A Novel Technique in Cryptography for Data Hiding i n Digital Images
Journal Title: INTERNATIONAL JOURNAL OF COMPUTER TRENDS & TECHNOLOGY - Year 2013, Vol 6, Issue 4
Abstract
Visual cryptography [1],[6] an emerging technology used in the purpose of data hiding and other specific purposes, uses the characteristics of normal encryption[13] and decryption levels of many digital images. Generally, technology that uses images needs neither cryptography knowledge nor complex computation. For ensured concerns, it also assures that cyberpunks cannot perceive any idea about the image in which the information is hidden. The use of cryptography mainly targets binary images because by using the basic level of image i.e., using binary image (black & white) only we can the technique of cryptography; This piece of cryptogram proposes three sub sects for visual cryptography(VC) based on binary i.e., black and white images of gray-level and color images. There are many methods such as halftone, Visual Cryptography, etc. Many of techniques use noise-like random pixels on shares to hide secret images
