A Robust Data Hiding Scheme In Audio Signal Based On Double Density Dual Tree Discrete Wavelet Transform

M. V. Naga Raju, DR. P. Sailaja

The outline of this paper is that, we plot a twofold tree twofold thickness discrete wavelet transform (dwt), given the first channel bank.. The procured channels are then refined by nonlinear streamlining, such that they satisfy flawless changing commitments and the following sets of wavelets have the analyticity property. We show two instances of arrange that are through and through preferable over those got with a past method. We demonstrate the power of the shrouded watermark for added substance clamor, Mp3 squeezing, re-quantization, sifting, editing and testing. The correlation examination demonstrates that our system has preferred execution over watermarking plans reported as of late.
