چکیده
The protection of multimedia data has become a necessity due to the generation of illegal copies, thus, the purpose of this article was to analyze and evaluate the algorithm of two-set in embedding a watermark into an audio signal. Metrics were analyzed as the Perceptual Evaluation of Audio Quality (PEAQ) by calculating the Objective Difference Grade (ODG) to verify the inaudibility of the watermark and the robustness of it against attacks from resampling and Additive White Gaussian Noise (AWGN) by estimating the Bit Error Rate (BER). The process was applied to hundred Waveform Audio Format (WAV) clips classifieds in five musical genders and we obtained an ODG value average of -0.83045 that according to the International Telecommunication Union (ITU), the watermark is slightly perceptible if you listen with extreme care.

Psychoacoustic Auditory Model and Spread Spectrum Theory
A new algorithm for embedding a digital watermark into an audio signal is proposed. It uses spread spectrum theory to generate a watermark resistant to different removal attempts and a psychoacoustic auditory model to shape and embed the watermark into the audio signal while retaining the signal’s perceptual quality. Recovery is performed without knowledge of the original audio signal. A softwa...
متن کاملTwo Novel Chaos-Based Algorithms for Image and Video Watermarking
In this paper we introduce two innovative image and video watermarking algorithms. The paper’s main emphasis is on the use of chaotic maps to boost the algorithms’ security and resistance against attacks. By encrypting the watermark information in a one dimensional chaotic map, we make the extraction of watermark for potential attackers very hard. In another approach, we select embedding po...

The intriguing characteristics of chaotic maps have prompted researchers to use these sequences in watermarking systems to good effect. In this paper we aim to use a tent map to encrypt the binary logo to achieve a like-noise signal. This approach makes extraction of the watermark signal by potential attacker very hard. Embedding locations are selected based on certain principles. Experimental ...

In this paper, we propose a new approach for optimization in audio watermarking using artificial intelligent technique. The watermarks are embedded into the low frequency coefficients in discrete multiwavelet transform domain. The embedding technique is based on quantization process which does not require the original audio signal in the watermark extraction. We have developed an optimization t...
متن کاملWatermark Bit Rate in Diverse Signal Domains
A study of the obtainable watermark data rate for information hiding algorithms is presented in this paper. As the perceptual entropy for wideband monophonic audio signals is in the range of four to five bits per sample, a significant amount of additional information can be inserted into signal without causing any perceptual distortion. Experimental results showed that transform domain watermar...
