Abstract: A software application for creating and distributing non-sensitized summaries from sensitized data aggregated on behalf of users is provided. The software application comprises, a data processing portion of the software for de-sensitizing data and incorporating the de-sensitized data into the form of a data summary, a data caching portion of the software for storing, managing, and serving non-sensitive data summaries and a user-interface portion of the software for enabling requests for data summaries and for enabling display of the requested summaries. A user operating the interface portion of the software initiates a request to the data-caching portion of the software, the request triggering service of a completed, non-sensitive data summary or summaries created by the data processing portion of the software. In preferred embodiments, the software is implemented on cooperating nodes connected to a data-packet-network, which may be the Internet network.
