I have often thought that volunteers allowing their computers to be used to search for intelligent life in images, much as a lot of people do, or did, with the SETI project, would be a good idea.
Except for the wee bit about trusting those who would run such a program with access to their computers... and that we might find ourselves wanting to use steganography one day...
I suppose I can assume at this point that there are dedicated computers out there, steadily crunching every image on the web to see what may be hiding in them.
Surprisingly, a lot of stego programs, or users, do not encrypt first.
re: now the tsa will be watching... I thought they already were, compliments of backscatter technology, except for when a 2-D image just isn’t enough.
Now they're really gonna be motivated..............
