A huge number of messages circulate through social media, and many of these messages are confidential or carry personal information, which requires protection from intruders. The least significant bit method of data steganography is effective in masking messages, but it is not secure. In this research paper we will present a way to raise the security of the method of hiding messages without affecting the effectiveness of the method by keeping the MSE values low and PSNR values high. The proposed method will base on extracting a secret block from the image, this block will be used as a covering media to hold the secret message, after inserting the secret message the block will be returned back to the covering image.
