Microsoft has invented a technology for digital rights management that some experts are saying is unbreakable. It is dubbed “stealthy audio watermarking.” It permanently inserts the content producer’s name within the MP3 and .WAV files – based on similar spread-spectrum technology used by the military. To really work, it would require that devices be designed to refuse to play a file that isn’t properly watermarked, according to a posting on the Wolf’s Den blog.
Should this concept take off, it could put an end to the seemingly unstoppable trend of illegal music swapping. Big that’s a big if.
