Abstract :
Today, one of the most beneficial to human life is Internet. Information can be transmitted from far place through Internet. There is a problem usually faced when transmitting information, that is done by irresponsible people by editing or even changing the information on digital image. Steganography using Least Significant Bit method is used to hide an image in another image. Digital image bits that is wanted to be hidden will be substituted to the other media?s LSB. After analization and implementation using Visual Basic 6.0, the image with hidden message have to be similar to the original image to prevent people suspected that there are messages hidden on it. There is also password protection to maximize the security. The difference between the original image and the image with hidden message cannot be distinguish visually because the difference is only on the value of RGB bits of the images. Extracting the image will retrieve the hidden image. Therefore, the steganography criteria such as imperceptibility, fidelity and recovery can be fulfilled.
