WitrynaImage steganography relies on altering a picture's pixel values such that the secret information is hidden inside the image but the naked eye cannot tell the difference. To do this, one may use methods like the LSB algorithm, which works by shifting the image's least significant bits. In the suggested approach, data to be conveyed through ...
