A Novel Technique in Cryptography for Data Hiding in Digital Images

Visual cryptography, an emerging technology used in the purpose of data hiding and other specific purposes, uses the characteristics of normal encryption 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 the authors can the technique of cryptography.
