Abstract
The system receives a call at a unique telephone number associated with a wireless telecommunication network and establishes a communication channel with a UE of a user. The system requests and receives a voice sample from the user and a PIN associated with the user. Using the voice sample and the PIN, the system performs a multi-factor authentication. Upon authenticating the user using the voice sample and the PIN, the system authorizes the user to make the modification to a blockchain. Upon failing to authenticate the user using the voice sample and the PIN, the system refuses to authorize the user to make the modification to the blockchain.
