Steganography explained and how to protect against it

Webcryptography, the secret information is altered in a way that it cannot be readable to eavesdroppers, but with steganography, the existence of the secret information is completely concealed from unauthorized persons [4-5]. The value of the confidential data obtained from a system is the most important thing to the attacker [6,7]. 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. trusted property management company
