Of course, PDF is not the answer to all documents, or even most. It's time to stop thinking of documents as paper, and start thinking about them as PDF files! It's an ironic testament to the success of PDF in representing paper documents in a digital context. When they make this mistake, these users are confusing the color of the highlight for the functionality they'd expect from paper. Some users even legal professionals using desktop computers for 20 years or more, even those who have always used digital documents, sometimes fail to understand the difference between highlighting and redacting. We see this in the prototypical error users make when redacting digital documents – the use of a highlighter tool, which only changes background color, and doesn't actually result in redaction. it's hard not to notice that end users' ideas about redaction remain stapled firmly to the age of paper. The proliferation of websites emails, posts, documents and other content bearing (potentially) personally identifiable information (PII) and other sensitive material, from court records to medical information to trade secrets, Freedom of Information Act (FOIA) requests and government investigations, makes redaction a critical capability in managing digital content.Ī Technical and Cultural Assessment of the Mueller Report PDFĮven with OCR, the Mueller Report PDF isn't fully searchableįurther, in an era where document distribution no longer requires physical paper when it's possible to transfer millions of pages in seconds, and search them in even less time.
To be useful, redaction must leave un-redacted content fully intact, but it must also account for the fact that a redaction has occurred, typically by introducing a colored box in place of the redacted content. Redaction differs from editing, which is key to understanding why redacting PDF differs from simply deleting text. The need for redaction as a feature, however, exploded. Once people were able to share documents without using paper the physical tools became obsolete. Preview fits a lot of great simple annotations, I was surprised it didn't have this built in.Historically, the process of redaction - removing content from documents for national security, intellectual property, privacy or other reasons – has involved physical implements such as razors, grease-paint, magic-markers and photocopiers. In my case, I downloaded it and used it for blurring of text since I know I'll be using it for other capabilities in the future. Select the area you want to blur first and then use the appropriate blur filter.Īgain, I know it's not as simple and direct as some of the other tools, but GIMP just offers a lot of other features built pretty well. If you want to be cleaner, you can use the rectangle selection tool first and then use blur so you get sharper edges.Ģ) There is also an option in the toolbar to blur selection as well (so it's more evenly blurred) - I would recommend a high (15x15) gaussian blur ( Filters -> Blur -> Gaussian Blur. I ended up just downloading and using GIMP because of it's flexibility as a tool.ġ) Simply use the blur tool and drag over the text. I was looking for a quick solution using the preview tool as well and blocking out or cutting text won't work (since I need to give the notion that text goes there).
