초록
Steganography is hiding messages in cover materials like image, audio, etc. The previous studies are limited in the shifting problem of the histogram and capacity. This paper proposes a new technology which overcomes these two problems. Our new technology uses two colors as a pair and chooses either changing to its partner or remaining as they are according as each hiding bit. As a result, we show that the result of this technology shows that the hiding capacity is higher than other methods.
