Are digital-images & bitcoins as secret-keys a bridge to the visual mainstream?

[r1973]

Can BTC private-keys be safely hidden in public digital-images, thus to be used as secret-keys to BTC (0.13.1 core) wallets, assuming there is a way to program it?

If so, how? If not, why not? People are very visual-minded imo.

use QR codes maybe? https://en.wikipedia.org/wiki/QR_code
I don't know which wallets are offering this but it is a super easy process to make a QR code from any string (private keys for example). and then any phone with a camera can scan and turn that picture to that string.

but hidden? i don't know how can that be possible. what you can do is to encrypt the private keys and then make the QR code but you have to remember the password for encryption.

Yes, the question is how safely you need it.

is a picture with a hidden private key. The way its hidden makes made it possible to decode. The minecraft server needed is probably down now, but I think you get the idea.

is another one, solved.

is still not solved.

Thanks for sharing mate, i must have missed the first one but it looks like you gave it a good try.
I remember following the 2nd one for awhile and it was really interesting, out of my league to try and solve this stuff.
Never seen the 3rd so will check it out, cheers.

To be honest, I would not use Steganography to hide my private keys and store these image on any digital media. Most of what we do, are

being tracked and monitored. If you Google "Steganography" and start using it, you will automatically send out a clue to whomever is watching

that you are using Steganography to hide something. My private keys are generated "offline" and it stays "offline" until I want to use them.

Assuming all are being tracked and monitored, and BTC is an open-source, public to view, if you are for example traveling to other countries etc and want to have your bitcoin on reach anytime, can private keys be generated "offline/online" but stay "online" until you want to use them, while using steganography BTC function/app/feature, to hide your private keys and store these online among the billions of digital-images (files) already public on the web? Can this goal be open-source programmable, turning "naïve" images into secret wallets? Does it has any mathematical value?

From wilki: Image of a tree with a steganographically hidden image. The hidden image is revealed by removing all but the two least significant bits of each color component and a subsequent normalization. The hidden image is shown below.

Can the tree hide an QR code for a secret Bitcoin wallet?

the idea is great. I thought OP meant QR codes, but I was wrong. so the picture is made by our creativity. if someone wants to make one of the pictures, he can make it the way he wants.

well, I never heard a wallet offer such thing. probably people that make this thing just want to save their private keys they will not forget by using this way. but for wallet, I think it is enough to scan QR codes.
