摘要
使用Unicode的主要意义在于可以满足跨平台、跨语言的文本处理和转换。为了提高文本信息在传输中的安全,可采用文本的Unicode编码嵌入图像并进行图像加密的方法,由于文本信息与图像信息在计算机中的存储表达均采用二进制,将文本信息嵌入无规则的图像中,再对图像进行读取,在未知文本位置及编码结构的情况下是难以与像素信息加以区分的。实践证明使用Logistic混沌理论进行图像加密可以达到比较理想的效果,应用图像加密手段加密文本信息可以有效提高信息的安全性。
The use of Unicode means that the cross-platform and cross-language text processing and con- version could be realized. In order to improve the text information security in the transmission, text enco- ding of Unicode embedded image and image encryption may be adopted. For the text information and the image information in binary expression are stored in the computer, text information is embedded into the ir- regular image, and the reading of image information in the case of unknown position of text and coding structure would become difficult in distinguishing text information from pixel information. Practice proves that with Logistic chaos theory for image encryption, an ideal result could be achieved, and the application of image encryption for text information encryption can effectively improve the information security.
