摘　　要：提出了一种基于规范类正交矩阵的信息隐藏及提取电路的设计与FPGA实现.利用基于构造矩阵的查找算法和克罗内克积扩展,实现规范类正交矩阵快速构造;隐秘数据经过规范类正交矩阵编码后,具备线性性质,修正相关检测后的判决输入数据,实现隐秘数据的提取;鉴于多媒体数据处理的速度和嵌入隐秘信息的效率要求,采取了使用FPGA实现基于规范类正交矩阵的信息隐藏及提取电路的设计方案.结果表明,该装置电路结构简单,能够满足多媒体数据实时处理的要求;在发送端,隐秘信息被快速嵌入到载体数据流中;在接收端,通过生成相同的规范类正交矩阵,分别将载体信息和隐藏信息准确地提取出来.This paper presents information hide based on specification class orthogonal matrix and extraction circuit design and FPGA implementation. It uses the search algorithm based on the structural matrix and the Kroneeker product expansion to realize the rapid construction of the normal similar-orthogonal matrix. The hidden data after the normal similar-orthogonal matrix coding, has a linear nature. The judgement after the revised relevant detections is taken as input data to realize the extraction of the hidden data. In view of multimedia data processing speed and efficiency of embedding secret information requirements, FPGA is used to realize a design program of hidding information based on the normal similar-orthogonal matrix, and extracting circuits. The results show that the apparatus circuit configuration is simple, and can meet the requirements of real-time processing of the multimedia data. And that at the transmitting end, the secret in- formation is embedded fast to the carrier in the data stream by generating the same canonical class orthogonal matrices, and that at the receiving end, the carrier information and hidden information are accurately extracted.
