Congratulations to Vis Center Faculty member, Dr. Sen-ching (Samson) Cheung on promotion to associate professor with tenure in the Department of Electrical and Computer Engineering. He and his research group work on visual privacy protection, secure computation, multimedia content management and networking.
Dr. Cheung’s current research focuses on ways to protect the privacy of innocent passers-by and authorized people in surveillance video by accurately identifying their presence and completely erasing their images. Using a novel high-capacity steganographic scheme, privacy information is hidden in the modified video and can be retrieved with proper authorization. As the cyber world becomes more and more integrated with day-to-day life, Dr. Cheung’s research provides the necessary safeguards without compromising the benefits brought forth by the new technologies.
