Improving Audio Watermark Detection Using Noise Modelling and Turbo Coding
نویسندگان
چکیده
In this paper we present an improved error correction approach for digital audio watermarking. It uses a turbo coding algorithm that takes into account temporal variations of the host audio’s statistical properties, using a turbo decoder that estimates the unknown host audio distribution of the watermarked audio. Experimental results showed nearly one order of magnitude of the BER decrease during watermark extraction, compared to the basic turbo decoding that does not use noise estimation.

Audio Watermark Detection Improvement by Using Noise Modelling
In this paper we present an improved error correction approach for digital audio watermarking. It uses a turbo coding algorithm that takes into account temporal variations of the host audio’s statistical properties, using a turbo decoder that estimates the unknown host audio distribution in the watermarked audio. Experimental results showed nearly one order of magnitude of the BER decrease duri...
متن کاملIncreasing robustness of an audio watermark using turbo codes
Standard spread spectrum audio watermarking algorithms offer BER unacceptable for reliable transmission of data. Causes of unreliable watermark detection are often attacks that distort the watermarked audio in fading-like manner, disabling the correlation-based detectors to extract data. In this paper, consideration of capacity of the audio watermark channel in the presence of fading-like disto...
متن کاملA Secure and Robust Image Digital Watermarking
The digital watermarking is used to protect the intellectual property rights in the multimedia field. It consists of algorithms which embed in digital multimedia data such as video, image or audio, an invisible information related to its owner and its. In order to protect the watermarked data, a cryptographically secure pseudo-noise signal is needed. In this paper we propose a technique for gen...
متن کاملImproved Performance of Spread Spectrum Audio Watermarking Technique, by reducing the Cost Function Using 6 Bipolar Vectors
Digital watermarking is an approach to inserting invisible or visible marks into a digital multimedia data for further detection of correct ownership at the later stages. Most of the watermarking techniques focus on image and audio file, and several are related to audio file. The proposed work concentrates on improving the performance of spread spectrum audio watermarking technique. Audio water...
متن کاملDigital Watermarking Robustness and Fragility Characteristics: New Modelling and Coding Influence
This paper, introduces a new methodology for the design and analysis of digital watermarking systems which, from an information theoretic point of view, incorporates robustness and fragility. The proposed methodology is developed by focusing on the probability of error versus watermark-to-noise ratio curve, describing the technique performance, and a scenario for coded techniques which takes in...
