Bottom line is, they have the ability with today's technology but I doubt they will ever put the effort forth to apply it.
I respectfully disagree, the app is still brand new, and we're only turning into more of a police state. I have trouble believing that they won't start using more digital technology to try to track hunting, illegal or not.
A lot of big cities already use gunshot sensors, and stuff like that becomes cheaper and more widely available, I would expect to see it out in the woods in popular hunting areas as well. Gunshot detected, all people nearby recorded to see if they've checked in game. That's like 15 lines of code, a microphone, and a camera or two. The microphone on your cell phone could be used to pick up the fine granular details too, All they would need to do is add in microphone access to the app, and I bet 99% of the users wouldn't even notice the new permission added.
Photographs are already searchable and geotaged unless you go out of your way to disable that feature. Any photo you take on your phone is then uploaded to a server (generally, unless specifically disabled) where that photo no longer belongs to you and can be thrown into a database and searched at will by someone else, like LE looking for photographs of things that have been killed, on phones that have not tagged in game. If you have an Android, go to the photos app and search for something like dog or car, it'll come up with all of the pictures of dogs and cars in your library, it already knows what's what.
The state is covered with license plate scanners, they know where you are regardless of whether you have your phone or not too. As artificial intelligence gets better they'll be able to track suspicious driving patterns and cross-reference them with hunting apps.
People will cheat if that's what their intentions are irregardless of what process is in place.
I totally agree with that, but it's only going to get harder and harder as they use digital technology to track everyone.
I think it really just comes down to if TWRA is going to put in the effort. As the technology becomes cheaper and easier to use, less effort is required to use it, and we're more likely to see it used on a wide scale.
