【摘要】 文本信息隐藏是版权维护的一种重要手段,针对现有算法存在信息隐藏量不足、鲁棒性不高及多数仅适用于英文文本等问题,提出一种基于词平台汉字编码的文本信息隐藏算法,运用标志位和编码变换规则实现密文信息的嵌入,在算法的信息隐藏量和鲁棒性上有较大提高,增强密文信息的安全性。理论分析和实验结果验证了该算法具有一定实用性。更多还原

【Abstract】 Information hiding is an important way of copyright maintenance.But the existed algorithms have many problems in hiding capacity,robustness,and most of these are just suitable for English documents.Aiming at those problems,a novel information hiding algorithm is presented,which is based on Chinese characters coding method in words platform.The algorithm implements text embedding by using coding-transform rules and sign bits.The algorithm is improved greatly on information hiding capacity and robustness,and is enhanced in security of secret information.Practicability is proved by theoretical analysis and experimental results.更多还原
