New Region Incrementing Visual Cryptography Scheme
Recently, Wang introduced a novel (2, n) region incrementing visual cryptography scheme (RIVCS), which can gradually reconstruct visual secrets with multiple secrecy levels in a single image. A secret image is divided into multiple regions, where each region has a certain level of secrecy. Any t shadow images, where 2tn, can be used to reveal (t1) levels of secrets. However, in Wang’s scheme...
متن کاملConstruction of General (k, n) Probabilistic Visual Cryptography Scheme
⎯Visual cryptography scheme (VCS) is a secure method that encrypts a secret image by subdividing it into shadow images. Due to the nature of encryption VCS is categorized into two types: the deterministic VCS (DVCS) and the probabilistic VCS (PVCS). For the DVCS, we use m (known as the pixel expansion) subpixels to represent a secret pixel. The PVCS uses only one subpixel to represent a secret ...
متن کاملk out of n NonBinary Audio Cryptography Using Polynomial Interpolation
Audio cryptography is same like a visual cryptography. A plain data (audio file) is split into two or more shares. Each single share does not convey any meaning but when shares are combined together they will reveal the original data. In Audio cryptography the "plaintext" is an audio File. k out of n Nonbinary Audio Cryptography scheme is a special type of secret sharing scheme which is more se...
متن کاملk-n Secret Sharing Visual Cryptography Scheme on Color Image using Random Sequence
Visual cryptography is a special type of encryption technique where visual information (Image, Text etc) gets encrypted in such a way that decryption can be performed by Human Visual System with a computation free decryption process. The beauty of the visual secret sharing scheme is in its decryption process where without any complex cryptographic computation encrypted data is decrypted using H...
متن کاملNumber theory based { k , n } Visual Cryptography Scheme For Color Images
An efficient and secure visual secret sharing scheme suitable for transmission of color images is introduced and discussed in this paper. The scheme employs number theory concepts and the pixel level representation of the color image to derive reciprocal encryption and decryption procedures. Using the input color image, the scheme generates n shares which are then distributed to participants. A...
