Robust Hybrid Watermarking using Image and Audio against Synchronization Attacks

Hybrid Watermarking Approach is one of the trending approaches in the field of information security. Watermarking has a variety of applications to ensure data authentication, security, verification and copyrights protection of digital media. The proposed approach is hybrid watermarking applied on image and audio. We proposed a scheme in which the image is blindly embedded over original data with the help of Discrete Wavelength Transformation(DWT) and Singular value decomposition(SVD). Now the watermarked image is embedded into an audio signal by taking advantage of the histogram by making a gathering of three neighboring bins having various samples into it and later histogram is pulled out from embedding range by quoting to the modified mean. There is appropriate security analysis of the hybrid watermarking with respect to robustness and imperceptibility mainly against synchronization attacks and we also analyze the robustness in the case of common attacks.
