KEY MODULATION REVERSIBLE IMAGE DATA HIDING OVER ENCRYPTED DOMAIN FOR SECURE IN FEATURE EXTRACTION

This work proposes a novel reversible picture information obnubilating (RIDH) conspire over scrambled area. [2] The information inserting is accomplished through an open key tweak instrument, in which access to the mystery encryption key is not required. At the decoder side, an intense two-class SVM classifier is intended to recognize encoded and non-scrambled picture patches, authorizing us to mutually disentangle the installed message and the unblemished picture flag. Contrasted and the condition of human expressions, the proposed approach gives higher implanting limit, and can perfectly recreate the unblemished picture and also the installed message. [1] Broad test comes about are given to approve the prevalent execution of our plan
