Separable Reversible Data Hiding in Encrypted Signals with Public Key Cryptography
Symmetry, 2018 We propose separable reversible data hiding in an encrypted signal with public key cryptography. In our separable framework, the image owner encrypts the original image by using a public key. On receipt of the encrypted signal, the data-hider embeds data
