Digital steganography using computer can use a variety of digital file, digital image file is one of them. With the infomation being hidden inside the image-carrier, the others will not aware about the hidden information. Application created using C# programming leanguage and the steganoraphy method using Least Significant Bit Insertion (LSBI). Microsoft Visual Studio used as Integrated Development Environtment (IDE) to code and design the user interface. Software develpment model using Extreme Programming, and the testing using black box method. Application designed to hide text or image inside an image-carrier and the hidden text or image can be recovered.
