Is it possible to reveal the bitcoin barcode address through human appearance?
For example, the owner of the wallet address will create a barcode with his own appearance/face.

Please check the example of face barcode

I think there are applications and websites that can help you covert anything to any form of bar code that you want, but making your address appear in a human face, especially the face of the wallet owner, makes no sense to me.
 
Like, where is the privacy? Or you don't use bitcoin as a means to hide your identity. Doing that typically means telling people, Hey man, this is my address, and whatever is in there are all my holdings, which they can use to trace who you are in real life.
 
If the person is not worried about government traits, how about his own seclusion and security? Doing that with a large amount of bitcoin at such an address can make you a target for fraud and theft, who will start stocking every bit of your movement until they rob you of those holdings.
 
Our bitcoin holdings should be kept private, and doing so is not private; anyone can easily identify who is behind that barcode, unless you are never going to make that barcode public; if not, it's not safe at all, IMO.

If the face can be interpreted as a barcode then this barcode can surely be turned in a bitcoin wallet address.
By using a brain wallet generator you can turn any aphaneumeric string to a bitcoin wallet address. An open source and audited project must be used do do that though otherwise other issues could be introduced.

But even if we assume that some facial ID device is always to print out the same barcodes for each face... How about if someone else scans your face from a picture and gets your private key?
This is a very fundamental issue with this. If your private key is your face then you have a useless address because anyone that has even captured your face would have access to your funds. Address generation is meant to be based on private data.

I never heard that there is a face share barcode but on a QR code you can turn your BTC address into a QR code and put your image in the middle of the QR code this is possible but making your BTC address into a barcode face of yours I don't think it's possible I don't see any software yet that can do that.

Even the facial recognition that generates a Bitcoin wallet with your face I never heard someone develop it.

No, it's not possible to generate a Bitcoin address using a face share barcode. Bitcoin addresses are made up of a series of letters and numbers, and they can only be generated using special software. A face share barcode is simply a visual representation of information, and it cannot be used to generate a valid Bitcoin address. It's worth noting that some services may allow you to generate a Bitcoin address using a QR code, which is similar to a barcode but uses a different type of technology. However, a QR code does not use a person's face or other identifying information.


I think what you're asking about is something called "biometric identification" or "biometric authentication". This is a type of technology that uses physical characteristics, such as a person's face or fingerprint, to verify their identity. While this technology is often used for security purposes, it is not used to generate Bitcoin addresses. The reason for this is that Bitcoin addresses are designed to be anonymous, and using biometric identification would go against this design. Additionally, there are potential security risks associated with using biometric identification, as it could be possible for someone to steal or fake a person's physical characteristics.

I don't know how these barcodes are created, but if they can be crafted to decode as arbitrary data, then it should be no problem to take any image, including your own photo, and turn it into a barcode that scans as an address.

But if you want to use facial recognition to derive an address from your face id, then it won't work, because an address is derived from a private key, not from some other data, and if you derive your private key from your face, than anyone who sees you will be able to steal the coins from that address.

It's one of most terrible ideas I have ever known from Bitcoin users.

Satoshi Nakamoto creates Bitcoin for privacy, anonymity and everyone can get privacy and anonymity if they use bitcoins with good practice. On top of that, you have the idea to use your face/ appearance as where you store encrypted bar code for your Bitcoin public address. Everyone will know you are the owner of that address, IRS will find you and  you can be kidnapped or killed by criminals too.

If you use faces, photos of other people, it is immoral.

you could do the face of an enemy.

along with a few numbers under it.

I'm not sure if this is what the OP wants, but I really don't think it's necessary. A few little tricks in photoshop is how I got this image.
But actually listening to the OP's proposed idea, I can only think about the meme, maybe you're talking about something more terrible that I haven't figured out how to use yet, but I wonder what its application is here?

In the form of the picture you gave I think is possible but in the form of the real human face, I dont think is gonna possible to reveal an address. But it is possible if you create an app that detects the face person and add a Bitcoin address to it, but it only works on your app. So basically just put face and address on the same database.

Even if this was possible it’s not a good idea. The Face ID is not as secure as you think, it’s more secure than the fingerprint id but there are reports about siblings being able to unlock phones because they share similar features.

Due to these issues you can tell why it would be problematic. Another issue is that if some hacker finds out you got tons of bitcoins, they can simply hold their phone in front of your face and they might be able to gain access, it’s not a good idea.

Yes it is possible because it is happening right now, few days ago I watched a video of Indian Youtuber who used to troll funny videos and also give reactions to new technologies, I think the name is tamny something like that. Well, in that video his companion share that people are creating bar codes with creative designs like symmetric designs.

Well, if those bar codes with such designs can work then a human face can be designs in bar codes too. Because bar code consists of black and white dots that are captured by the reader and then translated to understand the meaning.

Which mean a code is being decoded, but talking about BTC address, I think it can be made but it might require technical skills and we might have to hire professionals to do the work.

If the biometric data can be converted into bytes of entropy, yes, it can be done. Because once you have the entropy you can simply generate the private key and address as usual.

However, there are two problems with this. First, this will only make one key because people's facial data generally don't change without plastic surgery and other extreme stuff. Second, the algorithm has to make sure that there aren't random variations in the entropy which would result in the private key getting lost (by means of a different one being created instead).

The technology isn't as good as that. Only Apple can do that with their FaceID methodology IF I am not wrong as it's the most secure and most efficient system I have ever seen in facial recognition in the history of mankind. Some other Japanese companies are also working on Face recognition for traffic tickets if you cross a red light or speed, those cameras will recognize the face instead of the car plate as anyone can drive anyone's car. And China I think has already implemented something like this already, I saw a video on TikTOk.

first of all trying to "vanity gen" a private key number that corresponds to a public key that looks like you in a barcode is a magnitude of degrees more difficult then finding a grain of gold on a sandy beach, using your tongue

so forget using it for a public address concept.
many people then think about using your real face as access to a wallet which uses your face as your private key/seed, however this has problems too

there is tech that can scan your face to turn into datapoints.. and those datapoints can be an ID
facial recognition systems do exist

the disadvantages though
1. a hacker can show a picture of you to a camera and gain same access
2. if you have a stroke, scar your face, age.. you can lose access to your ID

facial ID does work great in high secure work places, that update your record of your faces datapoints to remain valid.. where you have the convenience of not having to tap an access card at each door.. but it only works great because when you got employed you went through security department to use some other ID/managers authority and a picture of your face to initiate validation to register you..later as you age,  each time you pass the camera the system updates a latest pic datapoint(which changes) to your record to smoothly reregister the changes to your face as you age, but retain access to your workplace.
if however you have medical issues(stroke, palsy) or accidents(scars, burns). you can return to the security department, use other id/managers witness authority to update/change the datapoint to reregister your access to the building using a more significant change to your face..
however just relying on some software that just turns face into data points. where your datapoints need to be the same.. where value relies on them data points forever(same key/seed)..... as your face changes. you lose access

yes when you first register your face it produces a data point to produce a privatekey/seed. which you should backup the privatekey/seed separately as the words/datapoint..
then when your face changes you have te words as a secondary method to access when the face scan convenience ends

No smartphone maker's facial recognition technology is perfect, that's why there are so many videos out there that show people unlocking other people's phones using photos, masks, and so on.

Everyone's largely pivoted to using fingerprint scanning (no longer possible on iOS, now that the Home Button is gone).

fingerprint scanning on phones use less datapoints. so less secure
malicious people can too (research fingerprint forensics) can copy a fingerprint from things you touch
only advantage are they cant just get your fingerprint from your facebook remotely, they will have to physically stalk you first and take items you touch

Thank you .

I think it will better to create face code with any popular person or celebrity from any angle but wallet owner face is not good for btc.

Thank you , I think any popular person face will be good from more and different side and angle But not real face.

What about famous people and celebrity face from different angle?

What's the point of doing this anyway?

P.S. You don't need to reply to each comment in a separate post. By doing so, you are violating point 32 of the forum rules (https://bitcointalk.org/index.php?topic=703657.0). If you want to comment and there are no posts from other users after your post, just add your comment to your old post.

Hopefully it will never be impossible or anything like that. Especially with all sorts of CBDC. Otherwise it will be the end. For freedom and Privacy.

Again, this would open up ample opportunities for fraud. With AI and deep fake appearance generation, it would be possible to gain access to almost any wallet. I wouldn't want that at all.

Since a third party can scan your facial data, which is supposed to be unchanged, and generate the private key from it, you are not safe, especially if someone knows that you generated a Bitcoin address from your facial details. generating a Bitcoin address randomly and with an entropy higher than 128 is what could be called a secure bitcoin address.



It is possible, but it will be more likely that one or two bits will be incorrectly decoded, which means you will generate a different private key and therefore a different address.

I want to repeat like other users' statements that the use of the face for barcode is not a good idea.
The use of fingerprints on smartphones with the aim of getting multiple security when someone tries to open our smartphone is also not so safe. As in a film disclosure of secret mission, it is still possible to copy our fingerprints with various experiments including imitating it when we hold something without using gloves.

I haven't heard of face QR codes before, but I've looked around the Internet, and it seems that there are some apps that allow doing that. To be honest, like many people here, I really don't get it. What's the point of using a human face for a QR code? It sounds creepy and problematic to me. But aside from that, I wouldn't trust those apps with something as important as BTC address code.
Frankly speaking, I don't trust QR codes for BTC in general, as there are many scams related to them, and I feel more comfortable seeing the address and double-checking whether I got it right when copying and pasting it.
