1. A method of measuring exposure to streaming media, the method comprising:
- extracting a watermark from media;
converting the media into converted media having a streaming format;
transmitting, from a service provider server to an audience measurement entity, a request for (1) an encryption key and (2) a decryption key location, the request for the encryption key including the watermark extracted from the media;
storing, at the service provider, (1) the requested encryption key, and (2) the decryption key location, the decryption key location identifying an address of a server of the audience measurement entity;
encrypting, at the service provider server, the converted media using the requested encryption key, the requested encryption key associated with the watermark; and
creating a manifest in association with the converted media, the manifest identifying a location of the encrypted media and the decryption key location.

9. An apparatus to measure exposure to streaming media, the apparatus comprising:
-
a media identifier located at a service provider to generate media-identifying metadata based on a watermark extracted from the media; an encryption key synchronizer located at the service provider to request an encryption key and a location of a decryption key from an audience measurement entity different from the service provider, the request including the media-identifying metadata; an encryption key store to store the requested encryption key and the location of the decryption key in association with the media, the location of the decryption key identifying an address of a server of the audience measurement entity; a media encrypter located at the service provider to encrypt the media using the requested encryption key after receipt of the requested encryption key and the location of the decryption key at that encryption key synchronizer; and a manifest generator to generate a manifest identifying a location of the encrypted media and the location of the decryption key. - View Dependent Claims (10, 11, 12)

13. A tangible computer-readable storage medium comprising instructions which, when executed, cause a service provider server to at least:
-
extract a watermark from media; convert the media into converted media having a streaming format; transmit, to an audience measurement entity, a request for (1) an encryption key and (2) a decryption key location, the request for the encryption key including the watermark extracted from the media; store, at the service provider, (1) the requested encryption key, and (2) the decryption key location, the decryption key location identifying an address of a server of the audience measurement entity; encrypt the converted media using the requested encryption key, the requested encryption key associated with the watermark; and create a manifest in association with the encrypted converted media, the manifest identifying a location of the encrypted converted media and the decryption key location. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
