| Research Abstract |
A technique for reversible information hiding that is based on compression for binary images was proposed and a method for steganalysis to evaluate information hiding techniques were studied. Three information-hiding techniques for QR codes were investigated. One of them is based on the proposed reversible information hiding, and other two methods are based that message we want to embed is put after the terminate code of QR code, and Wet paper code is used to represent the message. In addition, the secure release system of examination score which is based on RSA public key crypto system and information hiding for QR code was studied.
