| 中文摘要:传统的隐写方法是将秘密信息嵌入到载体中，而利用生成式对抗网络(GAN)的无载体信息隐藏技术逐渐成为目前最有潜力的研究方向。本文在一种基于GAN的无嵌入信息隐藏方法的基础上，进行了研究与改进。信息发送方首先利用噪声驱动生成器直接生成含密图像，信息接收方通过秘密信息提取器提取出有效的秘密消息，改进提取器的训练任务，并引用冗余纠错编码技术以提高信息提取的准确率。实验结果表明，相比同类方法，本文方法在保持高隐写容量的情况下，具有更高的信息提取准确率，同时收敛速度大大提高。引入纠错码技术大幅提高了秘密信息提取的准确率，具有一定的实用性。 |

| Abstract:Traditional image steganography algorithms embed a secret message into a cover image. However, steganography without em-bedding, which uses Generative Adversarial Networks (GANs), has become the most potential direction in information hiding at present. We studied and improved a steganography method without embedding based on GAN. First, the sender uses a generator as the noise driver to generate the cover image. Next, the receiver extracts the secret information using the extractor, and then com-pletes secret communication. In the process of extracting information, improvement of the extractor training task and redundant correcting code technique is utilized to improve information extraction accuracy. Experimental results show that, compared with similar algorithms, the proposed method ensures higher information extraction accuracy while maintaining high steganography capacity. Meanwhile, the convergence speed of training is also greatly improved. The introduction of error-correcting code technology greatly improves the accuracy of secret information extraction and has certain practicability. |
