| Abstract(in English) | Performance of steganography using discrete cosine transformed images depends on various factors and parameters. We investigate the relations among such parameters as signal to noise ratio of stego images, quantization step size, DCT coefficients into which messages are embedded, and properties of cover images. Results of our computer experiments show that the DCT coefficients F(u, v) with u+v=5 and 6 are good choices for embedding with respect to SNR and correct detection of message bits. |
