摘要:

针对生成式隐写存在的生成图像与真实图像相差较大、图像翻译隐写需要训练大量模型等问题,文章提出了基于StarGAN的生成式图像隐写方案。该方案仅需一个模型即可完成多风格图像翻译任务。发送方将秘密信息进行编码,映射为图像的风格标签,然后生成相应风格的图像,发送给接收方;接收方使用秘密信道传递的提取模型,对图像进行风格标签的提取,并对照编码方式解码出秘密消息。实验结果表明,该方案在减少训练模型数量的同时,图像质量、消息提取准确性等方面均有明显提升。

Abstract:

Aiming at the problems that the generated image and the real image are different in the generative steganography, and the image translation steganography needs to train a large number of models, a generative image steganography scheme based on StarGAN is proposed. Only one model can complete multi-style image translation task. The sender encodes the secret information, maps it to the style tag of the image, generates an image of the corresponding style, and sends it to the receiver. The receiver uses the extraction model which passed by the secret channel to extract the style tag of the image, and compares the encoding method to decode the secret informatione. The experimental results show that while reducing the number of training models, the scheme has significantly improved image quality and information extraction accuracy.

Key words: information hiding, deep learning, generative steganography, image translation
