Audio Watermarking for Medical Applications based on Hybrid Transform - Softcover

Inhaltsangabe

Watermarking is a technique which is used for protecting information like images, videos and audio as it provides copyrights and ownership. Audio watermarking is more challenging than image watermarking due to the dynamic supremacy of hearing capacity over the visual field. This thesis attempts to produce a new algorithm for audio watermarking technique based on hybrid transform (discrete wavelet transform and radon transform). This study considers two types of encryption: linear feedback shift register sequence and Gold sequence. The performance of the proposed method has been studied by comparing the set of features to make sure of the efficiency of this system. Because of the speed that we need in the work, study and evaluate the steps method presented has been using programming language MATLAB.
