Abstract
En 中文
One of the biggest challenges in data embedding is that the confidential data need to be in the 'transparency' after being embedded into the audio signal. Therefore, embedding methods must reduce the influence of embedded data onto the original audio signal. In this paper, the multiple bit marking layers (MBML) method has been proposed to fulfill this requirement. This method reuses the results from the previous embedding time (layer) as the input data to continue embedding it into audio signals (i.e. the next layer). The quality of the proposed method is evaluated through embedding error (EE), signal-to-noise ratio (SNR), embedded capacity (EC) and contribution error (CE). Experimental results have shown that the proposed method provides better quality of EE, and SNR than any other proposed embedding methods such as: LSB (Least Significant Bit), ELS (Embedding Large Sample.), BM (Bit Marking), and the BM/SW (Sliding Window) method with a single layer.
