sg-ntu-dr.10356-470122023-07-04T15:48:56Z Audio watermarking Htay Htay Yee. Foo Say Wei School of Electrical and Electronic Engineering DRNTU::Engineering::Computer science and engineering::Data::Data encryption 79 p. Digital watermarking is the method of embedding the information transparently into the host signal. For both applications and research field, digital audio watermarking becomes a special challenge as the sensitivity of human auditory system is exceptionally more than the sensitivity of human visual system. Watermark must be imperceptible and robustness to prevent illegal deduction. The project is proposed by employing a non-blind digital audio watermarking scheme using two channels time-frequency compression and expansion method. The original audio file is needed to decode the watermarked signal. The requirement of original audio data can be used to prove ownership. This project can provide high efficiency of watermark extraction against many different types of attacks acting upon the different kinds of audio signal. The main improvement of this project is supporting the 100% accuracy of watermark detection with the effect of combination of error-correcting codes which cannot be simply identified by the unauthorized person. Moreover, this report emphasizes on the best robustness against the power level 18 dB of addition of noise.
