Steganography using AES and Edge Image

Abstract

Steganography is the art of hiding messages in an image. This is a great way to send a secret message without drawing attention to it. Many technologies have been developed to ensure data security, and cryptography is considered one of the most important sciences used since the dawn of humanity. Using this proposed technique, we take the input text(128-bit) with key(128-bit), encrypt it using AES technology, and then hide out text(128-bit) inside the edges of the image free size. This is done by extracting the edges of the image and combining them with the ciphertext to make them disappear completely. Text data security is a good thing with this proposed new technology. It is also easy to extract text from the edges of the image and re-decode it. The resulting image is the same as the selected image, clear with raised edges, with text disappearing within the edges of the image indistinguishable from the naked eye. Therefore, this proposed method is considered the safest in hiding data inside the image.
