The site http://www.remoteapproach.com/ provides a "service" to track the usage of a PDF document. I haven't seen one of those PDFs myself, but rumours say it is implemented with embedded javascript. The Adobe javascript implementation allows many things users commonly don't expect. The implementation of javascript in PDF somehow reminds me of VBA macros in MS Office: - it is a powerful programming language - it is enabled by default - there is no sufficient security concept - there are ways to "auto-execute" code in a document (for example just by opening, closing, printing... a document) See http://partners.adobe.com/public/developer/en/pdf/PDFReference16.pdf and http://partners.adobe.com/public/developer/en/acrobat/sdk/pdf/javascript/Acr... for details. -- Michel Messerschmidt, lists@michel-messerschmidt.de
