Information Hiding Algorithm - LSB Method for Extracting Concealed Data from Images with Code Implementation Details

Detailed Documentation

Information hiding algorithms are techniques designed to extract concealed data embedded within digital images. One widely adopted method is the Least Significant Bit (LSB) algorithm, which operates by inserting hidden information into the least significant bits of image pixels. The LSB algorithm functions by replacing the least significant bits of pixel values with the binary representation of the secret message, thereby achieving data concealment with minimal visual impact on the original image. Through extraction of these modified least significant bits from the image pixels, the hidden information can be successfully reconstructed. In typical implementations, the LSB extraction process involves: 1. Reading the image pixel array and converting RGB values to binary 2. Isolating the least significant bits from each color channel 3. Reassembling extracted bits into bytes representing the hidden data 4. Applying decoding protocols to reconstruct the original message This algorithm finds extensive applications in covert communication systems and data security domains, particularly for digital watermarking, steganography, and secure information transmission. The method's effectiveness stems from its minimal perceptual impact on image quality while maintaining reasonable payload capacity.
