Adding watermark is the most intuitive way to declare sovereignty, but there is no function to insert watermark in PPT. We can do this:
(1) First open PPT, click the [View]-[Master View]-[Slide Master] button to enter the slide master mode.
(2) Click the [Insert]-[Text]-[Text Box] button, then draw a text box and enter text (i.e. watermark content).
(3) Exit the master view and you can see the effect. Every time you create a new page in the future, the watermark will be automatically added.
If you don’t want to show the PPT to others, or don’t want others to edit it. Then the following method is suitable:
(1) Click [File]-[Options]-[Security] option in sequence.
(2) In the interface, choose to set [Open Permission] or [Edit Permission] as required. Opening permissions: You need to enter a password to open the PPT document. Editing permissions: You can view the PPT content, and you need to enter a password to edit the content
