The resource extension method provided in the embodiment of the present application will now be described with reference to fig. 2 to 6.

Fig. 2 is an application scenario architecture diagram provided in an embodiment of the present application. As shown in fig. 2, the application scenario includes a first device, one or more second devices, and a server. The first device and the second device may be the electronic device 100 described above.

The first device may be a master device in which the authorization application may be pre-installed. Wherein the authorized application is a third party application with an authorized License (License). In some embodiments, the authorization application may be authorized for use by the first device in an authorized manner, in which case the authorization application may only be used legally by the first device, and if the program of the authorization application is copied to another device, the program may fail to operate properly due to a failure of the authorization check.

The second device may be a device other than the master device, for example, when the first device resources are limited, the second device may provide the corresponding resources as a support device.

The server may be a server device that provides services for the authorized application. By way of example, the server may be a video server, a music server, a map server, or the like. It will be appreciated that the types of servers described above are merely exemplary and are not limiting to embodiments of the present application, and in some embodiments, other types of servers are also possible.

The server can also perform authorization verification on the data of the authorized application, so that the rights and interests of the authorized application are prevented from being damaged by copying or embezzling the data of the authorized application.

The first device and the second device may be in a distributed environment. Taking the simon system as an example, the first device and the one or more second devices may be in a distributed environment by way of a soft bus, so that the first device and the one or more second devices may be discovered and interconnected with each other. Among other things, soft buses are understood to be a bus technology, and currently common buses may include buses such as peripheral component interconnect (Peripheral Component Interconnect, PCI) buses, control area network (Controller Area Network, CAN) buses, mobile industry processor interface (Mobile Industry Processor Interface, MIPI) buses, integrated circuit (Inter-Integrated Circuit, IIC) buses, and the like. The soft bus can also be called as a distributed soft bus, which is a communication base of distributed equipment such as a mobile phone, a tablet, an intelligent wearable device, an intelligent screen, a car machine and the like, and provides uniform distributed communication capability for interconnection and intercommunication between the equipment. The main functions of the soft bus may include: discovery, connection, networking/topology management, task bus, and data bus. Wherein the "find" function refers to searching whether there are related devices around; "connection" functionality refers to establishing a connection with a discovered device; the networking/topology management function refers to performing network topology management on discovered devices, such as forming a star network topology or forming a Mesh network topology; the task bus function refers to a path for transmitting small data amount information based on the established network topology; the "data bus" function refers to a path for transmitting information of a larger data amount. The first device and the one or more second devices may share the same system account, for example, a hong Monte System, and the first device and the one or more second devices may share the same Monte Account.

In some alternative embodiments, the first device and the second device may also be in a lan environment, where a connection manner of the lan may be a wired connection or a wireless connection, and embodiments of the present application are not limited in particular. The first device may communicate with one or more second devices when the first device is in the same local area network as the one or more second devices.

The embodiment of the application can be applied to a travel cabin scene, for example, a video application is pre-installed on a vehicle of a user, and the video application is authorized to be used. However, when the user downloads other applications on the car, the storage space of the car is insufficient, and thus the video application cannot be opened.

Alternatively, embodiments of the present application may also be applied in a home scenario, for example, where a user purchases a smart screen in which an authorized video application is pre-installed. However, when the user installs other applications in the smart screen, the storage space of the smart screen is insufficient, and thus the video application cannot be opened.

Or, the embodiment of the application may also be applied in the scenes of upgrading games, large tool software and system upgrading, for example, when a user needs to upgrade games, large tool software or system in electronic equipment, because the memory space occupied by the games, large tool software or system is larger, the buffer memory occupied during upgrading is larger, and therefore, when the memory space of the electronic equipment of the user is insufficient, the upgrading of the games, large tool software or system is affected.

Next, the resource expansion method provided in the present application is exemplified below by taking the first device as a car machine and the second device as a mobile phone. Wherein the first device has an authorized application installed therein. It should be understood that the embodiments of the present application are only exemplified by a first device and a second device, that is, one first device is supported by one second device, but the embodiments of the present application are not limited thereto, and in some embodiments, a plurality of second devices may also support one first device.

As shown in fig. 3, a flow chart of an embodiment of a resource expansion method provided in the present application specifically includes the following steps:

in step 301, when the first device detects that the authorized application cannot be normally operated due to limited resources, the second device is discovered.

In particular, the resource limitation may be a limitation of storage resources, for example, the storage space is insufficient, which may cause that the authorized application cannot be normally opened due to insufficient cache space when the first device opens the authorized application, so that the user cannot normally use the authorized application.

In some alternative embodiments, the resource limitation may also be a hardware resource limitation, which may be, for example, a hardware damage, thereby possibly resulting in an inability to open the authorized application normally, or an inability of the user to use the authorized application even after the authorized application is opened. Taking hardware as a camera as an example, the limited hardware resource can be the damage of the camera. If the camera is damaged, an authorized application such as a photographing application using the camera cannot normally run, and thus a user cannot normally use the authorized application such as the photographing application to perform operations such as photographing.

After the first device detects that the authorized application cannot be used due to limited resources, the first device can search to find whether the second device exists in the periphery, so that whether supportable devices exist can be determined. The second device may be discovered through a soft bus, or may be discovered through a local area network, which is not limited in this embodiment of the present application.

In step 302, a first device establishes a connection with a second device.

Specifically, when the first device discovers the second device, a connection request may be sent to the second device for establishing a connection with the second device.

It will be appreciated that if there are a plurality of second devices around the first device, the first device may also establish a connection with the plurality of second devices after discovering the plurality of second devices.

In some alternative embodiments, a connection may be established between the plurality of second devices, so that when any device between the plurality of second devices cannot use the authorized application due to limited resources, a supporting device may be found, and thus efficiency of resource expansion may be improved.

In step 303, the first device requests resource information from the second device.

Specifically, after the first device establishes a connection with the second device, a resource information request may be sent to the second device for requesting resource information. The resource information may include: and storing the resource information such as the space and hardware.

By way of example, the hardware resource information may include information of a hardware category, a hardware model, etc., and the hardware may include, for example: the hardware such as the camera, the gyroscope, the sensor and the like, and it is understood that the hardware may also comprise other types of hardware, which are not exemplified herein. The resource information of the second device is acquired by the first device, and the supporting device can be selected according to the resource information of the second device, so that the problem of limited resources of the first device can be effectively solved.

In some optional embodiments, the first device may also send the resource information to the second device, and acquire the resource information of the first device through the second device, and may select the first device as the supporting device when the resource of the second device is limited, so that the problem that the resource of the second device is limited may be effectively solved.

In some alternative embodiments, the first device may obtain the reference information in addition to requesting the resource information from the second device. The reference information is used to characterize the state of the second device. The reference information may be used as a reference factor for determining the support device among the one or more second devices.

The reference information may include, for example: the system account number of the second device, the connection mode of the first device and the second device, the transmission speed of the first device and the second device, the distance between the first device and the second device, the position of the second device, the system of the first device and the second device, the signal intensity of the second device and the like. It will be appreciated that the types of reference information described above are merely exemplary and are not limiting to embodiments of the present application, and that in some embodiments, more or fewer types of reference information may be included.

The system account may be an account for logging in the electronic device system, for example, a hong Monte System, and after the user logs in the hong Monte System using the hong Monte Account, the electronic device logged in by the user may be one distributed device in the hong Monte System, may be found by other distributed devices in the hong Monte System, or may be found by other distributed devices in the hong Monte System.

The connection mode may be a connection mode between devices. The connection mode can be wired or wireless. The wireless means may include soft bus, bluetooth, or wireless fidelity (Wireless Fidelity, wi-Fi), etc. It will be appreciated that the wireless means described above may also include other types of means, not to be limiting.

The transmission speed may be a data transmission speed. When the first device establishes a connection with the second device, a data test may be performed, for example, test data may be sent to the second device, so as to obtain a transmission speed between the first device and the second device.

The distance refers to a distance between devices, and may include a distance between a first device and one or more second devices, or may include a distance between the second devices.

The above-mentioned position refers to the relative position where the second device and the first device are located. In the travel cabin scene, whether the first device and the second device are in the same vehicle or different vehicles can be determined through signal strength judgment. It can be understood that the metal shell of the vehicle has a strong shielding effect on signals, if the first device and the second device are in a different-vehicle scene, after the first device and the second device are connected, the signal intensity of the second device detected by the first device has a cliff-like drop, and at this time, the signal intensity of the second device detected by the first device is weaker.

The system refers to the operating system used by the device. By way of example, the operating system may include systems such as android, hong, and the like.

The signal strength may be the strength of a wireless signal when the device is in a wireless connection. The wireless connection may include, for example, wi-Fi, bluetooth, etc.

In some alternative embodiments, the second device may also request resource information from other devices (e.g., the first device and the remaining second devices) and obtain reference information. The method for the second device to request the resource information and obtain the reference information may refer to the method for the first device to request the resource information and obtain the reference information, which is not described herein. The second equipment requests the resource information and acquires the reference information, so that when the second equipment cannot use the authorized application due to limited resources, the support equipment can be timely determined in other equipment according to the resource information and the reference information, and the efficiency of resource expansion can be improved.

The second device sends the resource information to the first device, step 304. And the corresponding first equipment receives the resource information sent by the second equipment.

In step 305, the first device determines, according to the resource information of the second device, a supporting device, where the supporting device provides the resources required by the first device.

Specifically, after the first device acquires the resource information of the second device, the supporting device may be determined according to the resource information of the second device.

For example, if the first device is limited in storage resources and the second device has free storage resources, the first device may use the second device as a support device and use the storage space of the second device as an assist, so that the first device may use the above-mentioned authorized application.

If the first device is limited in hardware resources, the second device can provide corresponding hardware, and the first device can use the second device as a supporting device and use the hardware of the second device as an auxiliary device, so that the first device can use the authorized application.

It will be appreciated that the number of support devices may be one or more. If the first device establishes a connection with a second device, the number of support devices may be one, that is, the first device may use the second device that establishes a connection with the first device as a support device; if the first device establishes a connection with a plurality of second devices, the number of support devices may be one or more, that is, the first device may select one or more second devices from the plurality of second devices that establish a connection with the first device as support devices.

In some alternative embodiments, in order not to affect the operation of the second device, in selecting the supporting device from the second device, the operation situation after the second device performs the supporting may also be considered.

For example, if the first device is limited in storage resources, after the second device supports the storage resources of the first device, the storage usage rate of the second device reaches a higher value, for example, reaches 100%, which may cause the second device to be blocked, and the first device may not use the second device as a support device.

Alternatively, if the first device is limited in hardware resources, for example, the camera of the first device is bad, and the second device is performing video call, at this time, if the second device supports the camera for the first device, the video call in the second device may fail, so in this scenario, the first device may not use the second device as a support device.

In some alternative embodiments, if a first device is connected to a plurality of second devices and the first device is limited to a type of resource, for example, limited storage resources or limited hardware resources, then one of the plurality of second devices may be selected as a support device. The method for selecting the support device from the plurality of second devices may be based on the reference information and the resource information of the second devices.

The selection algorithm of the support apparatus will now be exemplarily described with reference to fig. 4. Referring to fig. 4, after the first device obtains the reference information and the resource information of the plurality of second devices, each parameter and the resource information in the reference information of each second device may be scored, where the parameters may be parameters such as a system account number of the second device, a location of the second device, a connection manner of the first device and the second device, a transmission speed of the first device and the second device, a distance between the first device and the second device, a system of the first device and the second device, and a signal strength of the second device.

Taking the resource information of the second device as an example, if the hardware type and the hardware model provided by the second device are the same as the resources required by the first device, the score of the resource information of the second device is higher, and if the hardware type and the hardware model provided by the second device are not the same as the resources required by the first device, the score of the resource information of the second device is lower; and/or the more sufficient the storage resources provided by the second device, the higher the score of the resource information of the second device, and the less the storage resources available to the second device, the lower the score of the resource information of the second device.

Or taking the system account number of the second device as an example, if the system account number of the first device is the same as the system account number of any second device, the score of the system account number parameter of the second device is higher; if the system account numbers of the first device and any one of the second devices are different, the score of the system account number parameter of the second device is lower.

Or taking the position of the second device as an example, if the first device and any second device are determined to be in the same scene, the score of the position parameter of the second device is higher; if the first equipment and any second equipment are determined to be in the different-car scene, the score of the position parameter of the second equipment is lower.

Or taking the connection mode of the first device and the second device as an example, if the connection mode of the first device and any one of the second devices is wired connection, the score of the connection mode parameter of the second device is higher, and if the connection mode of the first device and any one of the second devices is wireless connection, the score of the connection mode parameter of the second device is lower.

Or taking the transmission speeds of the first device and the second device as an example, if the transmission speeds of the first device and any one of the second devices are higher, the score of the transmission speed parameter of the second device is higher; if the transmission speeds of the first device and any second device are slower, the score of the transmission speed parameter of the second device is lower.

Or taking the distance between the first device and the second device as an example, if the distance between the first device and the second device is relatively close, the score of the distance parameter of the second device is relatively high; if the first device is farther from the second device, the distance parameter of the second device has a lower score.

Or taking the signal intensity of the second device as an example, if the connection mode of the first device and any second device is wireless connection, the stronger the signal of the second device is, the higher the score of the signal intensity parameter of the second device is; the weaker the signal of the second device, the lower the score of the signal strength parameter of the second device.

Or taking the system of the first equipment and the second equipment as an example, if the system of the first equipment is the same as the system of any second equipment, the score of the system parameter of the second equipment is higher; if the system of the first device is not the same as the system of any second device, the score of the system parameter of the second device is lower.

Therefore, the first device can preferentially select the second device which has sufficient resources, is the same as the first device in hardware type and signal, is connected with the first device system account and/or is in wired connection with the first device, is close to the first device and/or is in a same-vehicle scene with the first device, is strong in signal and/or is fast in transmission speed with the first device from the plurality of second devices as the supporting device.

In addition, in addition to scoring the parameters in the resource information and the reference information, a corresponding weight coefficient may be set for each parameter in the resource information and the reference information, so that statistics may be performed on the resource information and the reference information in each second device. For example, the statistical manner may be that each parameter in the resource information and the reference information in each second device is weighted, so that a final score of each second device may be obtained statistically, and thus a supporting device may be determined according to the final score of each second device, for example, the supporting device may be the second device with the highest score.

In some alternative embodiments, if a first device is connected to a plurality of second devices and the first device is limited to one type of resource, e.g., storage resources are limited or hardware resources are limited, the plurality of second devices may be selected as support devices from the plurality of second devices, and the amount of support resources for each resource device may be determined.

For example, taking a storage resource as an example, if the storage resource required by the first device is larger, the storage resource available to one second device is insufficient to meet the storage resource required by the first device, at this time, the first device may select a plurality of second devices as supporting devices, so that the sum of the storage resources available to the plurality of second devices meets the storage resource required by the first device.

The first device selects a plurality of second devices as supporting devices in the following manner: the second devices with more abundant free resources may provide a larger proportion of memory resources and the second devices with less free resources may provide a smaller proportion of memory resources. When the second device is selected as a support device and the available resources of the support device are determined, a preset condition may be set, which may be used to characterize the maximum available resources of the second device. Taking the storage resource as an example, the preset condition of the second device may be 80%, that is, after the second device supports the storage resource of the first device, the occupancy rate of the storage resource in the second device cannot exceed 80%, so that the second device can be ensured to operate smoothly without being blocked. It will be appreciated that the above-described storage resource occupancy values of 80% are merely exemplary and are not limiting to embodiments of the present application, and in some embodiments, the above-described storage resource occupancy values may be other values.

For example, assuming that the first device needs 100M storage resources, first, if the idle storage resources of the second device a are sufficient, the available maximum storage resource is 50M, the second device a may be used as a supporting device, and it may be determined that the second device a supports 50M storage resources; secondly, if the idle storage resource of the second device B is the next time, the available maximum storage resource is 30M, the second device B may be used as a supporting device, and it may be determined that the second device B supports 30M storage resources; then, if the idle memory resource of the second device C is again 20M, the second device C may be used as a supporting device, and it may be determined that the second device C supports 20M memory resource. After the first device selects the second device a, the second device B, and the second device C as the supporting devices, the sum of the storage resources available to the second device a, the second device B, and the second device C is 100M, and the storage resources 100M required by the first device are already satisfied, at which point the first device may stop the selection of the supporting devices.

Alternatively, the manner in which the first device selects the plurality of second devices as the supporting devices may be: a higher priority second device may provide a greater proportion of storage resources and a lower priority second device may provide a lesser proportion of storage resources. The priority level may be determined by a support device selection algorithm as shown in fig. 4. For example, the second device with the higher final score has a higher priority and the second device with the lower final score has a lower priority.

For example, assuming that the first device needs 100M storage resources, first, if the priority of the second device a is higher, the available maximum storage resource is 20M, the second device a may be used as a supporting device, and it may be determined that the second device a supports 20M storage resources; secondly, if the priority of the second device B is 30M, the second device B may be used as a supporting device, and it may be determined that the second device B supports 30M storage resources; then, if the priority of the second device C is again the maximum available storage resource is 50M, the second device C may be used as a support device, and it may be determined that the second device C supports the 50M storage resource. After the first device selects the second device a, the second device B, and the second device C as the supporting devices, the sum of the storage resources available to the second device a, the second device B, and the second device C is 100M, and the storage resources 100M required by the first device are already satisfied, at which point the first device may stop the selection of the supporting devices.

In some alternative embodiments, if the first device is connected to a plurality of second devices and the first device is limited by multiple types of resources, for example, limited storage resources, limited hardware resources, and the like, the plurality of second devices may be selected as support devices from the plurality of second devices.

For example, assuming that the first device needs both storage resources and hardware resources, if the second device a may provide storage resources and the second device B may provide hardware resources, the first device may select the second device a and the second device B as support devices.

It may be appreciated that, when the first device is limited to multiple types of resources, if the available resources of one second device are not enough to meet any type of resources required by the first device, the resources of the multiple second devices may be selected to meet any type of resources required by the first device, where a manner of selecting the resources of the multiple second devices to meet any type of resources required by the first device may be specifically referred to the related description in the foregoing embodiments, which is not repeated herein.

In step 306, the first device runs the authorization application according to the resource provided by the support device, wherein the authorization scope of the authorization application is unchanged.

Specifically, after the first device determines the supporting device, the above-mentioned authorized application may be executed according to the resource provided by the supporting device, for example, the authorized application may be notified that the resource required by the authorized application is sufficient, and thus the first device may be caused to execute the authorized application. It can be understood that when the resource provided by the supporting device is used, the authorization range of the authorized application is not changed, so that the authorized application which cannot be operated due to the limited resource can be opened through the resource supported by the peripheral device under the condition that the authorization range is not changed, and the use experience of the user can be improved.

Taking the resource provided by the supporting device as a hardware resource as an example, after the first device determines the supporting device, the first device may send a resource usage request to the supporting device for using the hardware resource in the supporting device. Accordingly, after the support device receives the resource use request sent by the first device, the support device can open corresponding hardware in the support device for the authorized application of the first device to use, so that the authorized application can run smoothly.

Alternatively, taking the resource provided by the support device as the storage resource as an example, the first device may send the cache data to the support device after determining the support device. The cached data may be data that is required to be cached for opening the authorized application. Accordingly, the support device may store the buffered data in the support device after receiving the buffered data sent by the first device, so that the buffered data is sent to the first device when the first device requests the buffered data.

In the embodiment of the application, the main device requests the resource from the peripheral device under the condition of limited resource, so that the main device can smoothly run the authorized application under the condition of not changing the authorized range of the authorized application, and the use experience of a user can be improved.

The above exemplary resource expansion manner is illustrated by fig. 2 to fig. 4, and by the above resource expansion manner, an authorized application that cannot be normally operated due to resource limitation can be smoothly operated under the condition that the first device resource is limited. However, for a scenario in which storage resources are limited, in the process that the first device sends the cached data to the supporting device, in order to avoid that the cached data is used in infringement, the cached data may also be protected.

Fig. 5 is a flowchart of another embodiment of the resource extension method provided in the present application, and in order to protect the cached data, the step 304 may further include the following steps:

in step 501, a first device generates a key.

Specifically, in order to ensure the security of the cached data, the key may be randomly generated without being hacked by the support device. The key may be a symmetric key, that is, the support device does not store the key, so that the security of the cached data may be ensured. The first device may not only encrypt with the key, but also decrypt with the key.

It is understood that the encryption key may be in the form of a number, a character, a combination of numbers or characters, which is not particularly limited in the embodiments of the present application.

In step 502, the first device encrypts the buffered data using the key to obtain encrypted buffered data.

Specifically, after the first device generates the key, the cached data may be encrypted using the key, whereby the encrypted cached data may be obtained. The cache data may be data that cannot be stored in the first device due to insufficient storage resources.

It will be appreciated that the encryption algorithm for encrypting the buffered data may refer to existing encryption algorithms, such as: data encryption standard (Data Encryption Standard, DES), RC2, RC4, international data encryption algorithm (International Data Encryption Algorithm, IDEA), advanced encryption standard (Advanced Encryption Standard, AES), etc., to which the embodiments of the present application are not particularly limited.

In step 503, the first device sends the encrypted cache data to the support device. Correspondingly, the support device receives and stores the encrypted cache data sent by the first device.

Specifically, after the first device obtains the encrypted cache data, the encrypted cache data may be sent to the supporting device, so that the supporting device may store the encrypted cache data, and the storage space of the first device is not occupied.

Because the support device only stores the encrypted cache data and does not have the key generated by the first device, the encrypted cache data cannot be decrypted, so that the security of the cache data can be ensured, and the legal rights and interests of authorized applications can be ensured.

In step 504, the first device sends a query request to the support device. Correspondingly, the support device receives the query request sent by the first device.

Specifically, when the first device has a service requirement of the authorized application, a query request may be sent to the supporting device to obtain the corresponding cache data, so that the authorized application may run smoothly, and thus, the user may use the authorized application smoothly to enjoy the service provided by the authorized application. For example, taking a map application as an example, when a user needs to navigate, the first device may send a query request to the support device for requesting to cache data, so that the map application may smoothly navigate, thereby enabling the user to enjoy the navigation service.

It will be appreciated that the query request may be used to query all of the cached data, or may query some of the cached data, that is, the queried data may be based on business requirements. Therefore, in some optional embodiments, in step 503, the first device may further perform index identification on the cached data in the process of sending the encrypted cached data to the support device, so that the first device may be convenient to query the cached data.

In some optional embodiments, when the first device performs index identification on the cached data, if the cached data is stored in the plurality of support devices, the cached data may also be bound with a device identifier, where the device identifier is used to distinguish a device, so that the first device may quickly obtain corresponding data when requesting the data, and avoid a decrease in efficiency of querying the data caused by unclear storage devices of the cached data, thereby resulting in a decrease in operation efficiency of the authorized application.

In a specific implementation, the first device may establish a mapping table of the cache data and the supporting device, where the mapping table is used to characterize a mapping relationship between the cache data and the supporting device, and when the first device needs to request the cache data, the supporting device corresponding to the cache data to be queried may be queried according to the mapping table.

Table 1 is a mapping table of the cache data and the supporting device.

TABLE 1

Caching data index	Device identification
		Caching data 1	Support apparatus 1
Caching data 2	Support apparatus 2
		Caching data 3	Support apparatus 2

Referring to table 1, taking the example of dividing the cache data into 3 parts of cache data 1, cache data 2 and cache data 3, if the first device stores the cache data 1 in the support device 1, the cache data 1 may be mapped with the support device 1; if the first device stores the cached data 2 in the supporting device 2, the cached data 2 may be mapped with the supporting device 2; if the first device stores the cache data 3 in the support device 2, the cache data 3 may be mapped with the support device 2. That is, one or more portions of the buffered data may be stored in a support device, which is not particularly limited in the embodiments of the present application.

Wherein, when storing the divided cache data in the supporting device, the cache data of a plurality of continuous parts can be stored in the same supporting device;

alternatively, the plurality of discontinuous portions of the buffered data may be stored in the same supporting device, which is not particularly limited in the embodiment of the present application.

It will be appreciated that the above-described manner of dividing the cache data to obtain the plurality of portions is merely illustrative and not limiting of embodiments of the present application, and in some embodiments the cache data may be divided into more or less portions.

In step 505, the support device sends, to the first device, encrypted cache data corresponding to the query request based on the query request. Correspondingly, the first device receives encrypted cache data corresponding to the query request sent by the supporting device.

Specifically, when the support device receives the query request, the encrypted cache data may be queried based on the query request, so that the encrypted cache data corresponding to the query request may be obtained, and after the encrypted cache data corresponding to the query request is obtained, the encrypted cache data corresponding to the query request may be sent to the first device.

It will be appreciated that the buffered data transmitted by the support device is also encrypted, thereby ensuring the security of the buffered data against theft or eavesdropping during transmission.

In step 506, the first device decrypts the encrypted cache data corresponding to the query request and uses the decrypted cache data.

Specifically, after the first device receives the encrypted cache data corresponding to the query request sent by the support device, the first device may decrypt the encrypted cache data corresponding to the query request, thereby obtaining the cache data, so that the authorized application may run smoothly.

After the first device obtains the cached data, the cached data and other related data are used to interact with the server, so that a specific process of enabling the user to enjoy the service provided by the authorized application can refer to an existing process, which is not described herein.

In the embodiment of the application, the buffer data is encrypted, so that the buffer data cannot be cracked and stolen after being sent to the supporting equipment, the security of the authorized application can be ensured, and the legal rights and interests of the authorized application are maintained.

The protection of cached data is illustrated above by way of example in fig. 5. Next, authorization verification by the support apparatus will be described with reference to fig. 6. The authorization may be verified during the process of providing services to the first device by the authorization application. Since the storage resource used by the cache data is provided by the supporting equipment, when the authorization verification is performed, the equipment information of the supporting equipment is acquired, so that the authorization verification is failed, the service of the authorized application is stopped, and the service experience of the user is affected.

Fig. 6 is a flowchart of still another embodiment of the resource extension method provided in the present application, and in order to avoid a verification failure in the authorization verification of the authorized application, the step 304 may further include the following steps:

in step 601, the first device sends first device identity information to the support device. Correspondingly, the supporting device receives the first device identity information sent by the first device.

Specifically, when the first device determines the supporting device, the first device identity information may also be sent to the supporting device. The first equipment identity information is used for identifying software and hardware identification information of the first equipment. The first device identity information may be, for example, a device serial number of the first device, or may be other types of identity identifiers, which is not limited in particular in the embodiments of the present application.

In the scenario where the limited resource is a storage resource, the manner in which the first device sends the first device identity information to the supporting device may be:

the first device sends cache data and first device identity information to the supporting device at the same time;

or after the first device sends the cache data to the supporting device, the first device sends the first device identity information to the supporting device;

Or after the first device sends the first device identity information to the supporting device, the first device sends the cache data to the supporting device.

The buffer data sent by the first device to the supporting device may be encrypted or unencrypted, which is not limited in the embodiment of the present application.

In step 602, the supporting device binds the encrypted cache data with the first device identity information.

Specifically, after the supporting device receives the encrypted cache data and the first device identity information, the encrypted cache data may be bound with the first device identity information.

It will be appreciated that the second device also has its own identity information, e.g. second device identity information. For convenience of explanation, the second equipment identity information of the supporting equipment may be referred to as supporting equipment identity information. Therefore, in the supporting device, the first device identity information and the supporting device identity information may be respectively bound with different data, for example, the encrypted cache data and the first device identity information are bound, and the data of the authorized application of the supporting device is bound with the supporting device identity information, so that the supporting device does not influence the authorization check of the encrypted cache data or the authorization check of the authorized application of the supporting device.

In a specific implementation, a mapping table of data and equipment identity information may be stored in the supporting equipment, where the mapping table is used to characterize a mapping relationship between the stored data and the equipment identity information.

Table 2 is a mapping table of data and device identity information.

TABLE 2

Data	Device identity information
		Encrypting cached data	First device identity information
Data supporting self-authorizing applications of devices	Supporting device identity information

Referring to table 2, the supporting device includes first equipment identity information and supporting equipment identity information, wherein the first equipment identity information and the supporting equipment identity information correspond to encrypted cache data and data of an authorized application of the supporting device, respectively, for example, the first equipment identity information corresponds to the encrypted cache data, and the supporting equipment identity information corresponds to the data of the authorized application of the supporting device. By the mapping relation, the supporting equipment identity information can be fed back when the data of the self-authorized application in the supporting equipment is subjected to authorization verification, and the first equipment identity information can be fed back when the encrypted cache data in the supporting equipment is subjected to authorization verification.

In step 603, the authorization application sends an authorization check request to the support device, for requesting authorization check of the encrypted cache data. Accordingly, the support device receives an authorization verification request sent by the authorization application.

Specifically, when the authorization application needs to perform authorization verification on any device, the device may be requested to acquire device identity information.

If the authorization application performs authorization verification on the data of the authorization application stored in the first device, the first device may feed back the first device identity information, and since the authorization application is only authorized for the first device, the authorization verification can be determined to pass through the authorization verification on the first device identity information.

It may be understood that the authorization verification may be performed on the first device identity information by the server, and a specific authorization verification manner may refer to an existing authorization verification procedure, which is not described herein.

If the authorization application performs authorization verification on the encrypted cache data stored in the support device, the authorization application may send an authorization verification request to the support device for requesting authorization verification on the encrypted cache data. By verifying the authorization of the encrypted cache data, the damage to the rights and interests of the authorized application caused by the theft of the data can be avoided.

The support device sends the first device identity information to the authorized application, step 604. Correspondingly, the authorization application receives the first equipment identity information sent by the supporting equipment.

Specifically, after receiving the authorization verification request, the support device may send corresponding device identity information based on the authorization verification request.

For example, if it is determined that the authorization check request is to perform authorization check on data of an authorized application of the support device itself, the support device may send support device identity information to the requested authorized application.

If it is determined that the authorization check request is for performing authorization check on the encrypted cache data sent by the first device, the support device may send first device identity information to the requested authorization application.

In step 605, the authorization application performs authorization verification based on the first device identity information sent by the support device.

Specifically, after the authorization application receives the first equipment identity information sent by the supporting equipment, authorization verification may be performed based on the first equipment identity information. Since the authorization application is installed in the first device and is only authorized to the first device. Therefore, when the authorization application performs authorization verification, only the first device identity information is transmitted to pass the authorization verification. In this scenario, the first device sends the first device identity information to the supporting device in advance, so that the supporting device can feed back the first device identity information instead of feeding back the supporting device identity information when receiving the authorization check request, thereby successfully completing authorization check and avoiding failure in checking caused by feeding back the supporting device identity information.

In the embodiment of the application, the first equipment sends the first equipment identity information to the supporting equipment, so that the authorization check of the encrypted cache data can be successfully completed when the authorization application performs the authorization check, the authorization application can be smoothly operated, the interruption of the authorization application service caused by the failure of the authorization check is avoided, and the use experience of a user can be improved.
