Visual cryptography is a cryptographic technique which allows visual information (pictures, text, etc.) to be encrypted in such a way that the decrypted information appears as a visual image. One of the best-known techniques has been credited to Moni Naor and Adi Shamir , who developed it in 1994. [ 1 ]
In order to use chaos theory efficiently in cryptography, the chaotic maps are implemented such that the entropy generated by the map can produce required Confusion and diffusion. Properties in chaotic systems and cryptographic primitives share unique characteristics that allow for the chaotic systems to be applied to cryptography. [ 7 ]
Le Freeport, formerly known as Singapore Freeport, is a high-security storage and display facility in Singapore. [1] A majority stake is held by Natural Le Coultre S.A. of art dealer and shipper Yves Bouvier. [2] Opened near Singapore Changi Airport in May 2010, the facility is modelled after similar institutions in Geneva and Luxembourg.

Secret sharing was invented independently by Adi Shamir [1] and George Blakley [2] in 1979. A demonstration of visual cryptography: when two same-sized binary images of apparently random black-and-white pixels are superimposed, the Wikipedia logo appears
Nancy Pelosi’s husband dumped 2,000 Visa (V) shares in July — just weeks before the payments giant was sued by the U.S. Department of Justice (DOJ) for monopolizing the debit markets.
visual cryptography stenography: Image title: Creation of masks to let overlaying transparencies A and B printed with black rectangles reveal a secret image by CMG Lee. Each corresponding pixel in the component images is randomly rotated to avoid orientation leaking information about the secret image. Width: 100%: Height: 100%
