摘要
提出了一种基于遗传算法的机密信息还原方法。该方法首先确定嵌入扩频序列的长度;然后,采用遗传算法求得嵌入序列的最佳估计;进而,用最佳的估计序列还原出机密信息。实现机密信息的盲还原。该方法已在微机上进行模拟实验,实验结果表明,还原效果较好。
An image recovering method of confidential information based on genetic algorithm is proposed. The approach obtains the embedded sequence length firstly, and then gets the best estimated sequence by genetic algorithm, finally recovers the secret message that is hidden in the image using the best estimated sequence. Simulation results show that the presented scheme is effective and can recover the hidden information without any information from the transmitter.
