Links
There is not much information available on tracking PDFs on the web. I've compiled a small bookmark list:
- Remote Approach, the commercial alternative
- Are your PDFs spying on you?, article at pdfzone.com
- Slashdot article
- Unexpected features in Acrobat 7, article at LWN.net
- Acrobat JavaScript Scripting Guide by Adobe
- Acrobat JavaScript Scripting Reference by Adobe
There is at least one more commercial company in the business of PDF tracking, but unluckily I lost the link. If someone knows it, please mail me.
