摘要：The reversible data hiding techniques, which areused to improve the distortion in images. We have proposed asecure RDH method, Based on Histogram Modification andRandom Scramble Transform. This Paper consists differentphases for embedding of data, encryption of image, and dataextraction/image-recovery. In first phase, the owner getscontent’s histogram by the inverse s-order technique. Afterthat hides the additional data into the image and thenencrypts the image with the help of encryption key. At thereceiver end the receiver does not have knowledge about theoriginal content of encrypted image associated with additionaldata. A receiver gets only the contents of the image afterdecryption according encryption key, and then extract theembedded data and gets the original image and embeddeddata separately. In the scheme, the data extraction fromdecryption is non-separable. The proposed technique wastested for different hiding capacity and the consequencesshowed that it has excellent output quality. In the tests we getthe proposed algorithm to support high capacity rate reachup to approx 0.2 bits per pixel and that is form above 1/4(25%) from the size of the input image cover file at PSNRabove 55 dB for the output signal.
