(2) Image file formats take up too much space. You must either verify or trust that a tool converting a document to a bitmap is not also helpfully preserving hidden metadata (like the author field, for example). (1) Most image file formats can contain hidden metadata (simple bitmaps don’t. Reasons why documents are not simply converted to an image file format are: More extreme methods involve printing to PDF, then OCRing the PDF to make a new document (PDF or otherwise), to ensure complete isolation from anything that is not visible. It is the conversion process itself which (apparently) ensures that non-visible material is excluded. In fact, an existing PDF would also be converted into another PDF too. The reason why is because a PDF printed in this way will not contain any hidden metadata which may exist in the original format. ![]() The print to PDF method is widely reccomended. I am currently examining digital redaction methods for use in government archives. Tags: Adobe, Microsoft, NSA, redaction, secrecy Using original source formats, such as MS Word, for downgrading can entail exceptional risks the lengthy and complicated procedures for mitigating such risks are outside the scope of this note.ĮDITED TO ADD (2/1): The NSA page for the redaction document, and other “Security Configuration Guides,” is here. This document does not address all the issues that can arise when distributing or downgrading original document formats such as MS Word or MS PowerPoint. Although the focus is on MS Word, the general guidance applies to other word processors and office tools, such as WordPerfect, PowerPoint, Excel, Star Office, etc. The complexity makes them potential vehicles for exposing information unintentionally, especially when downgrading or sanitizing classified materials. They can contain many kinds of information such as text, graphics, tables, images, meta-data, and more all mixed together. Thank you again for your reply, much appreciated.Both the Microsoft Word document format (MS Word) and Adobe Portable Document (PDF) are complex, sophisticated computer data formats. I am also well past my "sell by date" and not very competent on this dratted machine. I checked internet and it advises that painting even in black will allow recovery of the item on statement so I am at a loss what to do. ![]() I painted out some of the items but it is a messy and a time consuming process, I have checked in town and can find no stamp which will do this job for me. Have called Philippine Embassy in London and they cannot even understand why UK Manila need all this nonsense just for a holiday visa. I actually travelled to visit that country in October last year.on a UK passport only and no problem. They wish to know I can support my friends when in UK and I feel if I let them have the statement I should redact all incoming and outgoing lines and show a balance with the dates. The former I have scanned and "painted "copy across each one which does not look very professional but will still show, but the bank stament I feel is none of their business what is incoming and outgoing on my account. ![]() Friends from Philippines coming to UK for visit in July and UK embassy there requires from me copies of driving licence, passport and bank statement.
