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

Audio Watermarking



INTRODUCTION

Digital Data can be shared by multiple users, distributed over network, and managed for long period time without any damage.
In contrast to these, the copyright protection problem arises, since unauthorized copying and distribution of digital data are simplified, too.
As a result, a technique called digital watermarking is introduced to protect the ownership of these contents.
