Abstract

There is provided a system and method for audio challenges for providing human response verification. There is provided a method comprising receiving a request to verify whether a client is human controlled, generating, using a database, a challenge question and a corresponding answer set, selecting a plurality of images and an audio instruction corresponding to the challenge question, presenting the plurality of images and the audio instruction to the client, receiving a submission to the challenge question from the client, and responding to the request by verifying whether the submission is contained in the answer set to determine whether the client is human controlled. By utilizing easily understood elements such as common shapes and objects, familiar characters, colors, sizes, orientations, and sounds, even young children can solve the challenge question, whereas automated systems are deterred by the complex audio and image analysis required.

Claims

1. A method for administering an audio challenge for providing human response verification, the method comprising:

receiving a request to verify whether a client is human controlled;

generating, using a database, a challenge question and a corresponding answer set;

selecting a plurality of images and an audio instruction corresponding to the challenge question;

presenting the plurality of images and the audio instruction to the client;

receiving a submission to the challenge question from the client; and

responding to the request by verifying whether the submission is contained in the answer set to determine whether the client is human controlled.

2. The method of claim 1, wherein the presenting of the audio instruction is by outputting to a speaker of the client.

3. The method of claim 1, wherein the selecting further uses a locale of the client to select the audio instruction localized in a language of the locale.

4. The method of claim 1, wherein the plurality of images comprise a plurality of characters, and wherein the challenge question comprises distinguishing between the plurality of characters.

5. The method of claim 1, wherein the plurality of images comprise a plurality of common objects, and wherein the challenge question comprises distinguishing between the plurality of common objects.

6. The method of claim 1, wherein the plurality of images comprise a plurality of colors, and wherein the challenge question comprises distinguishing between the plurality of colors.

7. The method of claim 1, wherein the plurality of images comprise a plurality of sizes, and wherein the challenge question comprises distinguishing between the plurality of sizes.

8. The method of claim 1, wherein the plurality of images comprise a plurality of orientations, and wherein the challenge question comprises distinguishing between the plurality of orientations.

9. The method of claim 1, wherein the plurality of images comprises a video clip, and wherein the challenge question comprises identifying objects visible in the video clip.

10. The method of claim 1, wherein the challenge question comprises identifying sounds audible in the audio instruction.

11. A server for administering an audio challenge for providing human response verification, the server comprising:

a processor configured to;

receive a request to verify whether a client is human controlled;

generate, using a database, a challenge question and a corresponding answer set;

select a plurality of images and an audio instruction corresponding to the challenge question;

present the plurality of images and the audio instruction to the client;

receive a submission to the challenge question from the client; and

respond to the request by verifying whether the submission is contained in the answer set to determine whether the client is human controlled.

12. The server of claim 11, wherein the processor is further configured to present the audio instruction by outputting to a speaker of the client.

13. The server of claim 11, wherein the processor is further configured to select by using a locale of the client to select the audio instruction localized in a language of the locale.

14. The server of claim 11, wherein the plurality of images comprise a plurality of characters, and wherein the challenge question comprises distinguishing between the plurality of characters.

15. The server of claim 11, wherein the plurality of images comprise a plurality of common objects, and wherein the challenge question comprises distinguishing between the plurality of common objects.

16. The server of claim 11, wherein the plurality of images comprise a plurality of colors, and wherein the challenge question comprises distinguishing between the plurality of colors.

17. The server of claim 11, wherein the plurality of images comprise a plurality of sizes, and wherein the challenge question comprises distinguishing between the plurality of sizes.

18. The server of claim 11, wherein the plurality of images comprise a plurality of orientations, and wherein the challenge question comprises distinguishing between the plurality of orientations.

19. The server of claim 11, wherein the plurality of images comprises a video clip, and wherein the challenge question comprises identifying objects visible in the video clip.

20. The server of claim 11, wherein the challenge question comprises identifying sounds audible in the audio instruction.
