Hi all,

Funny this question should pop up today. I am currently working on
developing a standard approach for Database handled page(s) level security
(Document databases). I do consulting with customers that seek to implement
large document databases (in PDF) and all other kinds of uses once a file is
in PDF (Print On Demand, distributed viewing / printing, CD-R distribution,
mainframe to PDF conversions, Consolidating various separate customer
documents in a single package, etc...)

I will also visit Oracle this afternoon to see what their PDF integration
looks like... I'll keep the list posted. Informix has PDF handling with the
"DataBlade" option... I am to do some research on DBMS that handle PDF...

For now, let me briefly address your questions (signature at the end):

of a way to set a password for viewing a single page within in a PDF
document?

I plan to use a database with pointers to page(s), (i.e. doc_id, cust_id,
start_page, end_page). Access will be either from database first (list all
document pages for cust_id, then select from list) or from full text search,
then validate before serving the pages (from doc_id, page #, look-up in
database if current customer has right to view, then serve or not reply).

I am in the process of developping approaches that would enable "portable"
loading of this information in any database. I will check with my customer
and if it is OK, I will publish it publicly.

I have tought of various ways of doing it within the PDF itself but I
concluded that a Database will allways be needed anyway. Mind you, I plan to
develop a scheme that would (optionally) embed page identifications in the
PDF file so it could be processed by custom handlers.

I've been running it under Win95 for over a year now - no problems (don't
have long filenames though).

No idea.
