Evaluating the Performance of Audio Watermarking using Digital Delay Attack

Sukhwinder Kaur, Vijay Kumar Banga


A digital watermarking is a technique, which is used to defensive digital information like images, videos and audio as it provides copyright tenure. Digital watermarking emerges as techniques for defending the multimedia data from copyright infraction. It is a method for classification multi-media data, for example digital images, text documents, video and audio clips, by trouncing secret information in the data. In this paper various audio watermarking techniques are discussed. Audio watermarking is supplementary difficult than image watermarking due to the lively incomparability of hearing power over the visual field. The embedded watermark is a binary image. The different encryption and decryption techniques are used for hiding the secret image so no one concealing their existence. The embedding of an encryption watermark is distributed uniformly in the areas of low frequencies components is that these components energy is high enough to embed the watermark in such a way that the watermark is inaudible and it should not easy to remove. The various watermark techniques DCT, DWT, LSB have been designed and implemented in MATLAB tool. Various performance metrics has been taken for experimental purpose. It has been found that without attack and with digital delay attack DWT using HAAR is quite effective technique over others.


Keywords: Watermarking, DCT, DWT, LSB.
