We have a client who has a unique need and we thought this would be the best place to engage an expert. Here is what the client wants to do (programmatically):
1) He wants his clients to be able to download encoded pdf files (possibly with embedded media) from a web site.
2) These files shall be password protected. (Not a big problem.)
3) The passwords on these files should be unique in each instance and should be generated on the fly based on the username of the client at the time of download....
(I don't think we have a big problem, thus far. Now, here is where things start getting a bit tricky.)
4) He wants to control the number of times the pdf file can be opened AFTER it has been downloaded. (Set by a toggle in the script controlled server-side.)
5) He also wants to limit the number of times the file can be printed based on permissions given at the time of file creation.
6) In certain instances he would want the file to be incapable of opening after a certain duration or beyond a certain date.
7) Files cannot be 'Saved As' any other format or file other than the native download.
8) The file should not be readable on any computer other than the first one onto which it was downloaded.
Any takers? You may e-mail me: emeka [at] digital-threshold [dot] com for clarification....
Adobe has such an application, and it's very (very) expensive.
