Systems, methods, and apparatus to monitor mobile internet activity

1. A method to monitor Internet activity of mobile computing devices, the method comprising:

determining, by executing an instruction with a processor, if a media request originated from a desktop computer or a mobile device by inspecting a user agent identifier of the media request;

if the media request originated from the desktop computer, blocking, by executing an instruction with a processor, the media request to prevent the media request originating from the desktop computer from affecting a mobile device media exposure monitoring result; and

if the media request originated from the mobile device, storing an identifier of the media requested by the media request in association with the mobile device.

2. The method as defined in claim 1 , further including storing a portion of the media in association with an identifier of the mobile device if the media request originated from the mobile device.

3. The method as defined in claim 1 , further including, if the media request originated from the mobile device:

determining if an application identified by the user agent identifier supports authentication; and

not requesting authentication credentials if the application does not support authentication.

4. The method as defined in claim 1 , further including:

determining if valid credentials are supplied in association with the media request;

transmitting a request for credentials to the mobile device if (1) the user agent identifier substantially matches a pattern of applications that support authentication, (2) valid credentials are not supplied in association with the media request, and (3) the media request originated from the mobile device; and

transmitting media identified by the media request to the mobile device if (1) the user agent identifier substantially matches the pattern of applications that support authentication, (2) valid credentials are supplied in association with the media request, and (3) the media request originated from the mobile device.

5. The method as defined in claim 4 , further including determining a panelist identifier associated with the credentials with the identifier of the media request.

6. The method as defined in claim 1 , further including instructing the mobile device to transmit media requests via a proxy server.

7. The method as defined in claim 6 , further including:

transmitting the credentials and an Internet proxy address of the proxy server to the mobile device; and

causing the mobile device to transmit subsequent requests for media to the proxy server.

8. A proxy server to service media requests from a media device, the proxy server comprising:

a request port to receive a media request;

an Internet port to retrieve media based on the media request;

a request servicer to determine if (1) the media device is a mobile device or a desktop computer, (2) block the media request if the media device is the desktop computer to prevent the media request originating from the desktop computer from affecting a mobile device media monitoring result, and (3) service the media request if the media device is the mobile device; and

a database to store an identification of the media requested via the request port in association with a panelist identifier if the media device is the mobile device.

9. The proxy server as defined in claim 8 , wherein:

the request servicer is to determine if (1) a user agent identifier of the media request received by the request port identifies an application which supports proxy authentication, and (2) valid credentials are provided in association with the media request received by the request port; and

the database is to store the identification if (1) the user agent identifier identifies the application that supports proxy authentication, and (2) valid credentials are provided in association with the request.

10. The proxy server as defined in claim 8 , further including:

a registrar to register the media device, to uniquely assign credentials to the media device, and to generate a configuration document to transmit the credentials and an Internet proxy address to the media device.

11. The proxy server as defined in claim 10 , wherein the registrar is to store an association between the credentials, the panelist identifier, and the media device in the database.

12. The proxy server as defined in claim 8 , wherein the request servicer is to store the media request from the media device in the database if the media device is the mobile device but not if the media device is the desktop computer.

13. The proxy server as defined in claim 8 , wherein the request servicer is to store the retrieved media transmitted to the media device in the database if the media device is the mobile device but not if the media device is the desktop computer.

14. The proxy server as defined in claim 8 , wherein the proxy server is to receive the media request and transmit the requested media via a wireless network.

15. A tangible machine-readable storage medium comprising instructions which, when executed, cause a machine to at least:

examine a user agent identifier of a received media request to determine whether the media request originated from a desktop computer or a mobile device;

if the media request originated from the desktop computer, block the media request to prevent the media request originating from the desktop computer from affecting a mobile device media monitoring result; and

if the media request originated from the mobile device, store an identifier of the media requested by the media request in association with the mobile device.

16. The tangible machine readable storage medium as defined in claim 15 , wherein the instructions, when executed, cause the machine to store a portion of the media in association with an identifier of the mobile device if the media request originated from the mobile device.

17. The tangible machine readable storage medium as defined in claim 15 , wherein the instructions, when executed, cause the machine to, if the media request originated from the mobile device:

determine if an application identified by the application identifier supports authentication; and

not request authentication credentials if the application does not support authentication.

18. The tangible machine readable storage medium as defined in claim 15 , wherein the instructions, when executed, cause the machine to:

determine if valid credentials are supplied in association with the media request;

transmit a request for credentials to the mobile device if (1) the user agent identifier substantially matches a pattern of applications that support authentication, (2) valid credentials are not supplied in association with the media request, and (3) the media request originated from the mobile device; and

transmit media identified by the media request to the mobile device if (1) the user agent identifier substantially matches the pattern of applications that support authentication, (2) valid credentials are supplied in association with the media request, and (3) the media request originated from the mobile device.

19. The tangible machine readable storage medium as defined in claim 15 , wherein the instructions, when executed, cause the machine to instruct the mobile device to transmit media requests via a proxy server.

20. The tangible machine readable storage medium as defined in claim 19 , wherein the instructions, when executed, cause the machine to:

transmit the credentials and an Internet proxy address of the proxy server to the mobile device; and

cause the mobile device to transmit subsequent requests for media to the proxy server.
