On reversible information hiding system [PDF]
, 2008 In this paper we consider the problem of reversible information hiding in the case when the attacker uses only discrete memoryless channels (DMC), the decoder knows only the class of channels, but not the DMC chosen by the attacker, the attacker knows ...

An Reversible Information Hiding Scheme Using Left-Right and Up-Down Chinese Character Representation [PDF]
, 2009 [[abstract]]Techniques for text data hiding are different from image data hiding, video data hiding and audio data hiding. To break through the difficulty of text data hiding, Sun, Lou and Huang proposed a novel Chinese text data hiding scheme called the
