EffectiveWatermarking of Digital Audio and Image using Matlab Technique
Watermarking is a technique which allows an individual to add hidden copyright notices or other verification messages to digital audio, video, or image signals and documents. In our proposal, for Audio Watermarking, a Watermark is encrypted using RSA Algorithm and is embedded on the audio file...

| description | Watermarking is a technique which allows
an individual to add hidden copyright notices or other
verification messages to digital audio, video, or image
signals and documents. In our proposal, for Audio
Watermarking, a Watermark is encrypted using RSA
Algorithm and is embedded on the audio file using LSB
technique. LSB technique is an old technique which is not
very robust against attacks. Here, in audio watermarking we
have embedded the encrypted watermark on the audio file,
due to which removal of the watermark becomes least
probable. This would give the technique a very high
robustness. In the retrieval, the embedded watermark is
retrieved and then decrypted. This method combines the
robustness of Transform domain and simplicity of spatial
domain methods. For image Watermarking, DWT technique
is used. DWT technique is used in Image watermarking.
Here, we have embedded the watermark in the image as a
pseudo-noise sequence. This gives a remarkable security to
the image file as only if the exact watermark is known can
the embedded watermark be removed from the watermarked
image. |
