Let me preface this with the fact that I'm an intellectual property specialist. I bill $450/hour, and still have lots of time to work on my startup without having to take venture capital.
I thought about some educational answers for your questions, but the insult at the start of your comment rubs me wrong and I decided I don't owe you anything. So, I'll save them.
The first symptom of a new but incomplete understanding of patents is gold fever. That is when you have an idea that what you are holding is extremely valuable and that you must protect it from others at all costs. People tend to get irrational about it.
So here is some reality: The fact that you have even published your video (which is "use in commerce" under patent law) invalidates future patents that you might file on that same art. Then there is the prior art (including art you are not aware of), and the recent court finding in Alice v. CLS Bank that invalidates most process and method patents which describe software. These all work against the potential that your thesis is going to make you rich through patent licensing.
You can get a patent awarded, perhaps, that you can use to hoodwink an investor, but forcing an automotive company to pay you? Much less likely and it will cost $10 Million in attorney fees to get there.
Probably your school wants 51% of the revenue and your grant funding sources (and those of your college department) may have their own policies on patents.
Why bother with the QR code? The car has a unique identifier attached to the back bumper (as well as a globally unique one in the corner of the windshield). That can be looked-up to verify that the registration is valid, if need be.
I remember a british sitcom some time ago (perhaps it was one of the last seasons or reincarnations of Are You Being Served?) where some Londoners found themselves living in the British countryside and at one point the issue of tax discs came up. One of the locals just pointed out that they used a beer coaster. The local constabulary just took it on faith that everybody in the area was honest.
I've got a cubby in bookshelf in the dining nook (most convenient spot, cable-outlet-wise) with...
Apple AirPort Extreme AC
On my workbench I have a Raspberry Pi for experiments and AVR programming, and in the bedroom I've got another acting as a GPS NTP stratum 1 server.
I have a VPS offsite (obviously) doing e-mail, light web and shell duty.
