Abstract
A method and system for generating a complex signature of a multimedia data element. The method comprises partitioning the multimedia data element recursively until a minimum size multimedia data element is reached; generating a signature for each minimum size multimedia data element; assembling at least a complex signature comprising a plurality of signatures of the minimum size multimedia data elements; and storing the signatures of each of the minimum size multimedia data elements and the complex signature of the multimedia data element in association with the multimedia data element and partitions thereof in a storage unit.
