With the advent of the era of big data, no matter any data, information, and documents are becoming more and more important to individuals and businesses.
When I worked so hard to design a beautiful PPT, it was stolen by others and became unrecognizable; or when the PPT contained important information about the company and did not want to be seen by others and leaked the information… These times, our first thought I just want to protect my PPT.
How to protect it? Today, I use an article to let you master a few simple techniques for protecting PPT files, and bid farewell to the abuse of PPT by others and the disclosure of important information.
1. Add watermark
Many people should know that there is no function of inserting watermark in PPT. If we want to add watermark to PPT to prove our copyright, then you can do so.
(1) First open the PPT, click [View]-[Master View]-[Slide Master] button to enter the slide master mode.
(2) Click the [Insert]-[Text]-[Text Box] button, and then draw a text box and enter the text (ie watermark content).
(3) Exit the master view, you can see the effect. After each new page is created, the watermark will be added automatically.
Tips: You can also insert pictures or artistic words as watermarks in PPT.
If the PPT you make is a company secret, you do not want to show the PPT to others, or when you send the PPT to others, you do not want others to edit it. Then you must master the following 2 methods to protect PPT.
1. Encrypt with a password
After encrypting the PPT file with a password, if there is no password for the method, the PPT cannot be opened and the content in the PPT cannot be seen.
(1) Click the [File]-[Information]-[Protect Presentation] button in turn, and select the “Encrypt with Password” command in the pop-up menu.
(2) At this time, a dialog box prompting to encrypt the file will pop up, enter the password, and click the “OK” button.
(3) When you open the PPT again, you are prompted to enter a password. After completion, you can see the “Protect Presentation” column is displayed in yellow, indicating that the current PPT has been protected.
2. Set authority password
After setting the authority password for the PPT, others can only view the PPT, but not edit it. You can edit it only after entering the correct password.
(1) Click the [File]-[Save As]-[Browse] button to open the “Save As” dialog box, click the “Tools” button, and select the “General Options” command in the pop-up menu.
(2) Then this page pops up, enter the modification authority password and confirm the password.
(3) When the PPT file is opened again, it can be edited if the correct password is entered, otherwise it will be opened as “read only”.
