if yoi tell me your birthday how can i forget it?
if you borrow me a car i have something i can return...
That's not really relevant. GDPR doesn't ask people to forget things out of their minds.
So let's rephrase to a more relevant example:
> if yoi provide me your birthday on a web form and I put it in a database how can i forget it?
This now becomes relevant, and easy do answer. You delete it.
Ask any husband.
Joking aside, if the memory is on a computer system, as opposed to a person, you can, you know, just delete it.
Obviously, removing the commit would break git's ability to sign any hashes for that repository after that point…
And thinking it through a bit more, what about the companies that use v8? Could I ask my regulator to get Joyent to remove it from their systems? I'm sure they have copies…
You entirely missed the point of my hypothetical, which was about immutable data structures like git employs.
As it turns out, our business also uses a git-like hash-chained commit log for our normal database. Deleting old entries would thus violate the integrity of our database. Is that now illegal under the GDPR?
Law has nuance and cases (and corner cases), it's not some strict predicate.
- personal data (car) are any data that have potential identifying a person
- person owns its data (car). You cant buy them (well this part is different than the car), you cant steal them, you cant sell them, but you can borrow them from. But for that you need to ask (consent), where it is not allowed to trick the owner to give them to you, whithout beeing fully aware what was borrowed and why. And if you are borrowing the data for someone else, you need to ask about that too. And tell when you will return it.
- it is immature and unfair to play grumpy if someone doesn't want to allow to use its data. Or try to force/blackmail them from him. So its not allowed to do that (noyb.eu)
- once you borrow the data (like property, envision a car), behave acordingly, owner can demand them back, demand to see them, demand to know what you are doing with them and if stolen it is completely normal to tell them about that. And if they were stolen due to your fault (leaving keys in a car), they might demand to be compensated. Same goes if you misuse them (let me put some fertiliziers on back seat, forget to return them, giving it to all your friends without asking,...)
- if the data owner asks you to do something that requires his data ("hey, can you please take my car and bring me icecream from the store") you don't need to ask for data, it is expected you can have them.
Did I forget something? I consider it simple, as long as you try to stay genuinly respecting to other persons ownership. Just think about borrowing your car or borrowing car from your best friend and you wont go far wrong.
