【摘要】 研究了DNA序列能否成为信息隐藏的载体。通过对DNA序列进行分析证实了:由于核苷酸序列中有强的随机噪声,DNA序列可以作为信息隐藏的载体;进而通过对DNA序列特征进行分析,提出了一个嵌入对策:秘密消息嵌入非编码区的高复杂度区域有很好的安全性。该文的研究对提出以DNA序列为载体的信息隐藏算法具有重要的指导作用。更多还原

【Abstract】 Whether DNA sequences can be covers of information hiding is researched.First,the DNA sequences are analyzed and the feasibility of DNA sequences as covers of information hiding is verified because of the strong stochastic noises in the nucleotide sequences.Secondly,based on the characteristics of DNA sequences,an embedding strategy is proposed by which secret messages embedded in the high complexity regions of non_coding regions should have better security.The results are the key issues to design information hiding algorithms based on DNA sequences.更多还原
