Apparatus, system and methods for portable device tracking using temporary privileged access
View Patent ↗A computer-implemented system, apparatus and method for accessing a portable device to execute monitoring capabilities. The monitoring capabilities include packet detection, which in turn may be processed to produce media exposure data. The monitoring capabilities are installed using privileged access in order to obtain data from a kernel layer of the portable device, and the device is returned to an original state following installation, in order to comply with operating system requirements. Audio media exposure data may further be integrated with the packet-detected media exposure data.
1. A method for monitoring a portable device, the method comprising:
activating, by executing an instruction with a processor, a shell to access at least a kernel layer in the portable device;
verifying whether the shell has an elevated privilege;
in response to detecting that the shell does not have the elevated privilege, gaining the elevated privilege;
configuring a packet capturer to capture packets on the portable device using the elevated privilege when the shell is deactivated, the packet capturer to communicate between the kernel layer and a user layer of the portable device;
deactivating the shell; and
analyzing, by executing an instruction with the processor, the packets captured by the packet capturer to produce media exposure data.
2. The method of claim 1 , wherein the portable device includes at least one of a cell phone, smart phone and computer tablet.
3. The method of claim 1 , further including receiving audio media exposure data from the portable device.
4. The method of claim 3 , wherein the audio media exposure data comprises at least one of (i) ancillary code relating to audio, or (ii) audio signatures.
5. The method of claim 4 , wherein the ancillary code is formed from audio signals converted at least in part to a frequency domain.
6. The method of claim 1 , wherein the packet capturer is embodied on a shared memory in the portable device.
7. A tangible machine-readable storage disk or storage device comprising instructions which, when executed, cause a machine to at least:
activate a shell to access at least a kernel layer in the portable device;
verify whether the shell has an elevated privilege;
in response to detecting that the shell does not have the elevated privilege, gain the elevated privilege;
configure a packet capturer to capture packets on the portable device using the elevated privilege when the shell is deactivated, the packet capturer to communicate between the kernel layer and a user layer of the portable device;
deactivate the shell; and
analyze the packets captured by the packet capturer to produce media exposure data.
8. The tangible machine readable storage disk or storage device of claim 7 , wherein the portable device includes at least one of a cell phone, smart phone and computer tablet.
9. The tangible machine readable storage disk or storage device of claim 7 , wherein the instructions, when executed, further cause the machine to receive audio media exposure data from the portable device.
10. The tangible machine readable storage disk or storage device of claim 9 , wherein the audio media exposure data comprises at least one of (i) ancillary code relating to audio, or (ii) audio signatures.
11. The tangible machine readable storage disk or storage device of claim 10 , wherein the ancillary code is formed from audio signals converted at least in part to a frequency domain.
12. The tangible machine readable storage disk or storage device of claim 7 , wherein the packet capturer is embodied on a shared memory in the portable device.
