization information are equal to the upper limit of the use times of the target limiting function stored locally, and sending the authorization information to the authorization information storage device.

In the implementation, the situation that the corresponding authorization information is not stored in the authorization information storage device may be that the terminal does not generate corresponding authorization information to be sent to the terminal after receiving the upper limit of the usage frequency of at least one limiting function of the target application program sent by the server, so that if the terminal receives the message sent by the authorization information storage device and not storing the corresponding authorization information, the terminal may also generate corresponding authorization information according to the upper limit of the usage frequency of each limiting function of the target application program stored this time to send the corresponding authorization information to the authorization information storage device, and then the terminal may send a query request to the authorization information storage device again to obtain the corresponding authorization information.

In one implementation possibility, since the upper limit of the usage number of the locally stored target restriction function may be adjusted, after receiving the authorization information sent by the authorization information storage device, the upper limit of the usage number of the target restriction function included in the authorization information may be compared with the upper limit of the usage number of the locally stored target restriction function, and it is determined whether the locally stored target restriction function is adjusted. If the upper limit of the number of uses of the target restriction function stored locally is identical to the upper limit of the number of uses of the target restriction function included in the authorization information transmitted from the authorization information storage device, the number of uses of the target restriction function included in the authorization information transmitted from the authorization information storage device is determined as the number of uses of the target restriction function, in which case the current number of uses of the target restriction function may be decremented by 1 to obtain the updated number of uses of the target restriction function as authorization information update data, or the upper limit of the number of uses of the target restriction function and the updated number of uses of the target restriction function may be used as authorization information update data, or an update instruction carrying an adjustment value of the number of uses may be used as authorization information update data; if the upper limit of the number of uses of the locally stored target restriction function is inconsistent with the upper limit of the number of uses included in the authorization information transmitted by the authorization information storage device, the number of uses of the target restriction function is determined based on the upper limit of the number of uses of the locally stored target restriction function and the authorization information transmitted by the authorization information storage device, in which case the authorization information update data may be determined based on the upper limit of the number of uses of the locally stored target restriction function and the determined number of uses of the target restriction function minus 1, or an update instruction carrying the number of uses adjustment value and the upper limit adjustment value may also be used as the authorization information update data.

In the implementation, if the terminal does not detect whether the target limiting function is adjusted, after receiving the authorization information sent by the authorization information storage device, the terminal may compare the upper limit of the usage number of the target limiting function included in the authorization information with the upper limit of the usage number of the target limiting function stored locally, and if the comparison result is consistent, it is indicated that the upper limit of the usage number of the target limiting function stored locally is not adjusted, and may determine the number of times the target limiting function included in the authorization information is available as the current number of times the target limiting function is available. If the comparison results are inconsistent, the upper limit of the using times of the target limiting function stored locally is adjusted, the usable times and the upper limit of the using times of the target limiting function in the authorization information are required to be adjusted, and then the current usable times of the target limiting function are determined according to the usable times and the upper limit of the using times of the target limiting function in the authorization information after adjustment.

Optionally, the process of determining the current number of times the target restriction function is available according to the number of times the target restriction function is available and the upper limit of the number of times the target restriction function is available in the authorization information after adjustment may be as follows: and determining that the usable times of the target limiting function is the sum of usable times and upper use times limit values in the authorization information sent by the authorization information storage device, wherein the upper use times limit values are the difference between the upper use times limit of the target limiting function stored locally and the upper use times limit of the target limiting function included in the authorization information sent by the authorization information storage device.

Wherein, the current usable times of the target limiting function can be determined by the following formula:

A＝B-C+D

wherein A is the current usable times of the target limiting function, B is the upper limit of the usable times of the target limiting function stored locally, C is the upper limit of the usable times of the target limiting function contained in the authorization information sent by the authorization information storage device, and D is the usable times of the target limiting function contained in the authorization information sent by the authorization information storage device.

In another implementation possibility, in the above step 404, the terminal may detect whether the upper limit of the usage number of the locally stored target restriction function is adjusted, and then send different processing of the query request, so the processing corresponding to the different processing of the query request sent in the above step 404, and the processing of determining the number of usable times corresponding to the target restriction function based on the authorization information sent by the authorization information storage device may be as follows:

if the terminal sends a query request which does not carry an adjustment identifier to the authorization information storage device, determining the usable times of the target limiting function based on the usable times of the target limiting function included in the authorization information sent by the authorization information storage device, wherein in this case, the current usable times of the target limiting function can be reduced by 1 to obtain the usable times of the target limiting function after updating, which are used as authorization information updating data, or an updating instruction carrying an adjustment value of the usable times can be used as authorization information updating data; if a query request carrying an adjustment identifier is sent to the authorization information storage device; the usable number of times of the target restriction function is determined based on the locally stored upper limit of the number of times of use of the target restriction function and the upper limit of the number of times of use of the target restriction function included in the authorization information transmitted from the authorization information storage device, in which case the authorization information update data may be determined based on the locally stored upper limit of the number of times of use of the target restriction function and the determined value of the number of times of use of the target restriction function minus 1, or an update instruction carrying the number of times of use adjustment value and the upper limit of use adjustment value may also be used as the authorization information update data.

In an implementation, if the terminal sends a query request that does not carry the adjustment identifier to the authorization information storage device, and receives the authorization information including the number of times of availability of the target restriction function sent by the authorization information storage device, the number of times of availability of the target restriction function included in the authorization information may be determined as the current number of times of availability of the target restriction function. If the terminal sends a query request carrying an adjustment identifier to the authorization information storage device and receives the authorization information including the upper limit of the number of use times and the number of usable times of the target limiting function sent by the authorization information storage device, the terminal can update the received authorization information. And then determining the current usable times of the target limiting function according to the usable times and the upper limit of the usable times of the target limiting function in the updated authorization information. Wherein, the current usable times of the target limiting function are determined by the following formula:

A＝B-C+D

Step 407, the terminal sends the authorization information update data to the authorization information storage device.

In implementation, if the target limiting function is executable, during execution of the target limiting function, authorization information update data of the authorization information is determined, and then the authorization information update data is sent to the authorization information storage device, so that the authorization information stored in the authorization information storage device is updated, for example, the usable number of times corresponding to the target limiting function in the authorization information is reduced by 1. The authorization information update data may be an update instruction, where the update instruction may carry an authorization code of the target application program and an update value of the usable number of times of the target limiting function, for example, the update value may be 1, and the authorization information storage device may increase the usable number of times of the authorization code to the target limiting function in the corresponding authorization information by the corresponding update value after receiving the update instruction. The authorization information update data may also be updated authorization information and an authorization code of the target application, and the updated authorization information includes the number of times the target restriction function is available after the update. The authorization information storage device may replace the locally stored authorization information corresponding to the authorization code with the updated authorization information after receiving the updated authorization information and the authorization code. For example, the target application is HCP (HikCentral Professional, a video surveillance management software), and the authorization information store is NVR (Network Video Recorder ). As shown in fig. 5, after the user uses the target limiting function, the HCP may acquire corresponding authorization information from the NVR, then update the authorization information according to the service rule, that is, reduce the number of times the target limiting function is available, and then send the updated authorization information to the NVR, and at the same time, may display the result of the HCP executing the target limiting function to the user.

Corresponding to step 406, when the upper limit of the number of times of use of the target restriction function stored in the terminal is adjusted, after determining the current number of times of use of the target restriction function, the authorization information update data may be determined based on the upper limit of the number of times of use of the target restriction function and the value obtained by subtracting 1 from the number of times of use of the target restriction function stored locally.

In implementation, the current available times of the target limiting function can be reduced by 1 after the current available times of the target limiting function are determined, so that the updated available times of the target limiting function are obtained. The authorization information update data may be updated authorization information, where the updated authorization information includes the usable number of times of the target restriction function after updating and the upper limit of the use number of times of the target restriction function stored this time. The authorization information update data may be an update instruction, and the difference between the upper limit of the usage number of the locally stored target restriction function and the upper limit of the usage number of the target restriction function sent by the authorization information storage device may be determined again, and the difference between the usable number of the target restriction function after the update and the usable number of the target restriction function sent by the authorization information storage device is carried into the update instruction as the update values of the upper limit of the usage number of the target restriction function and the usable number of the target restriction function, respectively, so as to instruct the authorization information storage device to update the authorization information stored in the authorization information storage device according to the update values in the update instruction.

Step 408, the authorization information storage device updates the stored authorization information based on the authorization information update data when receiving the authorization information update data sent by the terminal.

In implementation, the authorization information update data may be an update instruction, where the update instruction may carry update values corresponding to the usable times and the limiting functions of the target limiting function, and after receiving the update instruction, the authorization information storage device may adjust the usable times and the upper limits of the usable times and the use times of the target limiting function in the corresponding authorization information to the corresponding update values respectively, so as to obtain the usable times and the upper limits of the usable times of the target limiting function after updating; the update instruction may further carry an authorization code of the target application program, and the authorization information storage device may determine, after receiving the update instruction, a usable number and an upper limit of a usable number of the target restriction function in the authorization information corresponding to the authorization code according to the authorization code. The authorization information update data may also be updated authorization information, and the updated authorization information may include a number of times after the target limit function is updated, or may include an upper limit of the number of times after the target limit function is updated, and the authorization information storage device may replace the locally stored authorization information with the updated authorization information after receiving the updated authorization information and the authorization code; the authorization information storage device may receive the authorization code at the same time as receiving the updated authorization information, and may replace the locally stored authorization information with the updated authorization information according to the authorization code.

According to the embodiment of the application, the obtained usable times of the target limiting function are stored in the authorization information storage device, and when the trigger instruction of the target limiting function is detected, whether the target limiting function can be executed or not is determined by obtaining the usable times of the target limiting function stored in the authorization information storage device. By adopting the method and the device, the storage of the usable times of the target limiting function in the local is avoided, and the possibility that the usable times of the target limiting function are tampered can be reduced.
