Cryptocurrency is already fairly secure, thanks to the blockchain, but the Kairos Protocol aims to increase this security with facial recognition. Developed by facial recognition company Kairos, this new software employs biometrics as a means of verification to prevent cryptocurrency theft. The Kairos Protocol is currently available in alpha and aims to add a "know your client" (KYC) protocol to all cryptocurrency transactions and trades.
In addition to facial recognition, the Kairos Protocol can also verify a person through voice, fingerprint or iris scan. This method of security is meant to address middleman attacks and establishes a further layer of security as it's independent of the transaction system. Early adopters of the Kairos Protocol include security token distributor Securitize, as well as companies involved in crypto gambling.
