LiveCycle security
LiveCycle security: Dan Shea of PlanetPDF continues a security series on the new Adobe Acrobat family, this time focusing on serverside authentication of reader privileges. (Static documents and brochures may not need much security, but annotations and forms may require high security -- many different user needs now.) In prior versions of PDF files security permissions were held locally, and a non-Adobe client could bypass them -- similar to how the "don't import" bit in a SWF file means the Macromedia tool wouldn't open the deliverable, but other apps might. Now the info in the document can be strongly encrypted, with the key held safely behind your firewall, requiring a valid transaction with your server to read a secured document. This is the fourth article in Dan's series on PDF security, and there's a related overview from John Bringardner at PDFZone.com this week too.
