5. The assembler of claim 1 , wherein each of the minimum multimedia data elements is associated with signatures respective of at least four angular permutations of the minimum multimedia data element.

6. The assembler of claim 5 , wherein the at least four angular permutations include rotation of the minimum multimedia data element by 0 degree, 90 degrees, 180 degrees, and 270 degrees.

7. The assembler of claim 1 , wherein the plurality of minimum size multimedia data elements are partitions of a portion of the input multimedia data element.

8. The assembler of claim 1 , wherein the input multimedia data element is selected from a group consisting of an image, graphics, a video stream, a video clip, an audio stream, an audio clip, a video frame, a photograph, images of signals, combinations thereof, and portions thereof that are not a minimum size multimedia data element.

9. The assembler of claim 8 , wherein the images of signals are images selected from a group consisting of medical signals, geophysical signals, subsonic signals, supersonic signals, electromagnetic signals, and infrared signals.

10. A method for generating a complex signature of an input multimedia data element, comprising:

receiving a plurality of signatures respective of a plurality of minimum size multimedia data elements, wherein each of the plurality of the minimum size multimedia data elements is a minimal partition of the input multimedia data element, and wherein a signature is generated from multiple patches of a random length and a random position of the input multimedia data element, wherein the signature is generated by a plurality of independent and random computational cores;

combining the plurality of signatures respective of the plurality of minimum size multimedia data elements to generate the complex signature; and

storing at least the complex signature in a storage unit connected thereto.
