Today steganography has attracted the attention of many researchers. In this paper, we propose a new steganography method for secure Data communication on half tone pictures. Using the halftone pictures improve the security and capacity. In this method, the complexity of every pixel in picture is computed, then a neibourhood is defined to compute the complexity of every pixel, and then the complexity of every pixel is computed in the neibourhood. Placing data in the monotonous areas of halftone can explain the presence of hidden data. A method has been represented that surveys the position of every pixel neibouring others and prevents including in monotonous areas. If that was a complicated one, steganography bit after stonehalf will be hidden after scrolling the whole, the process of spreading error will be done. Performing the suggested method improves the quality of placing picture and increases its security.
