    I have a PDF on my site that contains a lot of duplicate content copies from other sites. I want google to not be able to read this PDF.
    I have tried converting it to an image based file, so the text is not searchable. But, I think google has OCR capability and they still indexed the content.
    Is there anything I can do so google cannot read and index the PDF?

    I don't think you'll be able to stop them. Maybe via robots.txt, or .htaccess ...
