Abstract

The discrete cosine transform (DCT) has performance close to Karhunen-Loeve Transform (K-L Transform). In this paper, DCT is used for speech information hiding. Secret information is embedded by changing the parameters in DCT domain and extracted by statistical method at the receiving end. Results of analysis and experiments indicate that this algorithm can embed as well as extract secret information effectively. In the end, we successfully realize the algorithm in FPGA using Verilog language.
