Abstract:
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 Kronecker 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 information 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.
