Mutually authenticated voice communications

A non-transitory computer-readable storage medium storing a plurality of instructions executable by one or more processors, the plurality of instructions when executed by the one or more processors cause the one or more processors to:

• create by a user device a first communication channel with a backend;
• create by the user device a secure session across a second communication channel with the backend;
• receive by the user device a first identification message from the backend via the second communication channel;
• receive by the user device a second identification message from the backend via the first communication channel;
• send by the user device an attestation that the second identification message matches the first identification message to the backend via the second communication channel;
• subsequent to sending the attestation that the second identification message matches the first identification message, receive by the user device a second step authorization instruction from the backend via the second communication channel;
• assess by the user device the identity of a user;
• and
• deliver an authorization response to the backend via the second communication channel based on the assessed identity of the user.

A system for mutually authenticated communications, the system comprising:

• a user device comprising:
• a memory comprising a private key;
• and
• a processor, wherein the processor is configured to:
• create a first communication channel with a backend;
• create a secure session across a second communication channel with the backend;
• receive a first identification message from the backend via the second communication channel;
• receive a second identification message from the backend via the first communication channel;
• send an attestation that the second identification message matches the first identification message to the backend via the second communication channel;
• subsequent to sending the attestation that the second identification message matches the first identification message, receive a second step authorization instruction from the backend via the second communication channel;
• assess the identity of a user;
• and
• deliver an authorization response to the backend via the second communication channel based on the assessed identity of the user.
