Speech as a biometric watermark for digital images using stationary wavelet transform

The enormous 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 traits provide unique means for individual identification. Biometric watermarking refers to the incorporation of biometric 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.
