[Sigia-l] Delivering documents for viewing only (no printing, no saving)

[Dave]

All True Ziya,

And like you said it is about effort/cost/success.

Some of these products though require windows to run and thus can't be
used on non-windows systems so that point b/c moot.

David, the Extranet piece is only relevant if you mean that the end
user isn't allowed or shouldnt have to install any new software, and
needs to be completely OS/browser independent.

Since most solutions are about encrypting and decrypting the
information, if you use the wrong system, it can't decrypt and won't
be visible. These encryption applications need to be installed, though
many are plug-ins for PDF or MS Office.

Oh! something I have seen one company do is convert everything to TIFF
and then have the user install a TIFF viewer as a plug-in. A bit harsh
indeed. No temp files, the TIFFs get loaded into memory.

Good luck!
