Redacting personal information from documents is a crucial step in ensuring compliance and protecting individuals’ privacy rights. In this blog post, we’ll explore how ComplyKEY Redaction, powered by, revolutionizes the process of redacting personal data on PDF documents with unparalleled efficiency and precision.

Understanding the Need to Redact Personal Information

Before delving into the redaction process, it’s essential to understand when and why redaction is necessary. Under regulations like the GDPR, individuals have the right to access their personal data. However, absolute transparency is not always possible, especially when personal data is intertwined with confidential information or when releasing certain details could harm the organization. Redaction becomes necessary in such cases to ensure compliance and protect sensitive information.

What Information do I Need to Redact?

The next step is figuring out what information should be redacted. This varies depending on the context and nature of the documents. It’s crucial to identify and remove any personal data that is not relevant to the individual making the request. Additionally, information about other individuals or confidential business details may also need to be redacted to maintain compliance and privacy.

The Data Protection Commissioner guidelines state

Redacting Documents and Records

Redaction is the process of concealing information while leaving intact the rest of the document or record containing it. This is commonly completed by ‘blocking out’ the material to be obscured but as will be discussed below, other approaches may be more appropriate, convenient or effective.

There are many situations in which it is necessary or advisable to limit the contents of documents or files that are to be published or otherwise disclosed. A document with uncontroversial contents might also contain confidential or proprietary information that should not be disclosed to the intended recipient or the public generally. Rules governing official secrecy, legal privilege or professional confidentiality can restrict disclosure of information either generally or to specific classes of person.

In the context of data protection, the most common situation in which redaction must be considered is when responding to a subject access request (or ‘SAR’) under Article 15 of the GDPR. (For more information on SARs, see the DPC’s web page and links here.)
