To make sure you caught all the information that needs to be redacted, you may want to ask a trusted individual to verify that you did not miss any information. Sometimes, having another set of eyes on the document can also help to catch any information that you may have missed. Let the reviewer know what method you used to redact the information so they can test it properly. If you are dealing with very sensitive information that could have legal implications, you may want to consider using a redaction expert. These individuals are trained to do redactions and can verify the document for you to ensure it contains no errors or mistakes. To confirm the redaction was done properly, you can do a simple test on the final, redacted PDF.  Select text several lines above your redacted area and ending one to two lines below it. Paste the content into a word processing document or in Notepad. Check to see if the redacted text is not present in the content. If it is not present, the redaction has been a success.
