From a legal standpoint, you'll recall that a fast approach is available. The approach is set out in section 163.1 of the Criminal Code, which deals with child pornography. I think that you could consider an equivalent provision for the non-consensual distribution of intimate images. You could build on these powers, which allow for the quick removal of illegal content.
That said, you need funding to create teams dedicated to this issue. I know that it's hard to say that one case is more serious than another. However, the police forces that are already dealing with child pornography cases would be prioritized. What happens when images of an older person are involved? I think that you should also look at creating police units or hybrid units, whose mandate would be to address this issue using the proper legal tools.
Regarding the digital footprint, certain technologies already make it possible to recognize what's happening in a video. We've moved beyond mathematical calculations and hashing to find the digital footprint. Software is now available that can help us do this quite well. In my opinion, everyone should check the illegal content database before allowing content to be distributed.
