I would like to create a file that can only be opened for a small amount of time, say 1 day from the time it is first opened.
I would like to have a password on the file. I know how to do that. For example, I have a file that I send out on Feb 18, 2014 and is opened at 12:20 PM. I would like to set it so once it is opened, It can't be opened again after 1 day, or Feb 19, 2014 at 12:20 PM. Is this possible to set up?
You can restrict the use of a file with a DRM solution.
Good Day Bernd,
I am not a strong Acrobat user. What is a DRM solution?
DRM solutions are usually quite expensive, so I do not know whether they are applicable in your case. Adobe LifeCycle is one of them (http://www.adobe.com/manufacturing/resources/drm/). There are others. You can Google "Adobe PDF DRM" to find more.
