An Introduction to Visual Cryptography for Binary Images Okechukwu Ikoro 7061018 INSE 6110 Abstract Visual Cryptography is a type of cryptographic scheme used to hide a secret image in shadow images called shares or layers such that it can’t be decrypted using the human visual system unless certain qualified subsets of the shares are used. The secret image is encoded without the use of any cryptographic computations. The topic of visual cryptography is a broad one with many fields however in this
1.1Overview VISUAL cryptography (VC) is a branch of secret sharing data. In the VC scheme, a secret image is encoded into transparencies, and the content of each transparency is noise-like so that the secret information cannot be retrieved from any one transparency via human visual observation or signal analysis techniques. In general, a -threshold VC scheme has the following properties: The stacking of any out of those VC generated transparencies can reveal the secret by visual perception, but the

Introduction Cryptography may be defined as the process of enciphering data using mathematical model or algorithm, before transmission and then deciphering the obtained data from channel using a model which works in reverse manner to the encipher thereby allowing a person to transmit information across networks so that it

communication method used to hide secret data in some digital media such as images, audio etc. Cryptography and watermarking are other similar techniques. Data is secured using these methods, but the fact that data is present somewhere gives us a specific target, whereas sole purpose of steganography is that none must know there is some hidden data in the file. So, steganography easily has upper hand over cryptography and watermarking. Steganography can use almost all kinds of media present over internet

The National Institute of Standards and Technology (NIST) gave meaning of cloud computing, which demonstrates the vast majority of the key components of cloud computing [1]: "Cloud computing is a model for enabling convenient, on demand network access to a shared pool of configurable computing resources (e.g., networks,
CISSP Exam Notes - Physical Security 1 CISSP Exam Notes - Physical Security 1. Introduction 1.1 Physical security addresses the physical protection of the resources of an organization, which include people, data, facilities, equipment, systems, etc. It concerns with people safety, how people can physically enter an environment and how the environmental issues affect equipment and systems. People safety always takes precedence over the other security factors. 1.2 Physical security is
