Data security involves protecting digital information to prevent unauthorized access to computers, databases, and websites. Cryptography, encryption, and compression are key strategies for data protection. AES is a powerful cryptographic method. Confidentiality, authenticity, integrity, and non-repudiation are crucial for online communication. Steganography enhances message security across networks, using a photo as a cover material. The smart grid offers flexibility, reliability, and efficiency in power production and distribution. To protect privacy and confidentiality, greyscale cover images undergo discrete wavelet transformation (DWT) and a chaotic map is applied to the secret image
