摘　　要：针对当前隐私信息隐藏方法无法满足隐私信息隐藏实时性、高隐蔽性且嵌入容量大等通信需求,提出基于位平面压缩的多频无线网络通信隐私信息实时隐藏方法。以位压缩编码形式将隐私信息低位平面信息保留在压缩后的高位平面中。运用比特替换形式在低位平面嵌入密文,在嵌入域内按位重组隐私信息。接收端在密文域中采用模乘法逆元提取出密文,对其直接解密无损恢复出原始隐私信息。实验结果表明,所提方法能够有效避免隐私信息彼此覆盖,实现隐私信息的实时传输,且具有较高的嵌入容量。A real-time hiding method of multi-frequency wireless network communication privacy information based on bit plane compression was proposed. This method used bit-compression coding to preserve the low bit plane information of private information in the compressed high bit plane. Then, our method used the form of bit replacement to embed the cipher text in low bit plane and recombined privacy information bit by bit in the embedded domain. Meanwhile, the receiver used the modular multiplication inverse to extract the cipher text in cipher text domain and decrypted it directly. Thus, we restored original private information non-destructively. From simulation results, we can see that the proposed method can effectively avoid the privacy information covering each other, which has a high embedded capacity. Meanwhile, the real-time transmission of private information is achieved.
