ABSTRACT:
A method for detecting and locating occurrence in a data stream of any complex string belonging to a predefined complex dictionary is disclosed. A complex string may comprise an arbitrary number of interleaving coherent strings and ambiguous strings. The method comprises a first process for transforming the complex dictionary into a simple structure to enable continuously conducting computationally efficient search, and a second process for examining received data in real time using the simple structure. The method may be realized by an article of manufacture comprising at least one processor-readable medium and instructions carried on the at least one medium. The instructions causes a processor to match examined data to an object complex string belonging to the complex dictionary, where the matching process is based on equality to constituent coherent strings, and congruence to ambiguous strings, of the object complex string.
