Abstract: Steganography is the art of concealing the communication existence by hiding the secret message in cover media. The major goals of steganography are undetectability, robustness and embedding capacity. This paper aims to study image steganography using Canny Magic LSB Substitution Method (CM-LSB-SM) for hiding secret bits in Least Significant Bits (LSBs) (1-LSB and 2-LSB). Firstly, cover image is separated into three components (Red-Green-Blue) images and is detected the edge pixels using Canny Edge Detection. Then, the secret message is embedded in the location of Magic Matrix sequence of the three edge images by applying LSB Substitution method. Their performance is measured using PSNR (Peak Signal to Noise Ratio), MSE (Mean Square Error), EC (Embedding Capacity) and Histogram. The findings indicate that the CM-LSB-SM (2-2-2) method supplies a relatively high embedding capacity in the higher edge pixel image.
