Handsignatures are totally ridiculous, I can't believe they have legal effect in the 21 century with a population that supposedly has an average IQ of 90.

I have always wondered that there is something wrong with signatures, even as a kid, when I saw my father sign checks. It seemed to me so easy to forge. But now as an adult it's literally mindboggling to me how ridiculous this idea is.

I just got home from my notary, we signed some contracts on one of my business dealings. She literally told me to sign the papers 2 times in order to make sure that it will not become forged.

I didn't want to be rude or to ask questions, she is a good person, I know her for a long time. But I could not grasp how she didn't realized the obvious nonsense of this.

Yes of course 1 copy stays in her archive, 1 at me, and 1 at the other party. However this still doesn't make sense from a logical standpoint.

I mean how hard it is to forge a hand signature? Just the one in the title picture? It's just CTRL+C, CTRL+V  .... Literally.

And I believe you don't even need a notary to create a legally binding contract, it is just optional. So if some guy signs a contract with another one, just 2 parties, that is also a legally binding contract, I believe. Like if you open a broker account or a bank account, you don't need a lawyer for that.

And even if you do it through a notary, it's not like there could be no malicious entity that would maliciously forge your handsignature and sign documents with it. This was literally happening in most of the corporate world throughout the 80's and 90's.

So it's totally ridiculous to have hand signatures that can be that easily falsified. It literally looks like this:

And then I am seeing Banks and other institutions using "touchscreen signatures", whereas instead of signing things on a paper, you sign it on a touchscreen.

It's totally ridiculous, and it just shows you the amount of disrespect these people have for your intellect. Let me sum it up for you:
<br/>
# BIOMETRIC DATA IS BULLSHIT, AND IT'S HORRIBLY INSECURE!
<br/>
This means: fingerprint, retina scan, hand signature, stamps, seals, DNA, "mother's maiden name" and other similar things are all bullshit, it can be easily guessed or faked. It provides 0 security, this really means 0 security, and it's exactly like the fence on the sidewalk in the picture above.

You are the one who is fooled by believing that these things make you more secure. And the banks and others horribly insult you when they make you use nonsense like these. So what is the alternative?

# [Public Key Cryptography](https://en.wikipedia.org/wiki/Public-key_cryptography)
<br/>
Yea. Actual intelligent people have invented Public Key Cryptography, that actually works, and it's actually unique to you, and nobody else can replicate it, given if the private keys are secured. This is how it should be done.

* You create a private key securely, and you don't give it out to anyone (hence remaining private)
* You derive a public key from the private key, which you do give out to the people you choose
* You sign a message with your private key, where the private key won't be exposed, and the output can't be reverse-engineered
* The other party then decrypts the output with the public key, and gets the message

This is how you can prove your identity. This is how Bitcoin works. Your Bitcoin public key (not the address but the `xpub` key) is exactly this, and a Bitcoin transaction is nothing more than just signing a message with a private key to prove ownership of the money.

So there is no reason why similar identity systems could not be implemented for people to have security. Biometrics is a huge scam. And you don't need to put a microchip inside your brain to prove your identity. You just need a pair of cryptographic keys.

Luckily there are easy to use GUI softwares for this:
* For Linux:  [Seahorse](https://wiki.gnome.org/Apps/Seahorse/)
* For Windows/Mac: [Kleopatra](https://www.gpg4win.org/)
