AUDIO WATERMARKING IN DIGITAL IMAGE USING WAVELET TRANSFORM
Digital watermarking is the act of hiding a message related to a digital signal (i.e. an image, song, video) within the signal itself. It is a concept closely related to steganography, in that they both hide a message inside a digital signal The rapid development in digital technologies has necessitated the owners to pay great attention in protecting their digital contents. Watermarking is used for content authentication and ownership protection. Biometric data provide unique means for individual identification. Biometric watermarking refers to the incorporation of biometric data in watermarking technology. By embedding biometrics in the host, it formulates a reliable individual identification as biometrics possesses exclusive characteristics that can be hardly counterfeited. In this paper we proposed a method of embedding owner's speech signal. Speech being a biometric data, the watermark signal in this method is expected to be more meaningful and has closer correlation with copyright holder.
