摘　　要：信息隐藏技术在知识产权保护和隐蔽通信等方面发挥着重要的作用。而目前存在的基于文本格式的信息隐藏技术在应用方面存在一定的局限性。将字符转换成Unicode编码的二进制形式,通过对载体字符与隐藏字符的二进制编码的运算提出了一种文本零水印的信息隐藏方法。该方法不限文本格式,解密时的标记文本与原文件分开。与同类隐藏方法相比具有较大的隐藏容量,算法的安全性、隐蔽性与鲁棒性较好。该方法将具有很广泛的应用前景。Information hiding technology has a wide range of application and research prospects in covert communication, intellectual property protection and so on. But there are still some limitations in existing information hiding methods. Convert character into Unicode, and then transform Unicode to binary form. It presents a zero-watermark method of information hiding of text through the operation between the binary codes of vector characters and hidden characters. This algorithm has nothing to do with the text format, and compared with some other hidden algorithm, it has much more capacity, better invisibility and better robustness. This method will have broad application prospect.
