Detecting Hidden Images and Text

In an age of digital communication, in fact exclusion and secretly altering information is already one of the most used techniques. It is both a form of creativity and a crime. Hidden images and texts–produced by such techniques as Steganography, Watermarking and Cryptic encoding–force users to look at the surface, but be concerned what lies beneath. For instance, This paper explores how this hidden content is created, what motivations might drive its use, and evolving techniques to detect it. It draws on both technical and literary viewpoints, and focuses precisely upon that contradiction which exists between secrecy and discovery in the digital era.
