Abstract
Steganography is a method used to enhance the security of messages across networks, derived from the Greek words steganos (secret) and graphic (writing). Researchers have explored image steganography, a method that uses a photo as a cover material. The modern energy grid, known as the smart grid, offers flexibility, dependability, and efficiency in power production and distribution. To protect privacy and confidentiality, a greyscale cover picture is subjected to discrete wavelet transformation (DWT), while a chaotic map is applied to the secret image. This method offers more security and can shield communication from stegoimage attacks. Additionally, a novel approach to disguise an image is presented to combat cryptography and steganography algorithms attacks.
