ABSTRACT
Digital watermarking is a technique used for preventing illegal copying and tampering of data. It is similar to the paper watermarking. It is mainly used for two purposes: authentication of data and copyrighting. Using copyrighting we can trace illegal copies of digital data and certify original owners. Also in case of dispute over a data the watermark can be used to prove the ownership. In watermarking the original data is superimposed with a signal containing the copyrighting information. This signal is not per ....etc

Digital Audio Watermarking
Digital watermarking is a technology which allows a secret message to be hidden in a computer file, without the detection of the user.Digital audio watermarking involves the concealment of data within a discrete audio file. Intellectual property protection is currently the main driving force behind research in this area though there are a lot of other applications. To combat online music piracy, a digital watermark could be added to all recording prior to release, signifying not only the author of the work, bu ....etc
