Optical ghost cryptography and steganography
WebSteganography is the technique of hiding secret data within an ordinary, non-secret, file or message in order to avoid detection; the secret data is then extracted at its destination. The use of steganography can be combined with encryption as an extra step for hiding or protecting data. WebThe theoretical description and the experimental results show the ability the security systems exhibits to protect and recover the information by optical means, including the tolerance to data loss during transmission, as well as the vulnerability to chosen-cyphertext attacks of optical encryption schemes based on double random phase keys. In this …

WebJun 15, 2024 · Steganography works by replacing bits of unused data in regular computer files with bits of your own data. In this case, the data will be the plain text, and the unused data is the least significant bits (LSBs) in the image pixels. In this article, we'll show you how to hide encrypted information within an image file (JPG,PNG etc) in C#. 1.
