I have a customer who is asking if a technology or programming method exists

non-viewable. I know this technology exists for executable files, but I
didn't know if it can be done with a content only file. I have looked
(briefly) at DRM, but am not sure if that is the best solution since there
are cracking tools to circumvent the DRM and that we have no control over
the end client OS (Mac, Linux, etc.) and viewer software. We want them to be
able to view it during the allowed time period, then expire it. The content
files will be distributed to other hosting entities, so my client can't
control access to the files or how they will be streamed after the files are
created.
There is no 100% solution. DRM is the closest solution to what you are
after but there is nothing that's going to be perfect. In reality they
should revisit the reasoning behind the expiry and determine whether it
will be worth the effort.
