Protecting LSB method of data steganography is a vital issue. In this paper research a secure LSB method will be introduced. The method will use a private key to divide a covering image into block and a secret block will be selected to apply message hiding and message extracting. The extracted message will be very sensitive the selected block size and the selected block number. The proposed method will simplify the hiding and extraction functions by using patch method, this simplification will increase the method efficiency. The proposed method will be tested for sensitivity, several images and several messages will be selected and the quality of the stego images will be examined.
