Embodiments disclosed herein extend to methods, systems, and computer program products for analyzing digital data. A source of digital data is analyzed and separated into segments, each segment having an identifiable characteristic. The separated segments are copied into planes of a higher dimension. The separated segments are compared to determine a resemblance factor. A fingerprint is generated for segments having a resemblance factor above a particular threshold. Based upon the generated fingerprint, a data source may be filtered to block or to pass data corresponding to the generated fingerprint. The digital data may be audio data, video data, or other data.
