碩士 === 國立中興大學 === 通訊工程研究所 === 101 === In this study, we make use of Linear Block Codes for Data Hiding to increase the embedding efficiency and decrease the information distortion. However, the higher the dimension of codes is, the more complicated it is to decode . So the main purpose of our study is to propose an easy , quality-maintaining, way for embedding binary information with a max capacity . We can embed information by Product Code which is also a sort of linear block code. It is character by that we can choice Component Code to change the characteristic of code such as code rate and correcting ability. According to its decoding, we propose some modified decoding algorithms to lower the decoding error rate and higher the efficiency. After then, we compare the embedding efficiency and complexity of the algorithms which we proposed.
