Method and system for verification of human presence at a mobile device

1. A method for authentication of a human at a communication device, the method comprising:

receiving, via a first communication device of the human, a request for authentication of the human at a second communication device;

sending a Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) challenge to the first communication device;

receiving a response to the CAPTCHA challenge, the response being received at one of the first and second communication device; and

authenticating the human upon a positive match between the response received to the CAPTCHA challenge sent.

2. The method recited in claim 1 , wherein sending the CAPTCHA challenge comprises generating the CAPTCHA challenge.

3. The method recited in claim 1 , wherein the CAPTCHA challenge is generated by a third party server.

4. The method recited in claim 1 , wherein the CAPTCHA challenge is sent via a multi-media message (MMS), a SMS, a voice call, an Email, and a video call.

5. The method as recited in claim 1 , wherein the CAPTCHA challenge is one or more of an image, a video, a question, a motion, an interaction, an audio and a vibration.

6. The method as recited in claim 1 , wherein the response is one or more of a text, a voice, a motion and an interaction.

7. The method as recited in claim 1 , wherein the first and second communication devices are selected from a group consisting of a desktop, a laptop, a mobile phone, a tablet PC, a netbook, an e-book reader and a PDA.

8. The method as recited in claim 1 , wherein the request for authentication is received over internet.

9. The method as recited in claim 1 , wherein the request for authentication is received from a web server.

10. The method of claim 1 , wherein the request for authentication includes an identification of the communication device.

11. The method of claim 10 , wherein the identification is a mobile phone number of the communication device.

12. A system for authentication of a human at a communication device, the system comprising:

a request reception module for receiving, via a first communication device of the human, a request for authentication of the human at a second communication device;

a code module for sending a Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) challenge to the first communication device;

a response reception module for receiving a response to the CAPTCHA challenge, the response being received at one of the first and second communication device; and

an authentication module for authenticating the human upon a positive match between the response received to the CAPTCHA challenge sent.

13. The system recited in claim 12 , wherein the code module comprises a code generation module for generating the CAPTCHA challenge.

14. The system recited in claim 12 , wherein the code module comprises a code reception module for sending the CAPTCHA challenge generated by a third party server.

15. The system recited in claim 12 , wherein the code module is capable of sending the CAPTCHA challenge via a multi-media message (MMS), a SMS, a voice call, an Email and a video call.

16. The system as recited in claim 12 , wherein the CAPTCHA challenge is one or more of an image, a video, a question, a motion, an interaction, an audio and a vibration.

17. The system as recited in claim 12 , wherein the response reception module is capable of receiving the response via one or more of a text, a voice, a motion and an interaction.

18. The system as recited in claim 12 , wherein the communication devices are selected from a group consisting of a desktop, a laptop, a mobile phone, a tablet PC, a netbook, an e-book reader and a PDA.

19. The system of claim 12 , wherein the request for authentication includes an identification of the communication device.

20. The system of claim 19 , wherein the identification is a mobile phone number of the communication device.
