Quantum-based information protection

A method, comprising:

• sending, by a first device to a server via a quantum channel, verification information associated with a user of the first device, wherein the server receives first verification information corresponding to the verification information sent by the first device, the server determines that the first verification information fails to verify against second verification information;
• receiving, by the first device from the server, a request to provide additional verification information;
• and
• in response to receiving the request to provide the additional verification information, sending, by the first device to the server via a network different from the quantum channel, the additional verification information.

A system, comprising:

• at least one processing circuit each comprising at least one processor and at least one memory, wherein the at least one processor is configured to:
• receive, from a first device via a quantum channel, first verification information associated with a user of the first device;
• determine that the first verification information fails to verify against second verification information;
• in response to determining that the first verification information fails to verify, store the first verification information;
• in response to receiving, from a second device, the first verification information and device information of the second device, flagging the device information of the second device as a potential origin of fraud.
