Hi List,
I have a friend, not in South Africa, who has a need to bundle raster &
vector data with a map viewer, so that the entire package can be
deployed via a DVD.
The catch is that usage of the data bundled with this DVD, needs to
expire after 12 months.
So, does anyone know of a QGIS based solution - even if it comes with a
proprietary encryption module that allows for an expiry date?
I'd be curious if anyone has implemented such solution.
I also think that there may be a possibility of fee for someone to
develop such capability.
Regards and thanks,
Zoltan
That's a pretty messed up product I wouldn't go anywhere near. But short
answer is this isn't a QGIS specific thing it's DRM which the Video Game
industry has plenty of solutions for, most of which are completely
circumventable by smart computer users.
Enjoy,
Alex
Largely my thoughts too - but I didn't think of steering him towards the
gaming industry.....
Just to narrow down the prejudice a bit, what about a situation where a
local authority is giving out a specific dataset that needs to be
current, or at least non-editable?
I expect one could watermark the datasets with a routine that the
source-code is not available for. This watermark could have multiple
date-stamps that would "help" in not being able to turn the computer
clock back - and the data encryption could render it useless for
anything except the viewer it came with - in QGIS case, the inclusion of
a hook to the binary subroutine that encrypted (ok, messed up :-) ) the
data.
Just a thought to stir up some discussion.
