Abstract :
The paper puts forward a novel steganographic method based on the JPEG digital images. Instead of dividing cover-image into 8×8 blocks, non-overlapping blocks of 16×16 pixels is used. With our proposed quantization table, The DCT coefficients are quantized and embedded the secret messages. The experiment results show that our method has the larger steganography capacity and better stego-image quality than the other methods.
