Abstract :
An DSP algorithm of watermarking was addressed. In general, watermarking used for information hiding could be held up by the software inserting method and its usefulness is lost. A DSP card designed in this paper, which is connect to a PC parallel port, can avoid the software hold up. This is a hardware watermarking insertion system and cannot be controlled by the PC software so it is a safe watermarking insertion system.
