Abstract: Information and communication technology is growing, so, security enhancement will also be more important. One of the factors is the level of security in hiding data/information. It is known that steganography method is used in to hide an information in digital media. Digital media that is used in steganography are Text, Picture, Audio and Video. In this study, we discuss one of the techniques of steganography on the text media. This technique is a Word-shift technique where the secret message is converted into a series of bits embedding process into the document file by shifting spaces between words. The process of shifting to the right between words occurs when the input bit is “1”. If the input bit is “0” then between the words will shift to the left. After the secret message is inserted then it will be extracted from the document in the printing and scanning process. In the process of extracting this secret message, we use the centroid method to detect the center of the image and then get the secret message that has been inserted.
