Methods and apparatus to collect distributed user information for media impressions and search terms
An example method includes receiving a media identifier and a first impression identifier from a media device, the media identifier being indicative of media presented at the media device, receiving the first impression identifier in association with first user information from a first database proprietor as a result of the first database proprietor obtaining a first identifier encrypted with a first encryption key by the media device, and receiving a second impression identifier in association with second user information from a second database proprietor as a result of the second database proprietor obtaining a second identifier encrypted with a second encryption key. The example method further includes identifying the first user information as associated with a user based on the first impression identifier, identifying the second user information as not associated with the user based on the second impression identifier and discarding the second user information.
