Systems and methods for authenticating a user at a public terminal
Systems and methods for authenticating a user to access a public terminal are described. Disclosed embodiments may include reading, using the physical credential reader, a user identifier from the physical credential device. Disclosed embodiments may also include transmitting the public terminal identifier and the user identifier to a secure server. Further, disclosed embodiments may include receiving, after completing the transmission, a unique code from the secure server. Disclose embodiments may additionally include displaying the unique code on the display device. Disclosed embodiments may include receiving, after displaying the unique code, an authentication message from the secure server. Disclosed embodiments may further include, responsive to receiving the authentication message, authorizing the user to use a terminal command at the public terminal.
1. A public terminal having an identifier, comprising:
at least one processor;
a display device;
a physical credential reader configured to read a physical credential device of a user; and
a storage medium storing instructions that, when executed, configure the at least one processor to perform operations comprising:
reading, using the physical credential reader, a user identifier from the physical credential device;
transmitting the public terminal identifier and the user identifier to a secure server;
receiving, after completing the transmission, a unique code generated by the secure server;
displaying the server-generated unique code on the display device;
receiving, after displaying the server-generated unique code, a remote session authentication message from the secure server indicating a mobile device associated with the user identifier:
captured the displayed unique code,
provided the captured unique code to the secure server, and
provided valid password input data based on a user profile retrieved by the secure server and associated with the unique code; and
responsive to receiving the remote session authentication message, authorizing the mobile device to control one or more operations of the public terminal.
2. The public terminal of claim 1 , wherein:
the display device comprises an electronic ink display.
3. The public terminal of claim 2 , wherein:
the unique code comprises a quick-response code; and
displaying the unique code comprises displaying the quick-response code on the electronic ink display.
4. The public terminal of claim 3 , wherein:
the quick-response code comprises a black-and-white quick response code.
5. The public terminal of claim 1 ,
further comprising an infrared transmitter;
wherein:
the unique code comprises an infrared transmission code, and
displaying the unique code comprises transmitting the infrared transmission code using the infrared transmitter.
6. The public terminal of claim 1 ,
further comprising an infrared transmitter;
wherein:
the unique code comprises an infrared transmission code and a quick-response code, and
displaying the unique code comprises:
transmitting the infrared transmission code using the infrared transmitter; and
displaying the quick-response code on the display device.
7. The public terminal of claim 1 , wherein:
the physical credential device comprises a transaction card having a magnetic strip; and
the magnetic strip comprises an encoded user identifier.
8. The public terminal of claim 1 , wherein:
the physical credential device comprises a transaction card having a magnetic strip and an electronic circuit; and
the user identifier comprises an identifier generated from data contained in the magnetic strip and in the electronic circuit.
9. The public terminal of claim 1 , wherein:
the public terminal comprises an automatic teller machine.
10. The public terminal of claim 1 , wherein:
the unique code comprises a code based on a cryptographic hash function.
11. The public terminal of claim 1 , wherein:
the unique code comprises a code based on a cryptographic hash function of the public terminal identifier and the user identifier.
