AN INFORMATION HIDING USING DATAGLYPH FOR AUDIO WATERMARKING

摘要：

Text watermarking using text lines has a limited capacity problem in hiding data.Therefore, a technique for high capacity data hiding in audio watermarking is presented.The objective is to maximize the payload while keeping robustness and simplicity.In this paper, we propose a new method for data hiding by applying the DataGlyph technique. First, the encoded message is transformed to a DataGlyph as a 2D barcode.Next, the DataGlyph is prepared to be watermarked via a robust audio watermarking scheme based on the DWT-GA.Both DWT-GA are the essential mathematical tools for this scheme. After applying the DWT to the given audio signal, we map the DWT coefficients and apply the GA.We search for the optimal position of audio watermarking by using the GA.Experimental results have shown that this watermarking method performs well in both security and robustness to many digital signal processing methods, such as filtering, cropping, mp3 and random noise.
