WebMay 21, 2024 · Among them, optical encryption exploits abundant degrees of freedom (DOFs) of light (e.g., amplitude, phase, polarization, wavelength, and orbital angular momentum) to encode and decode target information, which opens a new door for information security communications and storage.
WebMay 13, 2024 · The dire need for network security was arisen to maintain the confidentiality and integrity of the data. So as to guard it against the un-authorised access. The steganography hides the traces of communication while cryptography uses encryption to make the message unable to understand. In this article, we will discuss about the major … WebAs an indirect imaging technique, computational ghost imaging (GI) obtains the object information by calculating the intensity correlation between a series of computer …
WebComputational ghost imaging (CGI), as a novel single-pixel imaging (SPI) technique, has a great potential and bright prospect in the field of optical information security owing to its encryption performances of data compression and real-value ciphertext. However, there are some vulnerabilities in CGI-based encryption technique, such as serious noise in the … 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.
