Comic Strips is a community for those who love comic stories.
The rules are simple:
- The post can be a single image, an image gallery, or a link to a specific comic hosted on another site (the author's website, for instance).
- The comic must be a complete story.
- If it is an external link, it must be to a specific story, not to the root of the site.
- You may post comics from others or your own.
- If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
- The comic can be in any language, but if it's not in English, OP must include an English translation in the post's 'body' field (note: you don't need to select a specific language when posting a comic).
- Politeness.
- AI-generated comics aren't allowed.
- Adult content is not allowed. This community aims to be fun for people of all ages.

Here is my idea: Everyone makes a private key. When they buy a song they receive the file and a digital signature by the label saying they sold it to your ~~private~~public key. When you are caught with a bunch of songs, you have to prove ownership using your key. Tadaa provable ownership, no blockchain, You loose the file, but still have the signature? You can download it again and all is good.
EDIT: Of course, they would sign the public key, sorry.
A digital signature from the label would be created with their private key.
What would they be signing? Your public key plus the ID of the song? They can't sign your private key, it's private.
What stops you sharing your private key and a song with a friend. Then when either of you need to provide proof, you can both show that you have the private key that matches the signed file?
Well they would sign my public key plus ID of the song. I can prove, it is my public key and everyone can verify the song belongs to me.
You are right, to ensure noone can "share login" so to say, it needs to be tied to you personally. That would deny privacy sadly.
EDIT: Didn't notice I wrote the wrong thing, thanks for notifying me.
Wait, isn't that just nfts?
I don't think so. There nothing non fungible in my idea and nfts require a blockchain.
But what if you still have file, but lose the signature?
In this construct the key is the thing, that signifies the owner. If it's lost, there is no help. Unless the key is tied to you and an authority can vouch for you.
Well if the record label was still around they could make ownership details public, or let you download the signed file again.
How would they know the copy legally belongs to you if you lose the key? Would they require some form of ID on top of that?
