Venue:基础教学楼A320
Abstract:
Secure digital imaging is an important research area combining methods and techniques coming from cryptography and image processing. Visual cryptography and in general secret image sharing techniques enable distributing sensitive visual materials to involved participants through public communication channels, as the generated secure images do not reveal any information if they are not combined in the prescribed way. In visual cryptography, the decoding process is performed directly by the human eyes, while in general, the secret image sharing needs some processing to reconstruct the secret image. In this talk, I will describethe latest techniques, algorithms, and solutions for visual cryptography and secret image sharing.
