Abstract

In one embodiment, a human interactive proof portal 140 may use a biometric input to determine whether a user is a standard user or a malicious actor. The human interactive proof portal 140 may receive an access request 302 for an online data service 122 from a user device 110. The human interactive proof portal 140 may send a proof challenge 304 to the user device 110 for presentation to a user. The human interactive proof portal 140 may receive from the user device 110 a proof response 306 having a biometric metadata description 430 based on a biometric input from the user.

Claims

1. A machine-implemented method, comprising:

receiving an access request from a user device;

sending a proof challenge to the user device for presentation to a user; and

receiving from the user device a proof response having a biometric metadata description based on a biometric input from the user, the biometric metadata description describing at least one of a tone and/or a speed of the biometric input.

2. The method of claim 1, further comprising:

sending a conversion applet for installation by the user device.

3. The method of claim 1, further comprising:

comparing the biometric input to a proof challenge answer.

4. The method of claim 1, further comprising:

receiving a response representation based on an audio input.

5. The method of claim 4, further comprising:

determining if the audio input is from a speech synthesizer.

6. The method of claim 4, further comprising:

measuring a flatness aspect of the audio input.

7. The method of claim 4, further comprising:

comparing a voice print of the audio input to a user account profile.

8. The method of claim 4, further comprising:

identifying different users for a single user account.

9. The method of claim 4, further comprising:

identifying a voice print as belonging to a frequent user.

10. The method of claim 4, further comprising:

determining if the user is at a reputable network address.

11. The method of claim 1, further comprising:

tracking a response time for the proof response.

12. The method of claim 1, further comprising:

granting access to a user account based on the biometric input.

13. The method of claim 1, further comprising:

sending a text segment as the proof challenge.

14. The method of claim 1, further comprising:

sending an audio word as the proof challenge.

15. A tangible computer-readable storage medium having a set of instructions detailing a method stored thereon that when executed by one or more processors cause the one or more processors to perform the method, the method comprising:

sending an access request to a human interactive proof portal;

receiving a proof challenge from the human interactive proof portal for presentation to a user;

receiving an audio input from the user in response to the proof challenge; and

creating a biometric metadata description based on the audio input;

wherein the biometric metadata description describes at least one of a level, a tone, and/or a speed of the audio input; and

sending to the human interactive proof portal a proof response comprising the biometric metadata description to determine whether the audio input is produced by a human or is computer generated.

16. The tangible computer-readable storage medium of claim 15, wherein the method further comprises:

presenting an audio word as the proof challenge to the user.

17. The tangible computer-readable storage medium of claim 15, wherein the method further comprises:

presenting a text segment as the proof challenge to the user.

18. The tangible computer-readable storage medium of claim 15, wherein the method further comprises:

creating a response representation based on the audio input.

19. A human interactive proof portal, comprising:

a communication interface that receives an access request from a user device; and

a processor to generate a proof challenge for presentation to a user and to examine a proof response containing a representation of a biometric input from the user and a biometric metadata description, wherein the biometric metadata description describes at least one of a level, a tone, and a speed of the biometric input, to determine whether the user is from a human sweatshop.

20. The human interactive proof portal of claim 19, wherein the processor generates a biometric proof response.
