Steganography, derived from Greek, literally means "covered writing". It includes a vast array of secret communications methods that conceal the message's very existence. These methods include invisible inks, microdots, character arrangement, digital signatures, covert channels, and spread spectrum communications. Pixel Value Differencing (PVD)[8] was proposed for gray scale images where two consecutive pixel pairs are formed and embedding capacity is decided based on difference in their values… CONTINUE READING
