This paper mainly throws light on embedding methods in encrypted images using RDH Algorithm. Because more attention paid to this technique which maintains lossless original cover of image after retrieving. This overcomes the previous method of vacating room from encrypted images. Here the novel method of reserving room before encryption is taken into consideration. We intended to study the two different data hiding methods. LSB replacement data hiding and another using PN sequence generation
