Abstract: PURPOSE: A system and method for hierarchically inserting/detecting watermarks are provided to insert and detect different watermarks hierarchically. CONSTITUTION: A system for hierarchically inserting watermarks includes the first and second hierarchical watermark inserting units(220,230). The first and second hierarchical watermark inserting units. The first hierarchical watermark inserting unit receives data into which the watermarks is inserted and inserting the first hierarchical watermark into the data. The second hierarchical watermark inserting unit inserts the second hierarchical watermark independent of the first hierarchical watermark into the data into which the first hierarchical watermark has been inserted. The first hierarchical watermark inserting unit inserts an echo watermark into the overall input data. The second hierarchical watermark inserting unit adds a modulated pseudo noise progression to the first hierarchical watermarked data to generate watermarked data.
