Hiding Information in Digital Images Using LSB Steganography Technique

The highest way to protect data from intruder and unauthorized persons has become a major issue. This matter led the development of many techniques for security, such as Steganography, Cryptography, Watermarking disguise data. paper proposes an image steganography method using Least Significant Bits (LSB) technique XOR operator secret key, through which key is transformed into one-dimensional bit stream array, then these bits are XORed with image. Multiple experiments have been performed embed color grayscale images inside cover media. In this work, LSB ideal in two ways: firstly, only least significant one-bit (1bit) each byte will store embedded data, named (1-LSB). Secondly, four right half-byte (4 bits) (4-LSB). Subjective objective analyzes were process. subjective analysis responsible both HVS histogram, whereas involved PSNR MSE metrics.
