Description: Firstly, research on robust image watermarking. A digital watermarking scheme based on wavelet transform was proposed. It realizes the watermarking extract without the original image using 64×64×8 bit gray image as the watermark signal. In order to enhancing the security of the watermark, we employ an encryption technology based on chaos and bit plan. Simulation results show that our scheme have good invisibility and can survive low-quality JPEG compression, median filtering and so on. In addition, the analysis of the extracted watermark can help us to detect and localize tampers. Platform: |

Description: All three, Discrete Wavelet Transform (DWT) - Singular
Value Decomposition (SVD) and Adaptive Tabu Search
(ATS) have been used as mathematical tools for embedding
data into an audio signal. In this paper, we present a new
robust audio watermarking scheme based on DWT-SVD and
ATS. After applying the DWT to the cover audio signal, we
map the DWT coefficients, and apply the SVD, we search for
the optimal intensity of audio watermarking by using the
ATS. Experimental results show that the watermarking
method performs well in both security and robustness to
many digital signals processing, such as filtering,
cropping, mp3 and random noise. Platform: |
