Data hiding is the process of incorporating information into a source of data without modifying its perceptual quality. Steganography is the art and science of creating concealed communications by blending information with other information so that only the sender and recipient of the message are aware of its presence. Here, the Least Significant Bit (LSB) algorithm is used to implement text steganography, image steganography, audio steganography by LSB Modification using Advanced Encryption Standards, and video steganography by KSA and PRGA algorithms. The secret message is first encrypted using the Cryptography RC4 algorithm before being embedded in the image, text, audio, and video files. Using the proper decoding technique, one can extract the personal text from the stego file and decrypt the hidden message. Steganography uses sophisticated software to conceal the data from a third party. Steganography and cryptography can be used together to securely hide the secret message.
