    What? If the document is accessible, and human readable, it’s parsable by OCR

      I don’t know what to tell you dude. A certified or digitally can’t/wont be read by OCR. A digitally signed document legally certifies that the document has not been modified. PDF editors such as Bluebeam or Adobe will not or cannot process a certified or digitally signed document.

      I’m not sure if that limitation is due to the process by which the document is certified or if it is a feature of software conforming for legality reasons. I’m not going to research this for OP, I’m just providing a simple and best accurate answer.

      Maybe current AI has better abilities to process document text? I’m not sure, maybe. But you’d think this would be a shared concern with groups wanting to protect documents for the same reason and therefore encryption would match.

      If it’s just the legality of it stopping a company from providing the feature, you would think most companies would want to keep out of legal hot water and would then disallow OCR processing. In this case sure there could be software that doesn’t conform, but for most application purposes I don’t think you’d have to worry too much.

        Many alternative OCR tools now simply screenshot the page. This is a cracked issue.

        Lots of software can manipulate PDF. Open PDF in libredraw change pages,print as PDF or export as PDF. A system that skims content is purposely going to bypass any signed restriction.

        Edit: Here’s how to bypass restriction in Paperless OCR.

        The parameter PAPERLESS_OCR_USER_ARGS: ‘{“invalidate_digital_signatures”: true}’ in the context of Paperless-ngx and OCRmyPDF allows OCR processing of PDF documents that have been digitally signed by intentionally invalidating those signatures. In its standard configuration, OCRmyPDF does not process documents with digital signatures so as not to compromise their integrity. Setting this parameter to true allows OCR on such documents
