Distributed audience measurement systems and methods
First Claim
1. A method to meter media, the method comprising:
- waking a portable device from an inactive state in response to an activation signal received at the portable device from a central facility, the activation signal including a first fingerprint andafter waking the portable device from the inactive state;
storing the first fingerprint included with the activation signal in a memory of the portable device;
recording audio with the portable device;
generating, with the portable device, a second fingerprint based on the recorded audio;
comparing, with the portable device, the first fingerprint to the second fingerprint to generate a match score; and
communicating, from the portable device to the central facility, a match determination based on the match score.

Abstract
Systems and methods are disclosed for customizing, distributing and processing audio fingerprint data. An example method includes receiving, at a first device, an activation signal and a first audio fingerprint via first wireless communications between the first device and a communications network, the receiving occurring while the first device is not recording audio via a microphone of the first device; based on the activation signal, recording audio using the microphone during a first time period; generating a second audio fingerprint representative of the recorded audio; determining whether the second audio fingerprint matches the first audio fingerprint; and sending an indication of whether the second audio fingerprint matches the first audio fingerprint to an audience measurement entity via second wireless communications between the first device and the communications network.

1. A method to meter media, the method comprising:
-
waking a portable device from an inactive state in response to an activation signal received at the portable device from a central facility, the activation signal including a first fingerprint and after waking the portable device from the inactive state; storing the first fingerprint included with the activation signal in a memory of the portable device; recording audio with the portable device; generating, with the portable device, a second fingerprint based on the recorded audio; comparing, with the portable device, the first fingerprint to the second fingerprint to generate a match score; and communicating, from the portable device to the central facility, a match determination based on the match score. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A portable device comprising:
-
a communication interface to receive an activation signal from a central facility, the activation signal including a first fingerprint, the activation signal further including executable content to wake the portable device from an inactive state; a microphone to record an audio sample; a formation module implemented, at least in part, by at least one processor, the formation module to generate a second fingerprint based on the audio sample after the portable device wakes from the inactive state; and a confirmation module implemented, at least in part, by the at least one processor, the formation module to, after the portable device wakes from the inactive state; generate a match score based on the first fingerprint and the second fingerprint, and generate a match determination based on the match score. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A tangible machine readable storage medium comprising instructions which, when executed by a processor of a portable device, cause the processor to at least:
-
wake the portable device from an inactive state in response to an activation signal received at the portable device from a central facility, the activation signal including a first fingerprint and after the portable device wakes from the inactive state; store the first fingerprint included with the activation signal in a memory of the portable device; record audio with the portable device; generate a second fingerprint based on the recorded audio; compare the first fingerprint to the second fingerprint to generate a match score; and communicate, from the portable device to the central facility, a match determination based on the match score. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
