What is PDF redaction and why does it matter?

PDF redaction refers to permanently deleting or covering sensitive data in a PDF document. Redaction is a proper removal of information, as opposed to just hiding information by black box, where it is simply deleted and cannot be recovered. PDF redaction matters because:

1. Laws avoid identity theft: Social security numbers, addresses and bank account information are personal data that must be guarded to avert identity theft.
2. Confidentiality: When sharing sensitive information in a legal or business setting, it is possible to share information without removing it and share sensitive information, which can cause reputational or financial damage.
3. Secrecy of trade secrets: Reduction of business plans, agreements and other proprietary information is important to ensure that the competitors do not get access to confidential information.

How to redact a PDF document

In order to be able to redact a PDF in a safe and powerful way, it is necessary to use the following steps:

1. Choose the right tool

The first step is the choice of the appropriate PDF redaction program. One must have a tool that offers permanent redaction rather than a visual covering-up. One of such tools is the PDF redaction tool that provides a secure redaction by entirely eliminating sensitive information from the document.

2. Open the PDF document

You will need to open the document with the tool of redaction that you have chosen. The majority of PDF redaction tools provide an easy way to upload and read the document and start redaction.

3. Select the content to redact

With the help of the redaction tool, underline the text or sections of the document with sensitive data. This may be the personal identification numbers, classified business information or any other personal information. There are also tools that enable you to find a certain text, like names or numbers, and this makes it more effective.

4. Apply the redaction

After you have marked out the sensitive material, use the redaction. This will delete the chosen text or data, and a black box (or other cover, based on the tool) will take its place. Make sure that the data is completely lost and is not recoverable.

5. Save the document

Put aside the document as a new file after redacting it. You should have the original unedited copy of the information for record purposes and have a copy of the redacted version of the information shared or distributed.

6. Remove hidden data

Still, even in the case of visible redactions, hidden information might be stored in the file, including metadata, comments, or revision history. Auto-removal of these elements may be done by some redaction tools, but it is always wise to scrub the document of any concealed message before completing it.

Top things to remember when redacting PDFs

1. Only overlaying text. The simple act of covering some sensitive information with a black box is not enough. With the help of the appropriate software, the text can be frequently restored. Always apply an appropriate redaction tool that would make sure that the content is permanently removed.
2. Ignoring hidden data: The metadata and hidden comments can also have sensitive information. It is important to make sure to look for and delete this hidden data before posting the document.
3. Redacting a single version of the document: In the event of a document having several versions, make sure that all the versions are duly redacted. An unredacted copy can be shared erroneously.
4. Not testing redactions: Once the information is redacted, one should ensure that the information cannot be retrieved. A few of the tools also provide a test feature to attempt to unredact the text to ensure that redactions are permanent.

3. Establish a redaction policy: In case you are employed in an enterprise, come up with a redaction policy that guarantees the uniformity and safeguarding of documents among departments.
4. Securely store redacted documents: Once a document has been redacted, an encrypted file-sharing solution should be used to ensure there is no unauthorized access to it.
5. Double-check redactions: One should always go through the redacted PDF and then share it. Search in places where one might have missed or forgotten to look.
