Secure PDFs from Unauthorized Access

Hi there,

 

These days, smart devices contain lots of sensitive information such as private documents or personal finance information. Whether you’re working for a business or are a student, the following tips can help protect your PDF documents at all stages of the workflow to ensure that data doesn’t fall into the wrong hands.

 

Watermark Your PDFs

 

Organizations usually watermark documents with identifying information (e.g. company and username) to prevent individuals from leaking documents and to help identify the source of the copy.

  1. Select and open the PDF document
  2. Tap the “Kdan Cloud” button and choose “Add Watermark” from the service menu
  3. Tap either “Text” or “Image” to insert a watermark into the PDF
  4. Move the watermark to the desired position
  5. You can customize the watermark by tapping “Settings”

(Note: Different watermarks can be added to a single file, and every page can have multiple watermarks)

Encrypt Your PDFs

 

If the document is secured with a password, only the intended recipient in possession of the correct password will be able to open it.

  1. Go to the file list and tap the “Edit” button on the top right corner
  2. Select the target file and tap the “Encrypt” button
  3. Then enter a new password to secure the PDF

  2. Find out the target file and tap “Share File Link”
  3. Choose “Password Protected” from the pop-up window
  4. Then enter one password to secure the download link
