| Aug 21, 2018 at 9:44 | comment | added | Yooooomi | My vision is more to encrypt data from a certain key, then allow or deny addresses from getting the key from the blockchain to decrypt this data | |
| Aug 21, 2018 at 9:42 | comment | added | Henk | In this case, you could just not encrypt and publish the data using the deleted viewer's public key after an update. | |
| Aug 21, 2018 at 9:40 | comment | added | Yooooomi | Everyone can copy data, everyone can screenshot or whatever, this is not the issue here :) | |
| Aug 21, 2018 at 9:39 | comment | added | Henk | How would you handle the viewer copying the data before deleting them? | |
| Aug 21, 2018 at 9:38 | comment | added | Yooooomi | The thing is I that I want to be able to dynamically manage permission to this key since the owner can add viewer and remove them on the go | |
| Aug 21, 2018 at 9:35 | comment | added | Henk | You could use asymmetric encryption. I won't go into detail, but you could have the sender of the data encrypt it using the public key of the receiver, and store it either on the blockchain, or on IPFS or something, in which case you could store the data hash on the chain for verification. The public key is not the same as the address. It must either be provided by the receiver, or by deriving it from a signature of the receiver. There are ways to do that. After the data is stored on IPFS, the receiver can decrypt the data using their own private key. | |
