Dr. Sen-ching (Samson) Cheung is an associate professor in the Department of Electrical and Computer Engineering. He and his research group are working on visual privacy protection, secure computation, multimedia content management and networking. Dr. Cheung is researching 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. Other types of multimedia data from audio recordings to medical images can benefit from Dr. Cheung’s research on secure computation on encrypted data, where valuable information can be extracted without jeopardizing the privacy of individuals. 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.
