Secure distributed information system for public device authentication

A system for performing user authentication, the system comprising:

• a service electronic device associated with a service;
• and
• a computer-readable storage medium comprising one or more programming instructions that, when executed, cause the service electronic device to:
• receive, from a public electronic device, a request for a user to initiate a session of the service,
• generate a first security token, a first write token, a first read token, and/or a first delete token,
• send the first security token, the first write token, the first read token, and/or the first delete token to a server electronic device,
• receive, from the server electronic device, a key location identifier that uniquely identifies a memory location of a data store associated with the server electronic device where the first security token, the first write token, the first read token, and/or the first delete token are stored,
• save the key location identifier in a data store associated with the service electronic device,
• generate a signed key location identifier,
• generate a machine-readable image that includes the signed key location identifier in an encoded format, and
• send the machine-readable image to the public electronic device.
