Research enhances online security

January 21, 2014 by Keith Hautala

As the digital world becomes more and more integrated with day-to-day life, computer scientist Samson Cheung's research is helping to provide necessary safeguards, without sacrificing the benefits brought forth by new technologies.

Cheung, an associate professor in the Department of Electrical and Computer Engineering at the University of Kentucky, focuses on developing efficient, robust and secure systems to analyze, process and communicate information. Cheung and his research group are working on visual privacy protection, secure computation, multimedia content management and networking.
