LSB Image Watermarking - Adding Watermarks

LSB (Least Significant Bit) image watermarking involves embedding secret information into the lowest bit positions of carrier image pixel values, which are also referred to as the least significant bits. Modifying these bits has minimal impact on image quality since they contribute least to the visual appearance. This method effectively hides secret information while maintaining image fidelity and enhancing information security. The LSB embedding technique cleverly integrates secret data into images, making the information virtually imperceptible to the human eye. This technology finds extensive applications in digital watermarking, steganography, and information hiding systems. Through LSB embedding, various types of secret information including text, graphics, and audio can be concealed within images. The primary advantages of this approach include straightforward implementation using bitwise operations (such as bit shifting and masking), no requirement for additional encryption steps, and negligible impact on the visual quality of carrier images. Typical implementation involves iterating through image pixels, converting secret data to binary format, and replacing the LSBs of each pixel byte with sequential bits from the secret message.
