Does a PDF Really Secure Your Data?

One of the most common types of documents you’ll find on the internet is a PDF. PDFs are popular because they can store text and images in a single file, which makes them easy to share and read. But what if you want to make sure that nobody can open or change your PDFs? It turns out that there are plenty of ways to secure your data with a PDF that goes beyond simply making sure it has an extension like .docx or .txt instead of .pdf.

Why is PDF Security Important

It is important to protect your PDFs because they contain sensitive information that you do not want others to see. If you are in a business setting and are sharing documents with clients or colleagues, it is important that these documents remain secure.

There are many benefits of securing your PDFs, including:

  • Preventing data loss and theft by keeping files safe from being shared without your knowledge.
  • Ensuring compliance with corporate policies and procedures that require employees to share only approved documents with other employees or clients.

Protecting PDFs with password protection

Password protection is a great way to secure your data. As per the Adobe Acrobat’s professionals, “By encrypting the file with a password, you can ensure that only those who know this password are able to open it.”

To do that, create a strong password using numbers, letters and punctuation marks. Also, make sure that the PDF is not too big or too small (for example, anything below 1MB should be fine). Then select “Encrypt” in the menu bar when you highlight it and add your password in its entirety.

Viewer protection with digital signatures and permissions

Digital signatures are a way to verify the authenticity of a document, even if they convert PDF. If you have digitally signed your PDF file, it will show as such when opened in Adobe Reader or Acrobat. You can also set limitations on who can view or use your document; this is called permissioning. If you set permissions to prevent people from printing or modifying the content in your PDFs, the software will warn users if they try to do so and not allow them to proceed without entering their passwords. 

A digital signature is an electronic equivalent of signing a piece of paper with ink, except it’s done electronically using encryption technology rather than physically with pen and paper—and it’s much more difficult for someone else to forge than scribbling on something.

Protection with certificates, watermarks, expirations, and removal actions

When you send a PDF to a recipient, how do you know that it won’t be altered? If they were to open your document and edit some text or add some images, can you tell? Well, maybe not. But there are a few ways that you can try to make sure your documents are safe: certificates and watermarks. Certificates protect the file by proving its authenticity. The certificate is used by users of Adobe Acrobat Reader 8 or higher in conjunction with digital signature technology, which allows companies like Adobe to sign all their products digitally so they can be verified as being authentic.

Yes, a PDF does protect your data. While there may be instances where a hacker can get past the security of a PDF, it is still one of the most secure file types available. As long as you keep your file intact and don’t share it with anyone else who doesn’t have access rights to view it, then there should be no problems at all!
