讲座摘要：
Audiences will learn how to secure multimedia (e.g., digital images) by secret sharing. Secure digital imaging is an important research area combining methods and techniques coming from cryptography and image processing. Secret image sharing and visual cryptography 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. There are high similarities and tight relations between SIS Scheme and VCS. In fact, these two models are only different ways of looking at the same problem. Thus, the same research issues can be studied by using these two approaches, respectively, and still have contributions. Moreover, both approaches can be properly combined to develop their specialties and simultaneously avoid the disadvantages. This lecture covers the latest techniques, algorithms, solutions and application for secret image sharing.
