Abstract :
Today, data security in digital environment (such as text, image and video files) is revealed by development technology. Steganography and Cryptology are very important to save and hide data. Cryptology saves the message contents and Steganography hides the message presence. In this study, an application of fuzzy logic (FL)-based image Steganography was performed. First, the hidden messages were encrypted by XOR (eXclusive Or) algorithm. Second, FL algorithm was used to select the least significant bits (LSB) of the image pixels. Then, the LSBs of selected image pixels were replaced with the bits of the hidden messages. The method of LSB was improved as robustly and safely against steg-analysis by the FL-based LSB algorithm.
