Data Hiding in Encrypted Images by using Huffman coding algorithm
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 8
Abstract
It is used for privacy, security, and protection. As the entropy of encrypted images is maximized, it is difficult to losslessly vacate room after encryption using the existing methods. In the proposed work, security and authentication can be ensured using the Huffman Coding Algorithm In this proposed system the original image is encrypted using encryption key and the data is embedded using data hiding key then the image & data is decrypted in the receiver side using respective keys. we propose to consider the patch-level sparse representation when hiding the secret data. a large vacated room can be achieved, and thus the data hider can embed more secret messages in the encrypted image.
