DocuVieware Redaction

What is Redaction?

The word redaction comes from the legal domain and was first applied on physical documents, usually by blacking out portions of text in permanent ink, so the text underneath is not readable any longer.

Applied to electronic documents, and especially PDFs, redaction is the process of permanently removing visible text and graphics.

Not to be mistaken by black rectangle annotations, the redacted text or image cannot be retrieved once the redaction mark is burned into the document.

Why is Redaction necessary?

Many industries have a legal obligation to keep their data private, such as the Legal domain with judicial secrecy, the Healthcare sector with medical and professional confidentiality, and the Financial system, just to name a few.
But even for all other businesses or organizations, regulations exist at several levels to protect employees and customers:

  • GDPR in Europe
  • CNIL in France
  • California Consumer Privacy Act
  • Brazilian Landmark Privacy Law
  • and more to come.

Redaction is only the first step

Removing the visible data of an electronic document is sometimes not enough.
Sensitive information can also appear in other places, such as:

  • metadata (author, title, creation date, etc.)
  • annotations
  • comments
  • hidden text layers (under annotations, for example)

Other sensitive points to check are:

  • images of different formats
  • spreadsheets
  • attachments
  • indexes

To secure your documents with DocuVieware, you can also add a digital signature and passwords with permissions, and convert to PDF/A.
