As HR, you need to give several resumes to the employing department, but you want to hide sensitive information such as the contact number, email address and home address of the applicant.
In external training, you want to use a PDF document as a case teaching material, but you want to hide the sensitive information of the company …
If it is Word, we can directly delete the information that we don't want to deliver; If it is a picture, we can use PS or Meitu Xiu Xiu and other tools to encode the picture. So how do we mosaic the PDF, a seemingly invulnerable guy?

What most people think of is to export a PDF into a picture and then encode the picture? Then talk about picture packaging and delivery. This scheme is divided into four steps: exporting pictures-encoding processing-compression and packaging-file delivery. After the documents are delivered to others, you have to open the pictures one by one. This is the "worst policy".
Others think of tagging PDF (it is estimated that only a wonderful person like me can think of it), such as Evernote or the PDF tagging tool of Microsoft Edge browser:
However, these marks can go wherever they come from-they can be erased by repeatedly using the eraser in the marking tool, and the symptoms will not be cured.

In fact, many software vendors (such as Adobe, PDFelement, Fuxin) have put forward a mature solution to the demand of "checking the sensitive content of documents or tracing documents to the author's personal information before distributing PDF": PDF marking ciphertext. (Simply put, select the information to be permanently deleted, and then apply the deletion).
Here, taking Adobe Acrobat and PDFelement as examples, the specific operation of marking ciphertext is demonstrated:

Marking ciphertext is just one of the functions of these software solutions for securely distributing PDF documents, such as PDF creation and editing, PDF format conversion, form and signature, annotation and approval. Not to mention this. If you want to know more, you can download and play by yourself (do it yourself and have plenty of food and clothing).
Of course, these PDF editing suites have similar functions, and one is enough. Personally, I strongly recommend the two shown above. The reasons are: simple operation, beautiful interface, clear division of functions and easy to use.
