DWT Based Audio Watermarking Schemes : A Comparative Study

Lalitha N.V, Srinivasa Rao Ch, JayaSree P.V.Y
2016 International Journal on Cybernetics & Informatics  
The key idea of the basic algorithm is to segment the audio signal into two parts, one is for synchronization code insertion and other one is for watermark embedding.  ...  The main problem encountered during multimedia transmission is its protection against illegal distribution and copying. One of the possible solutions for this is digital watermarking.  ...  Extraction Algorithm The process of extraction is the exact reverse process of concealing process and the algorithm is given below: Step1: Apply DWT/DDDWT/DTDWT on the second part of attacked watermarked  ...

An Improved Non-Repudiate Scheme-Feature Marking Voice Signal Communication

Remya A R, A Sreekumar, Supriya M H, Tibin Thomas
2014 International Journal of Computer Network and Information Security  
Guaranteeing the ownership or copyright of digital communication is of extreme importance in this digital era.  ...  Thus, the digital watermark can be defined as a type of indicator secretly embedded in a noise tolerant signal such as image, audio or video data.  ...  So we need an efficient synchronization mechanism to detect and extract the exact replica of the embedded watermark from the signal.  ...

Audio identification based on spectral modeling of bark-bands energy and synchronization through onset detection

Mathieu Ramona, Geoffroy Peeters
2011 2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
The performance of these improvements is tested on a large set of real audio streams.  ...  In this paper, we present for the first time the fingerprint IRCAM system for audio identification in streams. The baseline system relies on a double-nested Short Time Fourier Transform.  ...  Section 5 will then assess the importance of synchronization through a study on the code robustness in subsection 5.1.  ...
