Kok Sheik is an Associate Professor attached to the School of Information Technology at Monash University Malaysia. He received the B.S. and M.S. degrees in both Computer Science and Mathematics from Utah State University, USA, in 2002 and 2005, respectively. In 2009, he received the Doctor of Engineering degree from Shinshu University, Japan, under the scholarship of Monbukagakusho. He was with Multimedia University from 2009 to 2010, and University of Malaya from 2010 to 2016. His research interests include multimedia signal processing, data hiding, multimedia perceptual encryption, joint encryption and data-hiding method, as well as their applications. He is a senior member of IEEE and a member of APSIPA.

In 2015, his student’s thesis received the Best Ph.D thesis award from the IEEE Signal Processing Society, Malaysia Section. Dr. Wong served as an associate editor for the Malaysian Journal of Computer Science from 2013 to 2017. Currently, he serves as an associate editor of the IIEEJ Transactions on Image Electronics and Visual Computing.
