Embodiments disclosed herein are directed to systems and methods for enabling the matching of third party data with access providers' subscriber data in a privacy compliant manner, and then connecting an internet user to that third party data for use by marketers, content providers, or other interested parties in a manner that protects consumer privacy at all times. In one embodiment, an access provider such as an ISP sends its subscriber data to a double blind processor that generates an encrypted key for each subscriber. The key is then used to find matching consumer data, for example, consumer segments that represent previously collected or modeled consumer attitudinal, habit, or financial data. The key may be forwarded to a real time marketing bureau, which may use the matched data in subsequent real-time or substantially real-time operations to provide consumer or business data to advertisers, content providers, and other interested parties.
