The only way you can do this, is if the only service you use the provider for is storage. Encrypt the data before you send it to the provider and then they don’t know what they’re storing.

If they have to do any processing on it at all, then conceptually they need a plain text copy of it to feed into the CPU. And if they have that, there is nothing you can do to stop them from stealing it or using it.

There has been some research in this field, the concept is called homomorphic encryption. That is where you encrypt something in a way that allows a third party to manipulate the data without possessing a key. It is still very limited, and likely always will be due to the extreme difficulty of the question.

A stupid (as in, not intelligent) analogy.

Bomb laws don’t stop bombers. You CAN buy hardware store ingredients and make a bomb. Most people don’t do such things.

The point of the bomb law is so when they get a tip and raid someone’s house and find a few bricks of C4 wrapped in nails with a clock attached, they have something to arrest him for rather than saying ‘we have to wait until you use this to hurt people’.

But that’s also because that bomb has very few legitimate uses. There aren’t neighborhood bomb ranges where people go to compete and practice. You can’t use a bomb to hunt or protect yourself from 4-legged predators when in the woods. There aren’t bombing tournaments. You can’t use a bomb in self-defense or to protect your home or family. There ARE legitimate uses for bombs in mining, agriculture, industry, etc but those are uncommon and thus highly regulated.

A gun has many legitimate uses, and tens or hundreds of millions of law-abiding Americans use guns legally every day. Neighborhood gun ranges host classes, practice sessions, and competitions / tournaments. Guns are used for hunting and defense from predators in the woods. A gun can defend your home and family from intruders. And a small concealed pistol can be used to defend against street crime.

Simplistic logic that sounds nice but doesn’t actually work. There are more guns than people in this country. We have significantly bigger problems with illegal drug cartels than most. Drug gangs, who have access to illicit import capability, commit the lion’s share of gun violence. The right to keep in their arms is literally written into our Constitution.
Put those things together and you have a few very big problems.

The first is that any sort of gun ban will basically fail unless you amend the Constitution, which there is not political will to do by any means. And those who want to keep their gun rights will point out that there are at 4-5x as many defensive gun uses by law abiding gun owners as there are gun homicides. So it is unlikely that you will be able to get any sort of gun ban to happen.

Second, even if you did, you could never get rid of any significant number of them. There is no national registration scheme. A couple of states have their own registration schemes but those are generally not the states with the majority of firearms. Look at other countries that had similar situations like Australia, they have had numerous amnesty periods for people to turn in firearms and they still don’t think they have a significant majority of them collected.

Finally the question is who you are disarming? Remember, the lions share of gun murders are committed by drug gangs. A gang that can import illegal drugs can just as easily import illegal guns. Or, guns are actually not that hard to make, significantly easier than drugs. Any decently equipped machine shop can crank out guns, and unlike a drug lab which has to be out of the country the machine shop has a legitimate day shift use so it can operate in the open and pay taxes.
Point is, you will end up disarming the law abiding citizens while the criminals will still be armed, and willing to sell those guns to other criminals.

I also very much want to end school shootings. I hate that we are turning schools into fortresses or prisons. I hate the teachers, who are already paid shit, have to think things like ‘time to attack a gunman with scissors’.

But I want to spend effort and money on the policy that will most likely bring that goal about. Maximum bang for buck if you will. And I’m sorry but gun control isn’t it.
