Robust Bit Modification based Audio Watermarking

Abstract

In this paper watermark is embedded into audio signal by modifying the samples data with the watermark key. An unvoiced and voiced data with payload equal to 16000 Hz is used for the simulation. Under different noise adding conditions the performance of the system is evaluated. Also in this paper performance of the algorithm is analyzed by varying the bit modification location of the 8 bit sample from LSB to MSB. MATLAB is used for the simulation purpose.
