碩士 === 國立中興大學 === 資訊科學與工程學系 === 104 === In recent years, with the popularization of Internet, using Internet to share multimedia information has become more convenient and fast, and lifted the restrictions of time and space. Therefore, information security and copyright protection have become important research topics. Currently the use of digital images as hidden information carrier has become one of the main data hiding techniques. The hidden data is embedded in some carrier image. There is almost no difference between embed image. In this thesis, we focus on improving reversible information hiding technology. The proposed scheme can achieve higher embedding capacity than other methods.
