摘要

提出了一种将秘密二值图像隐藏在噪声图像后进行秘密通信的新方法，该方法具有秘密认证的能力。要传输的秘密图像在具有给定密钥的发送站点被转换为随机噪声图像，目的是既掩盖秘密又欺骗非法拦截者。认证位也被嵌入到噪声图像中。在接收端，使用相同的密钥从噪声图像中恢复秘密图像，并通过检查认证位的存在来验证。实验结果表明，该方法在实际应用中是可行的。

Hiding binary images behind noise with authentication capability: a new approach to covert communication

A new approach to hiding secret binary images behind noise images for covert communication with a capability of secret authentication is proposed. A secret image to be transmitted is transformed into a random noise image at a sender site with a given key, with the aim of both covering the secret and cheating illicit interceptors. Authentication bits are also embedded imperceptibly in the noise image. At the receiver site, the secret image is recovered from the noise image with the same key and verified by checking the existence of the authentication bits. Experimental results show the feasibility of the approach for real applications.
