Optionally, in this embodiment of the application, a user may trigger the electronic device to display at least one editing control (e.g., a copy control, a cut control, a paste control, and the like) corresponding to the target content through input, so that the user may perform a first input on a target control (e.g., a copy control or a cut control) of the at least one editing control.
Optionally, in this embodiment of the application, when the electronic device receives the first input of the user, the target content and the first biometric information of the user may be acquired at the same time.
Optionally, in this embodiment of the application, the first biometric information may be any one of: fingerprint information, face information, iris information, etc.
Optionally, in this embodiment of the application, in a case that the first biometric information is fingerprint information, the electronic device may acquire the fingerprint information of the user through screen recognition while the user performs a first input (for example, a user clicks a copy control displayed in a screen).
It should be noted that, when the user performs the first input, the user needs to click on the screen of the electronic device with a finger (that is, the finger of the user makes contact with the screen of the electronic device), so that the electronic device can acquire the first biometric information (that is, the fingerprint information) of the user through the screen.
Optionally, in this embodiment of the application, in a case that the first biometric information is face information or iris information, the electronic device may acquire the face information or iris information of the user through the camera while the user performs the first input (for example, a click input of the user on a copy control displayed in the screen).
And 203, under the condition that the first biological characteristic information is matched with the preset characteristic information, the electronic equipment encrypts the target content and stores the encrypted target content in a first storage area corresponding to the preset characteristic information.
In this embodiment, the first storage area is used to store encrypted copied content or cut content.
In the embodiment of the application, the electronic device can judge whether the acquired first biological characteristic information is matched with the preset characteristic information, so that the electronic device processes the target content under the condition that the first biological characteristic information is matched with the preset characteristic information.
Optionally, in this embodiment of the application, matching the first biometric characteristic information with the preset characteristic information may be understood as: the similarity between the first biological characteristic information and the preset characteristic information is greater than or equal to the preset similarity.
Optionally, in this embodiment of the present application, the electronic device may include at least two preset areas for storing different types of content, where the at least two preset areas include the first storage area described above and a second storage area described below.
Optionally, in this embodiment of the present application, the first storage area and the second storage area may both be storage areas corresponding to a clipboard in an electronic device, where the first storage area may be a private clipboard, and the second storage area may be a public clipboard.
It should be noted that the different types of content may be understood as content corresponding to different types of users, that is, a user whose biometric information matches with the preset feature information is a first type of user (corresponding to the first type of content), a user whose biometric information does not match with the preset feature information is a second type of user (corresponding to the second type of content), and different users may correspond to different preset feature information, so that different users may correspond to different first storage areas, that is, when different users input the electronic device, the electronic device may store the encrypted content in different first storage areas.
It can be understood that, the first storage area is an encryption area, and when the target content is private content or important content, the electronic device may encrypt the target content according to the biometric information of the user and then store the encrypted target content in the first storage area corresponding to the preset feature information, so that other users do not view or use the target content, and thus leakage of the target content can be prevented.
The embodiment of the application provides a content encryption method, because when a user inputs target content, an electronic device can first acquire the target content and first biological characteristic information of the user, then, under the condition that the first biological characteristic information is matched with the preset characteristic information, the first biological characteristic information is adopted to encrypt the target content, to store the encrypted target content in a specific storage area corresponding to the preset characteristic information (i.e., an area storing the encrypted copy content or the cut content), instead of directly storing the target content in a default area in the electronic device, so that other users cannot directly use the encrypted copied contents or cut contents in the electronic device, therefore, the possibility of target content leakage can be reduced, and the safety of the electronic equipment is higher.

Optionally, in this embodiment of the application, the fact that the first biometric information is not matched with the preset feature information may be understood as: the similarity between the first biological characteristic information and the preset characteristic information is smaller than the preset similarity.
It can be understood that the second storage area is an unencrypted area, and when the target content is normal content (i.e. unimportant content), the electronic device does not need to encrypt the target content, but directly stores the target content in the second storage area, i.e. when the biometric information of the user does not match the preset feature information, the electronic device does not need to encrypt the target content, but directly stores the target content in the second storage area.
In the embodiment of the application, the electronic device can judge whether the first biological characteristic information is matched with the preset characteristic information, so that when the first biological characteristic information is not matched with the preset characteristic information, the electronic device directly stores the target content into the second storage area without encrypting the target content, and therefore the electronic device can flexibly judge the storage area of the target content, and accordingly the storage area of the target content is determined.

Optionally, in this embodiment of the application, the second biometric information may be any one of: fingerprint information, face information, iris information, etc.
Optionally, in this embodiment of the application, in a case that the second biometric information is fingerprint information, the electronic device may acquire the fingerprint information of the user through screen recognition while the user performs a second input (for example, a click input of the user on a copy control displayed in the screen).

Optionally, in this embodiment of the application, in a case that the second biometric information is face information or iris information, the electronic device may acquire the face information or iris information of the user through the camera while the user performs a second input (for example, a click input of the user on a copy control displayed in the screen).
And step 304, under the condition that the second biological characteristic information is matched with the preset characteristic information, the electronic equipment decrypts the target content stored in the first storage area, and pastes the decrypted target content.
In this embodiment of the application, the electronic device may determine whether the acquired second biometric information matches the preset feature information, so that the electronic device processes the target content when the second biometric information matches the preset feature information.
Optionally, in this embodiment of the application, matching the second biometric information with the preset feature information may be understood as: the similarity between the second biological characteristic information and the preset characteristic information is greater than or equal to the preset similarity.
Optionally, in this embodiment of the application, the electronic device may perform decryption processing on the target content stored in the first storage area, so as to paste the decrypted target content to the corresponding area.

Optionally, in this embodiment of the application, the electronic device may paste the decrypted target content in a corresponding area, so as to display the target content in the area.
In the embodiment of the application, when the acquired first biological characteristic information of the user is matched with the preset characteristic information, the electronic device can generate a second key according to the second biological characteristic information, decrypt the target content by using the second key, and paste the decrypted target content in the corresponding area, so that the electronic device can decrypt the target content when the first biological characteristic information of the user is matched with the preset characteristic information, thereby preventing other users from viewing or using the target content, and improving the safety of the electronic device.
In this embodiment, the first content is a history copy content or a history cut content, and the second storage area is used to store the copy content or the history cut content that is not encrypted.
Optionally, in this embodiment of the application, when the second biometric information does not match the preset feature information, the electronic device may not perform a paste operation on the target content stored in the first storage area, and may perform a paste operation on the first content stored in the second storage area.
