Abstract
A fingerprinting apparatus, comprising: a plurality of receiving units to receive a plurality of input datasets, each of the plurality of input datasets divided into a plurality of input segments, at least one of the plurality of input datasets uniquely marked; a selector to select at least one input segment from one of at least two different input datasets of the plurality of input datasets; and at least one combiner to arrange the selected at least one input segment to produce an output dataset having a plurality of output segments, such that the number of output segments is equal to the number of input segments in each input dataset.
Claims28
A method of fingerprinting, comprising:
- receiving a plurality of master datasets, each master dataset divided into a plurality of input segments,
- wherein at least one master dataset of said plurality of master datasets is uniquely marked;
- and
- producing an output dataset having a plurality of output segments, each output segment of said output dataset generated by:
- selecting a corresponding input segment from one of said plurality of master datasets;
- and
- inserting said selected corresponding input segment into said each output segment,
- wherein the arrangement of said plurality of output segments in said output dataset as a result of selecting input segments from said plurality of master datasets provides fingerprinting of said output dataset such that the number of output segments in said output dataset is equal to the number of input segments in each master dataset.
