Huang Fang-yuan · Journal of Guizhou University · 2008
With the popularization of Internet and increase of bandwidth,the transmission of multimedia information such as image and video frequency become increasingly convenient and fast.Long-distance medical treatment and office automation can be realized by Internet,too.Besides,many important image information can be spread through Internet.For example,patients' cases,drawing design,military information.But these information must be encrypted.Image Scrambling can be regarded as one of the encryption techniques.In this pager,we introduced Arnold transforming,then discussed image scrambling based on Arnold transforming and it's period.At last we implemented the arithmetic by matlab 7.0.
