Abstract
Disclosed examples involve receiving a plurality of first identifiers and a media identifier collected by a data collector installed at a mobile device in connection with an application. The first identifiers identify at least one of the mobile device or a user of the mobile device. The media identifier is indicative of media presented via the application at the mobile device. Encrypted identifiers are generated by encrypting the first identifiers. Respective ones of the encrypted identifiers are decodable by corresponding database proprietors to which the respective encrypted identifiers pertain. The encrypted identifiers are sent in association with the media identifier to an audience measurement entity.
