What is Redaction?
It is the process of permanently blacking out or deleting sensitive or confidential information from documents.
Overview
Redaction is the censoring of confidential elements in a text, image, or database due to legal, institutional, or security requirements. Data such as ID numbers, medical records, or trade secrets are made unreadable using this method before being shared. In a true redaction process, the text layer underneath the removed information is also completely cleared from the file.
How it works
Artificial intelligence algorithms or rule-based systems automatically detect sensitive patterns within the document. The selected areas are both visually covered and physically deleted from the data layer in the background of the document. Thus, even if text is copied from the document, the confidential information cannot be accessed in any way.
Where it is used
It is used when sharing evidence files in lawsuits, anonymizing health records, and publishing publicly available reports.
Commonly confused with
It is often confused with simply drawing a black shape over the text; while the underlying text can be copied with superficial drawing, true redaction completely removes the data from the file.
Questions and answers
Is painting the text black on a PDF sufficient redaction?
No: If you only place a visual box, the underlying text can be copied; for secure processing, the text layer must be completely deleted.
How is artificial intelligence used in redaction processes?
It accelerates the redaction process by automatically recognizing and tagging sensitive personal data in documents.
