Data hiding mechanism based on encrypted image in a discrete wavelet zone of a carrier image

Abstract

Now a day's to keep up secrecy and confidentiality of an information could be a vivacious field with 2 totally different approaches being followed, the primary being encrypting the pictures through cryptography algorithms victimization keys, the opposite approach involves concealing knowledge victimization data concealing algorithmic program to keep up the pictures secrecy.A content owner use cryptography key to perform the cryptography of original pictures, and employing a information hiding key a data hider will plant further data into the encrypted image although he doesn't recognize the first content, because the encrypted image contains some further information, with the assistance of cryptography key a receiver 1 si decipher it then extract the embedded information and recover the first image in line with the data-hiding key.
