Given the incredible capabilities of the modern digital world, the methods that pose a threat to the preservation of information are growing daily. Therefore, its protection is extremely crucial. Regardless of whether it is a confidential contract, a financial report, or just personal data, it is essential to take all possible measurеs for document protection. Portable Document Format is one of the most widely used formats for exchanging important documents. Therefore, PDF files, like any other format, need to be properly protected.
PDF Encryption
This is one of the most effective ways to protect PDF files.
Encryption converts your data into a form that cannot be read without the apрropriate password or key. This ensures that only authorized users can access the file content.
How to encrypt a PDF
Encryption of this format can be performed using various software tools. In particular, PDF-XChange Editor, Adobe Acrobat, and others. The main steps to encrypt a PDF are as follows.
- Open the file in a PDF viewer.
- Select the encryption option. For example, in Adobe Acrobat, this can be the Protect with password option.
- Enter the password.
- Confirm it.
- Save the file.
These simple steps will help you make your PDF secure from unauthorized access.
Sometimes you may need to edit PDFs before distributing them. This may be, for example, to erase sensitive information (personal data or credit card numbers). For this, there is a function to redact a PDF. The editing process can include PDF black out text or removing sensitive data in the preview program, i.e. redact in preview. To do this, open the desired file in a PDF program and select the editing tool. Then follow the necessary steps and save your changes. If you’re having trouble, there are web-based resources that can offer step-by-step instructions and tips on the process, so you can ensure an extra layer of privacy before sharing the document with others.
Restricting Access to Editing
Another important factor in document protection is the ability to lock PDF from editing. With this lock, you can avoid unauthorized changes to the file. Such unauthorized changes can be critical for official documents and reports.
Lock a PDF from editing
You can use Adobe Acrobat to lock a PDF from editing. To do this, do the following.
- Open the file in a program that works with this format.
- Select the protection option.
- Set editing restrictions.
- You can set a password to restrict editing.
- Save the file.
This will make it possible to view the document, but will prevent anyone from editing it without permission.
Signing and Locking PDFs
Another important aspect of file security is the signing of PDFs and the ability to lock PDF after signing. This is an extremely important feature for:
- legal documents,
- contracts,
- other official documents where it is critical to preserve the integrity of the signed document.
- Open the PDF in a program that works with this format.
- Add a digital signature.
- Lock the document after signing- This can be done through the signature settings by selecting the option to lock the document after signing.
- Save the document.
These steps will ensure that the document cannot be changed after signing without detecting fraud.
