As shown in fig. 1, a clipboard control method provided in an embodiment of the present invention is applied to a first application, and the method specifically includes the following steps:
The first application program is a packaged application program, specifically, the attribute and implementation details of the first application program are hidden, and only the interface is externally disclosed to control the access level of reading and modification in the attribute.
When the first application program receives a preset copy instruction carrying a target object, for example, when a user wants to copy the target object in the first application program to a system clipboard of a terminal where the first application program is located, a long-press operation or other operation triggering a copy instruction may be performed on the target object, and when the first application program detects the operation, it is determined that the preset copy instruction for the target object is received.
Further, the clipboard provides an area for the operating system to centrally store data so that applications can share data with each other. The user can copy a copy of data in a certain program, and paste the data into the next program after switching to the next program; and most operating system clipboards have functions similar to cut, copy, paste operations.
When the first application program receives the preset copying instruction, the preset clipboard preset in the first application program is called, the preset clipboard is compatible with the system clipboard of the terminal where the first application program is located, and the function of the system clipboard can be executed by simulating the system clipboard in the first application program through the preset clipboard.
And 102, copying the target object into the preset clipboard, and acquiring a key value of the target object in the preset clipboard.

For example, referring to fig. 2, a first application program writes a target object and a key value into a system clipboard after encrypting the target object and the key value respectively; a second application program and a third application program of the same terminal detect that the key value of the system clipboard is updated; the second application program is used as a packaging application program, a target object and a decryption algorithm of the key value are predicted, the key value is decrypted to obtain ciphertext data, the ciphertext data are further decrypted, the plaintext target object and the key value are restored, and the second application program can copy and paste the target object.
