Özet

Today, LSB (Least Significant Bit) method is still used in many corporate, commercial and personal steganography tools that hide messages in 24-bit, 8-bit color and gray-scale images. The reason why this method is often preferred is that it can be applied very easily and it allows a very large message storage capacity. However, Pixel Attack, which can be easily applied against the LSB method and visualizes the traces of the embedded message, maintains its place in the literature and in the steganalist's toolbox. In this study, instead of continuous message bit placement used in LSB method, DLSB (Distanced Least Significant Bit) Steganography, which is a basic method that uses proportional distance message bit placement and is resistant to Pixel Attack, is proposed.
