A Hybrid Reversible Image Data Hiding Scheme With Symmetric Key Cryptography

This paper proposes a hybrid reversible image data hiding technique (RIDH), which is used to reconstruct an original image upon the extraction of the embedded data. Encryption and data hiding are two effective means of data protection. Encryption converts an original image into unreadable ciphertext and data hiding is used to embed additional data into image. Previous methods used secrete data hiding key for data hiding, now this paper proposes both encryption and decryption with rivest cipher 4 (RC4) and data hiding with advanced encryption standard (AES) without secrete data hiding key. Support vector machines (SVM) classifier is used to separate encrypted and non-encrypted blocks to reconstruct original image from embedded image by using feature calculation of each and every block. Evantually a trail results are given to approve the predominant execution of our method.
