%X A New Steganographic Algorithm for palette-based images was proposed.According to the theory that sensitivity of different color was different for cone cell of human eye,the palette was sorted by RGB,the set of the closest colors and color isolated were calculated,and LSB of pixel index which parity was correspond to bit embedded was replaced in the set of closest colors,it could arrive at the goal of hiding information in the images.Besides,the security and capacity of this algorithm were analyzed by comparing with EZ Stego.And experiment is done to show the effect in Gif image.
