Webhidden image. To prevent the steganography breaking and increase the security of the encoding process, we further introduce the widely-used RSA cryptography into our optical ghost steganography. Our simulation and proof-of-principle experiment pave a way to the application of GI into the ﬁelds of cryptography and steganography. WebJul 6, 2024 · The purpose of steganography is to conceal and deceive. It is a form of covert communication and can involve the use of any medium to hide messages. It’s not a form of cryptography, because it doesn’t involve scrambling data or using a key. Instead, it is a form of data hiding and can be executed in clever ways.
