Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below by referring to the accompanying drawings and examples.
Fig. 1 is a schematic frame structure of a service system where an intelligent device in an embodiment is located. Referring to fig. 1, in one embodiment, a service system may include a smart device 10, a device client 20, and an import client 30. The smart device 10 may be an embedded device such as IPC (IP Camera) in the security field, or may be a terminal device such as a mobile terminal.
As can be seen in fig. 1, the smart device 10 is loaded with a device host application 200 and an import application 300. The device main application 200 may be a factory self-contained application of the intelligent device 10, and the intelligent device 10 may also be installed in a factory self-contained device sub-application 210; the import application 300 is an application imported after the smart device 10 leaves the factory. Alternatively, the device main application 200 and the device sub-application 210 may be considered as implant applications of the smart device 10, and the import application 300 may be considered as an import application of the smart device 10.
The device main application 200, the device sub-application 210, and the import application 300 may share the hardware resources 100 of the smart device 10. For example, shared hardware resources 100 may include: a processor 110 for running the device main application 200, the device sub-application 210, and the import application 300; AI (Artificial Intelligence ) chip 120 for providing hardware support for intelligent analysis algorithms (Intelligent Analysis Algorithm); the nonvolatile storage medium 130 may include different kinds of media such as FLASH (FLASH memory) or magnetic disk, and is used to store application packages of the device main application 200, the device sub-application 210, and the import application 300, and may also be used to store data or files required for running the device main application 200, the device sub-application 210, and the import application 300; a volatile storage medium 140, such as DDR (Double Data Rate) memory, for running caches of the device main application 200, the device sub-application 210, and the import application 300; a network card 150 for network interaction of the smart device 10; and a peripheral interface 160 for auxiliary input and output of the smart device 10.
The smart device 10 can maintain normal provision of various device services by running the device main application 200 or simultaneously running the device main application 200 and the device sub-application 210. For example, assuming the smart device 10 is IPC, the device services it provides may include, in particular, video streaming (e.g., YUV video streaming), alerting, video recording, pictures, journaling, networking, time, metadata (metadata) structured information, and so on. It is to be understood that this is merely an illustration of a device service, and the scope of the device service may not be limited thereto.
Wherein the import application 300 may be an application developed or integrated by a third party other than the manufacturer of the smart device 10, in which case the import application 300 may also be referred to as a third party application; alternatively, the importing apparatus 300 may be an application developed or integrated by the manufacturer of the smart apparatus 10, and in this case, the importing apparatus 300 may be considered as an extended application configured by user-definition according to the user's needs.
Whether the import application 300 is a third party application or an extension application, the operation of the import application 300 at the smart device 10 requires an activation license. Further, the activation permission verification of the import application 300 may be implemented based on a License Key (License Key) imported to the smart device 10.
Fig. 2 is a schematic diagram of an authorization permission mechanism for an importing application in the service system shown in fig. 1. Referring to fig. 6, a License 500 may be generated by License server 50 and imported to smart device 10. The license 500 may include a validity period of the license 500, an application name and an application identifier of an import application that the license 500 intends to activate, a device identifier (e.g., a device serial number or a MAC address of an intelligent device) of a license-bearing device of the import application that the license 500 intends to activate, license identification information such as version information, and verification information such as an authorization code (license code) and a signature.
At least one import application 300 may be imported into the smart device 10 at the time of actual use, and for each import application 300, the license 500 intended to activate the import application 300 at the smart device 10 may be imported in the manner shown in fig. 6, and for each import application 300, the import of the license 500 may occur once or more than once.
Thus, in order to facilitate management of a license 500 imported to the smart device 10 in the manner shown in fig. 6, the following embodiments provide a license management method of the smart device for the device host application 200 of the smart device 10.
FIG. 3 is an exemplary flow diagram of a license management method for a smart device in one embodiment. Referring to fig. 3, in this embodiment, the license management method may include:
s310: when a valid license is imported into the smart device, the device host application saves the imported license in the smart device's nonvolatile storage medium and writes the expiration date parsed from the license.
The nonvolatile storage medium in which the license is saved and the expiration date is written in this step may be one of a plurality of media carriers of the nonvolatile storage medium 130 shown in fig. 1. For example, the application packages of the device host application and the import application may be stored in FLASH of the nonvolatile storage medium 130, and this step may be to save the license and the write expiration date in other media carriers such as a disk other than FLASH.
S320: in response to an activation state of a license to which an import application in a smart device is imported, a device host application consumption updates a validity period of the license written in a nonvolatile storage medium.
In this step, the device host application may update the validity period in the consumption record entry of the license written in the nonvolatile storage medium in a decreasing manner according to a preset time step (for example, 1 day).
S330: when the validity period of a license written in a nonvolatile storage medium is updated to be exhausted, a device host application sets a lead-in application activated by the license to a deactivated state.
The inactive (inactive) state of the import application in this step may be regarded as a state opposite to the active (active) state. The activation state of the import application is an operation state determined by the import application, and the deactivation state of the import application in this step may be a management state determined by the device host application. That is, if the import application is not activated at the intelligent device, the import application refuses to start the operation at the intelligent device; if the device host application places the import application in a deactivated state, the device host application masks access requests initiated by the import application.
The above-described flow may be performed once every time a valid license import occurs, whereby, every time a valid license is imported by the smart device, the device host application of the smart device may save the license and its validity in the non-volatile storage medium of the smart device, so that during the period in which each imported application in the smart device is activated by the license, the device host application may consume and update the validity period of the license in the non-volatile storage medium, whereby the smart device can realize unified management of the license validity period of the imported application without resorting to network interaction, and is not limited by the type and number of imported applications and the number of license importations.
In actual use, there may be cases where a license is misimported, for example, an imported application for which the imported license is intended to be activated is not imported at the smart device, or the imported license is not for activation of the imported application at the smart device. Therefore, in order to avoid causing execution of the above-described flow to an invalid license, the license management method in this embodiment may further introduce a validity verification mechanism.
Fig. 4 is an expanded flow diagram of the license management method of fig. 3 incorporating a validity verification mechanism. Referring to fig. 4, the process shown in fig. 3 can be further extended to include the following steps:
S400: in response to a license import operation of the smart device, the device host application validates the imported license to detect whether the license intends to activate the imported application that has been imported into the smart device at the smart device.
Wherein, if it is detected that the license intends to activate the import application that has been imported into the smart device at the smart device, it may be determined that the license is valid, and S410 is performed; otherwise, the license is discarded and the process is ended.
Specifically, the validity verification performed in this step may include: the device main application analyzes the imported license to obtain an application identifier and a device identifier, the device main application matches the analyzed application identifier with the application identifier of the imported application imported in the intelligent device, and matches the analyzed device identifier with the device identifier of the intelligent device; when both the application identification and the device identification match successfully, it is determined that the imported license intends to activate the imported application that has been imported in the smart device at the smart device.
S410: when the validity verification of the imported license is successful, the device host application saves the imported license in a nonvolatile storage medium of the intelligent device and writes a validity period parsed from the license.
S420: in response to an activation state of a license to which an import application in a smart device is imported, a device host application consumption updates a validity period of the license written in a nonvolatile storage medium.
S430: when the validity period of a license written in a nonvolatile storage medium is updated to be exhausted, a device host application sets a lead-in application activated by the license to a deactivated state.
The above-described S410 to S430 can be regarded as substantially the same as S310 to S330 in fig. 3.
In practical use, the activation state of the imported application in the smart device may be continued by re-applying the license, so that the license imported by the smart device may be used to activate the imported application for the first time, and may also be used to continue the activation state of the activated imported application. Wherein the content in the license of each application is not identical for the same import application, and license identification information such as version information may be different.
To this end, a validity period superimposing mechanism may be further introduced to avoid that a validity period that has not been exhausted is consumed by mistake due to the replacement of a license.
Fig. 5 is an expanded flow diagram of the license management method of fig. 4 incorporating a validity period stacking mechanism. Referring to fig. 5, the process shown in fig. 4 can be further extended to include the following steps:
S500: in response to a license import operation of the smart device, the device host application validates the imported license to detect whether the license intends to activate the imported application that has been imported into the smart device at the smart device.
This step may be considered to be substantially the same as S400 in fig. 4, i.e., if it is detected that the license intends to activate the import application that has been imported into the smart device at the smart device, it may be determined that the license is valid, and S510 is performed; otherwise, the license is discarded and the process is ended.
S510: when the validation of the imported license is successful, the device host application detects whether the imported application that the imported license is intended to activate has been currently activated in the smart device.
If the import application is currently active in the smart device, S520 is performed, otherwise S530 is performed.
S520: the device host application queries the nonvolatile storage medium for the license that caused the current activation state of the import application and stops the consumption update for the validity period of the found license, and then proceeds to S530.
S530: the device host application saves the imported license in the nonvolatile storage medium of the smart device and writes the expiration date parsed from the license.
S540: in response to an activation state of a license to which an import application in a smart device is imported, a device host application consumption updates a validity period of the license written in a nonvolatile storage medium.
S550: when the validity period of a license written in a nonvolatile storage medium is updated to be exhausted, a device host application sets a lead-in application activated by the license to a deactivated state.
The above-described S530 to S550 can be regarded as substantially the same as S310 to S330 in fig. 3.
Multiple importation of a license for the same importation application may involve the use of a license whose period of validity has been exhausted by repeated importation, in addition to the case of continuation of the active state, with the intention of spoofing the importation application to re-activate. In order to avoid such fraud, an anti-fraud import mechanism may be further introduced, which on the one hand ensures that licenses whose validity period is not exhausted can be used legally upon re-import, and on the other hand prevents that licenses whose validity period is exhausted from illegally activating the import application upon re-import.
Fig. 6 is an expanded flow diagram of the license management method of fig. 4 incorporating an anti-spoofing importation mechanism. Referring to fig. 6, the process shown in fig. 4 can be further extended to include the following steps:
S600: in response to a license import operation of the smart device, the device host application validates the imported license to detect whether the license intends to activate the imported application that has been imported into the smart device at the smart device.
This step may be considered to be substantially the same as S400 in fig. 4, i.e., if it is detected that the license intends to activate the import application that has been imported into the smart device at the smart device, it may be determined that the license is valid, and S610 is performed; otherwise, the license is discarded and the process is ended.
S610: when the validity verification of the imported license is successful, the device host application detects whether the imported license is already stored in the nonvolatile storage medium.
If it is detected that the imported license has been saved in the nonvolatile storage medium, S620 is performed;
otherwise, S640 is performed.
S620: the device host application queries whether the expiration date for which the license remains in the non-volatile storage medium is exhausted.
If the validity period of the imported license remaining in the nonvolatile storage medium is not exhausted, S630 is performed;
if the validity period of the imported license remaining in the nonvolatile storage medium is exhausted, the device host application determines that the import of the license belongs to import spoofing, discards the imported license, and ends the present flow.
S630: in response to an activation state of a license to which an import application in a smart device is imported, a device host application begins consuming updates with a validity period for which the license remains in a non-volatile storage medium.
S640: the device host application saves the imported license in the nonvolatile storage medium of the smart device and writes the expiration date parsed from the license.
S650: in response to an activation state of a license to which an import application in a smart device is imported, a device host application consumption updates a validity period of the license written in a nonvolatile storage medium.
S660: when the validity period of a license written in a nonvolatile storage medium is updated to be exhausted, a device host application sets a lead-in application activated by the license to a deactivated state.
The above-described S640 to S660 can be regarded as substantially the same as S310 to S330 in fig. 3.
The above-described flow of introducing the validity period superimposing mechanism shown in fig. 5 and the flow of introducing the anti-spoofing introducing mechanism shown in fig. 6 are both extended on the basis of the flow shown in fig. 4. It will be appreciated that this does not mean that the validity period superimposing mechanism and the anti-spoofing importation mechanism necessarily rely on a validity verification mechanism introduced in the flow as shown in figure 4. The processes shown in fig. 5 and 6 are obtained by expanding the process shown in fig. 4, so as to clearly embody the time sequence relation between the validity period superposition mechanism and the anti-fraud import mechanism and the validity verification mechanism, and the validity verification mechanism introduced in the process shown in fig. 4 is considered to be more beneficial to saving the processing resources of the main application of the device.
Also, although the validity period superimposing mechanism and the spoofing prevention introducing mechanism are respectively embodied in the flows shown in fig. 5 and 6, this does not mean that mutual exclusivity exists between the two, that is, the validity period superimposing mechanism introduced in the flow shown in fig. 5 and the spoofing prevention introducing mechanism introduced in the flow shown in fig. 6 may be used in combination.
Fig. 7 is an expanded flow diagram of the license management method shown in fig. 4 incorporating both a validity period superimposing mechanism and an anti-spoofing import mechanism.
S700: in response to a license import operation of the smart device, the device host application validates the imported license to detect whether the license intends to activate the imported application that has been imported into the smart device at the smart device.
This step may be considered to be substantially the same as S400 in fig. 4, i.e., if it is detected that the license intends to activate the import application that has been imported into the smart device at the smart device, it may be determined that the license is valid, and S710 is performed; otherwise, the license is discarded and the process is ended.
S710: when the validity verification of the imported license is successful, the device host application detects whether the imported license is already stored in the nonvolatile storage medium.
If it is detected that the imported license has been saved in the nonvolatile storage medium, S720 is performed;
otherwise, S740 is performed.
S720: the device host application queries whether the expiration date for which the license remains in the non-volatile storage medium is exhausted.
If the validity period of the imported license remaining in the nonvolatile storage medium is not exhausted, S730 is performed;
if the validity period of the imported license remaining in the nonvolatile storage medium is exhausted, the device host application determines that the import of the license belongs to import spoofing, discards the imported license, and ends the present flow.
S730: in response to an activation state of a license to which an import application in a smart device is imported, a device host application begins consuming updates with a validity period for which the license remains in a non-volatile storage medium.
S740: the device host application detects whether the imported license intended to activate the imported application has been currently activated in the smart device.
If the import application is currently active in the smart device, S750 is performed, otherwise S760 is performed.
S750: the device host application queries the nonvolatile storage medium for the license that caused the current activation state of the import application and stops the consumption update for the validity period of the found license, and then proceeds to S760.
S760: the device host application saves the imported license in the nonvolatile storage medium of the smart device and writes the expiration date parsed from the license.
S770: in response to an activation state of a license to which an import application in a smart device is imported, a device host application consumption updates a validity period of the license written in a nonvolatile storage medium.
S780: when the validity period of a license written in a nonvolatile storage medium is updated to be exhausted, a device host application sets a lead-in application activated by the license to a deactivated state.
The above-described S760 to S780 can be regarded as substantially the same as S310 to S330 in fig. 3.
To distinguish between a license that performs an expiration date consumption update and a license that stops an expiration date consumption update, an expiration date consumption record table and an expiration date history record table may be created in a non-volatile storage medium of the smart device, accordingly:
for S310, S530, S640, and S760, the device host application may add a consumption record entry for the imported license in a validity period consumption record table of the nonvolatile storage medium, wherein the consumption record entry includes the license and its validity period, and an application identification of the imported application that the license intends to activate.
For S510 and S740, the device host application may detect whether the imported license intended to activate the imported application has been currently activated in the smart device; if the import application is currently activated in the smart device, for S540 and S750, the device host application queries the expiration record table for the consumption record entry matching the application identifier of the import application, deletes the queried consumption record entry from the expiration record table, and moves the queried consumption record entry to the expiration history table in the nonvolatile storage medium.
For S610 and S710, the device host application may detect whether the imported license is already saved in the validity period consumption record table and the validity period history record table of the nonvolatile storage medium;
when it is detected that the imported license has been saved in the expiration date consumption record table or the expiration date history record table, the device host application inquires whether the expiration date reserved in the expiration date consumption record table or the expiration date history record table is exhausted for S620 and S720;
if the validity period of the imported license is not exhausted, the device host application starts to consume the update with the validity period of the license in the validity period consumption record table in response to the activation state of the license imported by the import application in the smart device for S630 and S730. That is, the license found in the expiration date consumption record table remains its consumption record entry in the expiration date consumption record table and continues the consumption update of the expiration date. For the license found in the expiration history table, the consumption record entry is transferred from the expiration history table to the expiration consumption record table, and then the expiration date consumption update is continued.
In addition, in this embodiment, the license management method of the intelligent device may further introduce an anti-riot import mechanism to defend an illegal user from frequently importing, into the intelligent device, an invalid license acquired through an illegal way for a certain import application.
Fig. 8 is an expanded flow diagram of the license management method of fig. 4 introducing an anti-riot import mechanism. Referring to fig. 8, the process shown in fig. 4 can be further extended to include the following steps:
s800: in response to a license import operation of the smart device, the device host application detects whether an import application for which an imported license is intended to be activated is recorded as a license import prohibited state in the nonvolatile storage medium.
If the imported license is intended to activate the imported application recorded in the non-volatile storage medium as a license import disabled state, the device host application discards the imported license;
if the imported application, for which the imported license is intended to be activated, is not recorded in the nonvolatile storage medium as a license import disabled state, the device host application enables validity verification of the license and performs S810.
S810: the device host application validates the imported license to detect whether the license intends to activate the imported application that has been imported in the smart device at the smart device.
If it is detected that the license intends to activate the import application that has been imported into the smart device at the smart device, it may be determined that the license is valid, and S820 is performed;
otherwise, S850 is performed.
S820: when the validity verification of the imported license is successful, the device host application saves the imported license in a nonvolatile storage medium of the intelligent device and writes a validity period parsed from the license.
S830: in response to an activation state of a license to which an import application in a smart device is imported, a device host application consumption updates a validity period of the license written in a nonvolatile storage medium.
S840: when the validity period of a license written in a nonvolatile storage medium is updated and exhausted, the device main application sets a lead-in application activated by the license to a deactivated state;
s850: when the validity verification of the imported license fails, the device host application records a license import failure time in the non-volatile storage medium of the smart device for the imported application that the license is intended to activate, and discards the imported license.
The above-described S820 to S840 can be regarded as substantially the same as S310 to S330 in fig. 3.
Fig. 9 is a schematic diagram of a state maintenance flow in coordination with the flow shown in fig. 8. Referring to fig. 9, the license management method in this embodiment may further include a state maintenance procedure independent of the procedure shown in fig. 8, specifically including:
s910: the device host application reads the license import failure time recorded for the import application in the non-volatile storage medium of the smart device.
This step may be performed at predetermined time intervals (e.g., every 5 minutes).
S920: and the equipment main application detects whether the license import failure frequency of the import application exceeds a preset threshold value according to the read license import failure time of the import application.
If it is detected that the license import failure frequency of the import application is higher than the preset threshold, S920 is continuously executed, otherwise S910 is returned to wait for the next detection.
S930: the device host application sets the import application to a license import prohibition state and performs timing maintenance on the license import prohibition state of the import application.
For example, the preset threshold used in this step may be set to be once every minute of failure in the lead-in. Further, the timing maintenance performed on the license importation prohibition state of the importation application in this step aims to maintain the license importation prohibition state for a preset duration (for example, 30 minutes).
S940: when the timing of the license import prohibition state for the import application arrives, the device host application releases the license import prohibition state for the import application and returns to S910 to wait for the next detection.
The flow shown in fig. 9 may be a flow that is executed independently in accordance with the time of failure in import of the license recorded in the flow shown in fig. 8. And, the flow shown in fig. 8 may also refer to fig. 5 to 7, and further introduce a validity period superposition mechanism and/or a fraud prevention import mechanism.
Fig. 10 is an exemplary structural diagram of a license management apparatus of the smart device in one embodiment. Referring to fig. 10, in one embodiment, a license management apparatus 1000 may be carried in a device host application of a smart device, and may include:
and a license scheduling module 1010, configured to, when a valid license is imported into the smart device, save the imported license in the nonvolatile storage medium 1030 of the smart device, and write a validity period parsed from the license.
Wherein the non-volatile storage medium 1030 shown in fig. 10 may be one of a variety of media carriers for the non-volatile storage medium 130 shown in fig. 1. For example, the application packages of the device host application and the import application may be stored in FLASH of the nonvolatile storage medium 130, and the nonvolatile storage medium shown in fig. 10 may be other medium carrier such as a disk other than FLASH.
A validity period management module 1020 for consumption updating a validity period of a license written in the nonvolatile storage medium 1030 in response to an activation state of the license to which the import application in the smart device is imported; when the expiration date of a license written in the nonvolatile storage medium is updated to be exhausted, the license scheduling module 1010 is notified to put the import application activated by the license in a deactivated state.
The license scheduling module 1010 may store the imported license and its validity period in a storage space opened to the validity period management module 1020 in the nonvolatile storage medium 1030, and the activation state of the license to which the validity period management module 1020 responds to the imported application is determined according to the notification sent by the imported application to the license scheduling module 1010.
And, the validity period management module 1020 may update the validity period in the consumption record entry of the license written in the nonvolatile storage medium 1030 in a decremental manner according to a preset timing step (for example, 1 day).
In addition, the deactivation (inactive) state set by the license scheduling module 1010 for the import application may be regarded as a state opposite to the activation (active) state. Also, the activation state of the import application is the running state determined by the import application, and the deactivation state set by the license scheduling module 1010 may be regarded as the management state determined by the smart device. That is, if the import application is not activated at the intelligent device, the import application refuses to start the operation at the intelligent device; if the device host application places the import application in a deactivated state, the smart device considers the import application as inactive.
Based on the license management device, each time the intelligent device imports a valid license, the intelligent device can store the license and the valid license in the nonvolatile storage medium thereof, so that the intelligent device can consume and update the valid period of the license in the nonvolatile storage medium during the period that each imported application in the intelligent device is activated by the license, and the intelligent device can realize unified management of the valid period of the license of the imported application without network interaction and is not limited by the type and the number of the imported applications and the imported number of the licenses.
In actual use, there may be cases where a license is misimported, for example, an imported application for which the imported license is intended to be activated is not imported at the smart device, or the imported license is not for activation of the imported application at the smart device. Therefore, in order to avoid causing execution of the above-described flow to an invalid license, the license management apparatus in this embodiment may further introduce a validity verification mechanism.
Accordingly, the license scheduling module 1010 may be further configured to, in response to a license import operation of the smart device, validate the imported license to detect whether the license intends to activate an import application that has been imported in the smart device at the smart device. Wherein if it is detected that the license intends to activate the import application that has been imported into the smart device at the smart device, it may be determined that the license is valid; otherwise, the license is discarded.
For example, the license scheduling module 1010 may parse the imported license to obtain an application identifier and a device identifier, match the parsed application identifier with an application identifier of an imported application imported in the smart device, and match the parsed device identifier with the device identifier of the smart device; when both the application identification and the device identification match successfully, it is determined that the imported license intends to activate the imported application that has been imported in the smart device at the smart device.
In practical use, the license imported by the intelligent device may be used for activating the imported application for the first time, and may also be used for continuing the activated state of the activated imported application, wherein the content in the license applied for each time is not identical for the same imported application, and license identification information such as version information may be different. For this reason, the license management apparatus in this embodiment may further incorporate a validity period superimposing mechanism to avoid that a validity period that has not been exhausted is consumed by mistake due to replacement of a license.
Accordingly, the license scheduling module 1010 may be further configured to save the imported license in the nonvolatile storage medium of the smart device, and detect whether the imported application that the imported license intends to activate is currently activated in the smart device before writing the validity period parsed from the license; if the imported application is currently activated in the intelligent device, querying a non-volatile storage medium for a license which causes the current activation state of the imported application, and canceling the consumption update of the validity period of the searched license by the validity period management module.
Moreover, in order to avoid fraudulent import applications reactivation due to repeated importation of licenses whose expiration dates have been exhausted. In order to avoid such fraud, the license management apparatus in this embodiment may further introduce an anti-fraud import mechanism that, on the one hand, ensures that a license whose validity period is not exhausted can be used legally at the time of re-import, and, on the other hand, prevents the license whose validity period is exhausted from illegally activating the import application at the time of re-import.
Accordingly, the license scheduling module 1010 may be further configured to store the imported license in the nonvolatile storage medium of the smart device, and detect whether the imported license is already stored in the nonvolatile storage medium before writing the validity period parsed from the license; when it is detected that the imported license has been saved in the nonvolatile storage medium, inquiring whether the validity period of the license saved in the nonvolatile storage medium is exhausted; discarding the imported license if the validity period of the imported license remaining in the nonvolatile storage medium is exhausted; if the validity period of the imported license remained in the nonvolatile storage medium is not exhausted, the validity period management module is triggered to restore consumption update with the validity period of the license remained in the nonvolatile storage medium in response to the activation state of the imported license imported by the imported application in the intelligent device.
In order to defend against an illegal user frequently importing an invalid license acquired through an illegal route to a smart device, the license management apparatus in this embodiment may further incorporate an anti-riot import mechanism.
Accordingly, the license scheduling module 1010 may be further configured to detect whether an imported application, which the imported license is intended to activate, is recorded as a license import prohibited state in the nonvolatile storage medium before validity verification of the imported license; if the imported license is intended to activate the imported application recorded in the non-volatile storage medium as a license import disabled state, the device host application discards the imported license; if the imported license is intended to activate the imported application that is not recorded in the non-volatile storage medium as a prohibited license import state, the device host application enables validity verification of the license.
And, the license scheduling module 1010 may be further configured to record, in the non-volatile storage medium of the smart device, a license import failure time for an import application that the license is intended to activate, when the validity verification of the imported license fails.
In addition, in order to assist the license scheduling module 1010 in implementing the anti-riot import mechanism, the license management apparatus in this embodiment may further include a disable management module (not shown in fig. 10) for detecting a license import failure frequency according to a license import failure time recorded for the import application; when detecting that the license import failure frequency of the import application is higher than a preset threshold value, the equipment main application sets the import application into a license import prohibition state and performs timing maintenance on the license import prohibition state of the import application; when the timing of the prohibited import state of the import application arrives, the device host application releases the prohibited license import state of the import application.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather to enable any modification, equivalent replacement, improvement or the like to be made within the spirit and principles of the invention.
