In this paper, our proposed scheme using two steganography images. Unlike other data hiding schemes, this scheme studies the characteristics of the Tangram puzzle model and the secret message bytes that make up the eight binary bits that are hidden into the two graphs. Key matrix M *, horizontal and vertical coordinate range from 0 to 255, and the pixel pairs in the cover image are used to help hide the secret message bytes in our scenario. The paired pixel points into single and double number hidden in two figures. Experiments show that the program can hide relatively more pixels in a cover image with less losing image quality.
