Robust spread-spectrum audio watermarking
We present several mechanisms that enable effective spreadspectrum audio watermarking systems: prevention against detection desynchronization, cepstrum filtering, and chess watermarks. We have incorporated those techniques them into a system capable of reliably detecting a watermark in an audio clip that has been modified using a composition of attacks that degrade the original audio characteri...
متن کاملToward robust spread spectrum watermarking of 3D data Toward robust spread spectrum watermarking of 3D data
This study addresses the issue of robust watermarking techniques for 3D objects. Taking into account that the literature is quite scarce in this respect, an original oblivious method is advanced. This method is obtained out of extending and generalising the principles we derived for video watermarking. The experimental results, obtained on several types of 3D objects (humanoids, spare parts, et...
متن کاملImage Watermarking Using Spread Spectrum Technique
Abstract In this paper, we propose to embed the watermark information in the log-2-spatio domain by means of spread spectrum technique. In log-2-spatio domain, the variance of the information is reduced significantly. This improves the efficiency and robustness of spread spectrum technique. Low intensity and mid-band regions are selected to embed the information in order to guarantee an invisib...
متن کاملSecure spread spectrum watermarking for multimedia
This paper presents a secure (tamper-resistant) algorithm for watermarking images, and a methodology for digital watermarking that may be generalized to audio, video, and multimedia data. We advocate that a watermark should be constructed as an independent and identically distributed (i.i.d.) Gaussian random vector that is imperceptibly inserted in a spread-spectrum-like fashion into the percep...
متن کاملSpread spectrum robust watermarking for NURBS surfaces
This paper presents a robust watermarking method for 3D data represented as NURBS. The mark is generated starting from a public message on 64 bits and from a secret information on 22 bits. The mark is embedded into the Discrete Cosine Transform (DCT) coefficients corresponding to the control points, by means of a spread spectrum technique. The detection procedure does not require the original (...
