In one embodiment, the intra-device file identification information and the inter-device file identification information may be uniform resource identifiers.

The first sharing module may add the source device information to the intra-device file identification information to generate inter-device file identification information. For example, the intra-device file identification information is content://media/external/file/1, the source device information is 123456, and the inter-device identification information may be content:123456://media/external/file/1.

204. The first sharing module launches the second application according to the destination device information and the destination application information, and sends the inter-device file identification information to the second application.

It should be understood that, in order to improve the security of data transmission, the first sharing module may encrypt the inter-device file identification information before sending the inter-device file identification information to the second application.

205. The first sharing module sends the inter-device file identification information, the target application information and the operation authority information to the second sharing module according to the target device information.

In this embodiment, the first sharing module transmits the operation authority information to the second sharing module, so that the second sharing module performs the first operation authority check on the file operation of the file to be shared by the second application according to the operation authority information, thereby improving the security of the operation. sex.

In other embodiments, the first sharing module may not transmit the operation permission information to the second sharing module, and the second sharing module does not perform the first operation permission check on the file operation of the file to be shared by the second application.

It should be understood that, in order to improve the security of data transmission, before the first sharing module sends the inter-device file identification information, the purpose application information and the operation authority information to the second sharing module, it can share the inter-device file identification information, purpose application information and operation authority information. The operation authority information is encrypted.

206. The second sharing module identifies whether the file to be shared is an external file according to the identification information of the inter-device file, and returns the identification result of the file to be shared to the second application according to the target application information.

In this embodiment, after receiving the inter-device file identification information from the first sharing module, the second application sends a file identification request to the second sharing module, and after receiving the file identification request, the second sharing module according to the inter-device file The identification information identifies whether the file to be shared is an external file, and the identification result of the file to be shared is returned to the second application according to the target application information.

The second sharing module can parse out the source device information from the inter-device file identification information, and judge whether the file to be shared is an external file according to the parsed source device information. For example, the second sharing module parses the source device information from the inter-device file identification information content:123456://media/external/file/1 as 123456, and 123456 represents the first electronic device rather than the device (ie, the second electronic device), Then it is determined that the file to be shared is an external file.

207. If the file to be shared is an external file, the second application performs the first file operation on the file to be shared through the second sharing module.

The first file operation to be shared with the file may include reading a file, writing a file, sharing a file in a device, and the like.

For example, the second application only has read permission but no write permission to the shared file, and if the first file operation is a write operation, the write operation is rejected.

Performing the first operation authority check in the second electronic device can intercept illegal operations in advance, improve the security of file operations, and can reduce the communication overhead between the first electronic device and the second electronic device during illegal operations.

209, if the first operation authority check is passed, the second sharing module generates a file operation request according to the first file operation, and sends the file operation request to the first sharing module, where the file operation request includes the inter-device file identification information of the file to be shared, the purpose Application information, destination device information, and operation information of the first file operation.

The operation information indicates a first file operation performed by the second application on the shareable file, such as a write operation.

It should be understood that, in order to improve the security of data transmission, the second sharing module may encrypt the file operation request before sending the file operation request to the first sharing module.

210. The first sharing module searches for the corresponding intra-device file identification information and operation authority information according to the inter-device file identification information in the file operation request.

211. The first sharing module performs a second operation authority check according to the found operation authority information and the operation information in the file operation request.

Performing the second operation authority check according to the operation authority information and the operation information may include:

Determine whether the operation type corresponding to the operation information is the specified operation type.

For example, the file operation request indicates that a write operation is to be performed on the file to be shared, and the first electronic device determines whether the second application has the write permission to the shared file according to the operation permission information. If the second application has the write permission to the shared file, the operation type The second operation permission check.

The second operation authority check on the operation information according to the operation authority information may further include:

To operate the file to be shared, pass the second operation permission check of the operation time.

212. If the second operation authority check is passed, the first sharing module performs a second file operation on the file to be shared according to the found file identification information and operation information in the device.

The first sharing module can search the file descriptor of the file to be shared according to the found file identification information in the device, operate the file to be shared according to the found file descriptor and operation information, and return the operation result to the second electronic device.

For example, the first sharing module performs a write operation on the to-be-shared file according to the found file descriptor and operation information.

213. The first sharing module returns the operation result to the second sharing module according to the destination device information in the file operation request.

It should be understood that, in order to improve the security of data transmission, the first sharing module may encrypt the operation result before returning the operation result to the second sharing module.

214. The second sharing module returns the operation result to the second application.

The second application displays the file to be shared according to the operation result. For example, the second application displays the written file to be shared according to the operation result of the writing operation.
