Enhanced Security in Acrobat 9 and Reader 9

Sanjoy Ghosh describes the new Enhanced Security model in Acrobat 9

With the addition of interactive form features, multimedia, and scripting, PDFs can now download and send data over the Internet, which can create a potential security risk for both user privacy and document integrity. To address those security issues, Adobe® Acrobat® 9 and Adobe Reader® 9 feature an Enhanced Security mode designed to minimize those risks by providing control over cross-domain data access and how FDF files are handled. Because the Enhanced Security restrictions may affect some legacy PDF workflows, Acrobat 9 also provides ways to increase privileges for documents and servers that can be fully trusted.

The enhanced security in Acrobat 9 leverages an existing model already in use by Adobe Flash. By providing controls for who may receive data from whom, Adobe Flash can power rich Internet applications that are safe and extremely flexible. Many Flash developers, such as YouTube, use this model.

What this means to you

If you are adding multimedia to PDF files there are now ways for you to add these elements and have seemless playback. Flash files (SWF) and video (FLV and H.264) that are embedded in the PDF file or PDF Portfolio will play without a security dialog because the file and/or the Portfolio are considered a "domain". This opens the door to a lot of great new capabilities while allowing for even tighter security than we’ve been able to deliver in the past.

Over the next few weeks we’ll be finalizing the white papers for Acrobat 9 and I’ll be able to share more details on exactly what the Enhanced Security can do for you.
