But with the rapid growth in technology and internet  distribution of digital media, an urgent need for  copyright protection is been created because of easy  replication and modification.Traditionally the  authenticity and integrity of data was resolved using  techniques like cryptography and digital  signature.Cryptography is the science of writing data  in secret codes. But the cryptography does not always  provide safe communication, since the encrypted  message causes suspicion.Digital signature emphasized  protecting the rights of customer, but the drawback  of conventional schema is the extra bandwidth needed  for transmission of the signature.Watermarking is the  technique which emphasizes on protecting the right of  service provider.Digital watermarking is the process  of embedding information into a digital signal.
