14. The method of claim 12 , wherein the generating the concept structures from the SRCs, further comprising: for each SRC performing: generating metadata for the cluster of signatures included in the SRC; associating the generated metadata with the SRC; matching the SRC with a plurality of stored SRCs, wherein each of the plurality of stored SRCs that matches the SRC forms a concept structure, wherein the concept structure includes at least metadata associated with each SRC that is found to be a match.
16. The method of claim 14 , wherein the signatures are generated by a signature generator, wherein the signature generator comprises a plurality of computational cores, each computational core having properties statistically independent of each other of the computational cores, each computational core generates, responsive to a received MMDE at least a signature comprising a first signature element and a second signature element, the first signature element being a robust signature.
