abstract: Embedding data in audio signals is a technique to hide a certain amount of information in the digital audio signal to preserve confidentiality and authenticate information. The bit replacing methods are now mainly used in the techniques of data embedding in the audio signal. Although the capacity of data embedding is large, but embedding error (EE) is high, thus reducing the possibility of transparence of embedded signal. In this paper, we propose a novel method of bit marking (BM) to embed data into the audio signals. To reduce the embedding error and increase signal- to-noise ratio (SNR), we first conducted comparing each segment of data to the bit segments in the audio samples, then find out the bits of audio signals which coincide with embedded data. After that, we use the low- significant bit of audio samples to mark the positions of the bit segments found. The number of marking bits is reduced by the minimization algorithm, and optimization of the parameters of the system. The experiment results show that the quality of the proposed system is better than the least significant bit (LSB) and the embedding large sample (ELS) methods. Therefore, the security of the embedded data is also significantly improved.
