The G-KNOT wallet has adopted
a FINGER VEIN AUTHENTICATION method
in order to provide a more advanced decentralized
crypto wallet that is free of hacks or loss.

Finger Vein is a Private Key

With G-KNOT wallet, there is no need to use Mnemonic Phrase, PIN number or fingerprint. User’s finger vein acts as a private key, which has little risk of loss, forgery, theft, duplication or hacking. When transferring cryptocurrencies to others, users use their finger vein instead of PIN number or fingerprints.

How to Create Private Keys

Private keys are created and managed by user’s finger vein. Since hemoglobin in the blood absorbs near-infrared lights, vein patterns appear as a series of dark lines. The finger vein device captures an image of the finger vein patterns. The captured image is then converted into data. The data are encrypted and stored as a Biokey, which is double encrypted to create private keys (how to create private keys with Biokeys cannot be specified). Public keys are generated from the private keys. The public keys are stored in the wallet, but the private keys are not, for a security reason.

How to Sign a Transaction

The user can recover the private key with their finger vein at the time he needs to sign a transaction. The user puts his finger vein on the finger vein device and creates a new Biokey. The newly made Biokey is compared against the stored Biokey. If both are identical, then it instantly generates the private key to sign a transaction. The private key disappears right after signing a transaction. Private keys are not stored anywhere. Users use their finger vein instead of private keys when signing transactions.
