Methods and apparatus to validate a tag for media
First Claim
1. A method to validate a tag, the method comprising:
- obtaining, by executing an instruction with a processor, first identification information extracted from a first tag distributed with first media presented at a first presentation location;
obtaining, by executing an instruction with the processor, second identification information determined from at least one of a) inherent information of at least one of audio or video of the first media presented at the first presentation location or b) a watermark embedded in at least one of the audio or the video of the first media presented at the first presentation location;
comparing, by executing an instruction with the processor, the first identification information with the second identification information;
when first identification information does not substantially match the second identification information, preventing, by executing an instruction with the processor, the first tag from being used to report exposure of the first media;
after preventing the first tag from being used, obtaining, by executing an instruction with the processor, third identification information extracted from a second tag distributed with second media presented at a second presentation location; and
in response to determining that the second tag substantially matches the first tag, preventing, by executing an instruction with the processor, the second tag from being used to report exposure to the second media, wherein preventing the second tag from being used includes preventing the crediting of the second media as having been presented.

Abstract
Methods and apparatus to validate a tag for media are disclosed. An example method includes obtaining first identification information extracted from a tag distributed with media presented at a presentation location, obtaining second identification information determined from at least one of a) inherent information of at least one of audio or video of the media presented at the presentation location or b) a watermark embedded in at least one of the audio or the video of the media presented at the presentation, comparing the first identification information with the second identification information, and when first identification information does not substantially match the second identification information, preventing the tag from being used to report exposure of the media.

8. A tangible computer readable storage medium comprising instructions that, when executed, cause a machine to at least:
-
obtain first identification information extracted from a first tag distributed with first media presented at a first presentation location; obtain second identification information determined from at least one of a) inherent information of at least one of audio or video of the first media presented at the first presentation location or b) a watermark embedded in at least one of the audio or the video of the first media presented at the first presentation location; compare the first identification information with the second identification information; when first identification information does not substantially match the second identification information, prevent the first tag from being used to report exposure of the first media; after preventing the first tag from being used, obtain third identification information extracted from a second tag distributed with second media presented at a second presentation location; and in response to determining that the second tag substantially matches the first tag, prevent the second tag from being used to report exposure to the second media, wherein the instructions, when executed, cause the machine to prevent the second tag from being used by preventing the crediting of the second media as having been presented. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system comprising:
-
a central facility to obtain first identification information extracted from a first tag distributed with first media presented at a first presentation location; a meter to; obtaining second identification information determined from at least one of a) inherent information of at least one of audio or video of the first media presented at the first presentation location or b) a watermark embedded in at least one of the audio or the video of the first media presented at the first presentation location, and transmit the second identification to the central facility; wherein the central facility is to; compare the first identification information with the second identification information and, when the first identification information does not substantially match the second identification information, prevent the first tag from being used to report exposure of the first media; after preventing the first tag from being used, obtain third identification information extracted from a second tag distributed with second media presented at a second presentation location; and in response to determining that the second tag substantially matches the first tag, prevent the second tag from being used to report exposure to the second media, wherein the central facility is to prevent the second tag from being used by preventing the crediting of the second media as having been presented. - View Dependent Claims (16, 17, 18, 19, 20, 21)
