1. In a computing system environment, a method of filtering to users relevancy data available from one or more computing devices, comprising: from a plurality of original files on the one or more computing devices, each file representing an underlying original bits of data and representative of a relevancy topic, creating a key in a multi-dimensional mapping space for the relevancy topic wherein the multi-dimensional mapping space is defined by an N-dimensional space according to a number of symbols N corresponding to the underlying original bits of data, said key being created by defining a digital spectrum of each of said plurality of files from an entirety of said original bits of data of said plurality of files, aggregating each said digital spectrum of each of said plurality of files, and plotting said aggregated digital spectrum as defining a single point in the multi-dimensional mapping space representing the relevancy topic for said plurality of original files; and determining whether new data on the one or more computing devices is sufficiently related to the relevancy topic by being within a predefined closeness of the key in the multi-dimensional mapping space.
5. The method of claim 1 , further including determining whether the new data is said sufficiently related by being within a predetermined distance of the key in the multi-dimensional mapping space.
