Robust multibit audio watermarking in the temporal domain
نویسندگان
چکیده
In this paper, a technique for temporal embedding of a multibit watermark on an audio signal is proposed. The method is based on generating a chaotic sequence which is used for modifying the audio samples. A chaotic sequence generates the watermark, while the parameters of the embedding procedure are chosen so as to minimize the perceivable distortion of the initial signal, while preserving the power of the watermark at a detectable level. The watermark is resistant to lowpass manipulation attacks, such as filtering or compression, and cropping attacks as well.

A Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...

متن کاملImage watermarking with feature point based synchronization robust to print-scan attack
In this paper we propose a content based multibit watermarking method robust to print–scan attack. A method to extract feature points, robust in terms of watermarking, is proposed. The location of the watermark is tied to a coordinate system defined by robust feature points. A message sequence is mapped to a directional angle of periodic patterns, which are scattered and embedded into triangles...
متن کاملAn improved hybrid image watermarking scheme in shearlet and wavelet domain
Watermarking is one of the best solutions for copyright protection and authentication of multimedia contents. In this paper a hybrid scheme is proposed using wavelet and shearlet transforms with singular value decomposition. For better security, Arnold map is used for encryption. Examining the results and comparing with other methods show that this hybrid proposed scheme with simultaneous utili...
متن کاملGeometric Robust Watermarking through Mesh Model Based Correction
While geometric attacks are one of the most challenging problems in watermarking, random bending is the most difficult to handle among all geometric attacks. Such attacks are difficult to correct by traditional parameter estimation or registration approaches. In this paper, we present a watermarking scheme based on a deformable mesh model to combat such attacks. The distortion is corrected usin...
