Abstract

A system, method, and computer-readable medium for challenge-response authentication are provided. A plurality of codes is received over a communication network based on input provided by way of a user interface displaying a plurality of images. An alphanumeric string is generated based on the received plurality of codes and based on a table that associates each one of the plurality of codes with a respective one of the plurality of images and with a respective one of a plurality of alphanumeric characters. A determination is made as to whether to grant authorization based on whether the generated alphanumeric string matches an alphanumeric user identifier stored in a memory device in association with a user.

Claims

1. A method comprising:

displaying, by a terminal and on a user interface, a first arrangement of a plurality of images,

wherein one or more of a plurality of codes correspond to one of the plurality of images, and

wherein one or more of a plurality of codes correspond to an alphanumeric character of a plurality of alphanumeric characters;

receiving, by the terminal, an input comprising rearranged locations of the plurality of images in a rearranged order on the user interface;

ordering, by the terminal, the plurality of codes in a sequence based on the rearranged order of the plurality of images; and

transmitting, by the terminal and over a communication network, the sequence of the plurality of codes.

2. The method of claim 1, wherein the first arrangement of the plurality of images displayed on the user interface is any one or a combination of:

a multidimensional grid of the plurality of images, a horizontal arrangement of the plurality of images, or a spatial overlay of the plurality of images.

3. The method of claim 1, further comprising generating a second arrangement of the plurality of images based on the input received through the user interface, wherein the ordering step includes sequencing the plurality of codes based on the second arrangement of the plurality of images.

4. The method of claim 3, wherein:

the second arrangement includes at least two images of the plurality of images arranged in an order, and

the codes are ordered in the sequence in which the corresponding image is arranged in the second arrangement.

5. The method of claim 1, wherein:

the input received through the user interface includes the selection of at least two images of the plurality of images in an order, and

the sequence of the plurality of codes is based on the order in which the corresponding image was selected.

6. The method of claim 1, further comprising:

transmitting, by the terminal over the communication network, a request for a service to a service network; and

receiving, by the terminal over the communication network, access to the service on the service network when an alphanumeric string matches a user identifier, the alphanumeric string being generated from the plurality of alphanumeric characters based on the sequence of the corresponding the plurality of codes.

7. The method of claim 1, further comprising encrypting the sequence of codes transmitted over the communication network.

8. The method of claim 1, wherein the plurality of codes are distinct from the plurality of alphanumeric characters.

9. The method of claim 1, wherein the input is received on the user interface of the terminal.

10. A terminal comprising:

a processor,

a tangible, non-transitory memory configured to communicate with the processor,

the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the processor to perform operations comprising;

displaying, by the terminal and on a user interface, a first arrangement of a plurality of images,

wherein one or more of a plurality of codes correspond to one of the plurality of images, and

wherein one or more of a plurality of codes correspond to an alphanumeric character of a plurality of alphanumeric characters;

receiving, by the terminal, an input comprising rearranged locations of the plurality of images in a rearranged order on the user interface;

ordering, by the terminal, the plurality of codes in a sequence based on the rearranged order of the plurality of images and

transmitting, by the terminal and over a communication network, the sequence of the plurality of codes.

11. The terminal of claim 10, wherein the first arrangement of the plurality of images displayed on the user interface is any one or a combination of:

a multidimensional grid of the plurality of images, a horizontal arrangement of the plurality of images, or a spatial overlay of the plurality of images.

12. The terminal of claim 10, the operations further comprising:

generating a second arrangement of the plurality of images based on the input received through the user interface, and

sequencing the plurality of codes based on the second arrangement of the plurality of images.

13. The terminal of claim 12, wherein:

the second arrangement includes at least two images of the plurality of images arranged in an order, and

the codes are ordered in the sequence in which the corresponding image is arranged in the second arrangement.

14. The terminal of claim 10, wherein:

the input received through the user interface includes the selection of at least two images of the plurality of images in an order, and

the sequence of the plurality of codes is based on the order in which the corresponding image was selected.

15. The terminal of claim 10, the operations further comprising:

transmitting, over the communication network, a request for a service to a service network; and

receiving, over the communication network, access to the service on the service network when an alphanumeric string matches a user identifier, the alphanumeric string being generated from the plurality of alphanumeric characters based on the sequence of the corresponding the plurality of codes.

16. The terminal of claim 10, the operations further comprising encrypting the sequence of codes transmitted over the communication network.

17. The terminal of claim 10, wherein the plurality of codes are distinct from the plurality of alphanumeric characters.

18. The terminal of claim 10, wherein the input is received on the user interface of the terminal.

19. An article of manufacture including a non-transitory, tangible computer readable storage medium having instructions stored thereon that, in response to execution by a terminal, cause the terminal to perform operations comprising:

displaying, by the terminal and on a user interface, a first arrangement of a plurality of images,

wherein one or more of a plurality of codes correspond to one of the plurality of images, and

wherein one or more of a plurality of codes correspond to an alphanumeric character of a plurality of alphanumeric characters;

receiving, by the terminal, an input comprising rearranged locations of the plurality of images in a rearranged order on the user interface;

ordering, by the terminal, the plurality of codes in a sequence based on the rearranged order of the plurality of images and

transmitting, by the terminal and over a communication network, the sequence of the plurality of codes.

20. The article of claim 19, wherein the first arrangement of the plurality of images displayed on the user interface is any one or a combination of:

a multidimensional grid of the plurality of images, a horizontal arrangement of the plurality of images, or a spatial overlay of the plurality of images.
