BER Performance of Audio Watermarking Using Spread Spectrum Technique

Sending the private data is always one of the fundamental problems in the communication systems. Therefore, information hiding was presented to protect the data. The evolutionary process has been continued until the watermarking as a new technique was generated to promote the copyright marking. Watermarking is trying to embed the private data such as text or numbers as a guest signal in the host signal with minimal effect on it. Audio watermarking was introduced as a one of watermarking techniques against the attackers and hackers that were raised on social networks.This paper presents an audio watermark algorithm with a blind detection which is based on a spread spectrum (SS) technique. A series of simulations were done on the proposed algorithm to estimate the Bit Error Rate (BER) for various values of signal-to-watermarking ratio (SWR) and bit rate. The simulationresults show that by decreasing the SWR ratio, the BER ratio is reduced to less than 10−3.
