Classical or traditional steganography aims at hiding a secret in cover media such as text, image, audio, video or even in network protocols. Recent research has improved this approach called distributed steganography by fragmenting the secret message and embedding each secret piece into a distinct cover media. The major interest of this approach is to make the secret message detection extremely difficult. However, these file modifications leave fingerprints which can reveal a secret channel to an attacker. Our contribution is a new steganography paradigm transparent to any attacker and resistant to the detection and the secret extraction. Two properties contribute to achieve these goals: the files do not undergo any modification while the distribution of the secret in the multi-cloud storage environment allows us to hide the existence of the covert channel between the communicating parties. Information’s are usually hidden inside the cover media. In this work, the covert media is a pointer to information. Therefore the file carries the information without being modified and the only way to access it is to have the key. Experiments show interesting comparison results with remarkable security contributions. The work can be seen as a new open direction for further research in the field.

隐藏在多云存储环境中的分布式数据

古典或传统隐写术的目的是在诸如文本,图像,音频,视频甚至网络协议等掩盖媒体中隐藏秘密。最近的研究通过分割秘密消息并将每个秘密片段嵌入到不同的封面媒体中,从而改进了这种称为分布式隐写术的方法。这种方法的主要目的是使秘密消息检测极其困难。但是,这些文件修改会留下指纹,这些指纹可以向攻击者揭示秘密通道。我们的贡献是提供了一种新的隐写术范式,它对任何攻击者都是透明的,并且能够阻止检测和秘密提取。有两个属性可帮助实现这些目标:这些文件没有经过任何修改,而在多云存储环境中机密的分发使我们可以隐藏通信方之间隐蔽通道的存在。信息通常隐藏在封面媒体内。在这项工作中,秘密媒体是信息的指针。因此,文件携带信息而无需修改,访问文件的唯一方法是拥有密钥。实验显示了有趣的比较结果,并在安全方面做出了突出贡献。这项工作可以看作是该领域进一步研究的新的开放方向。因此,文件携带信息而无需修改,访问文件的唯一方法是拥有密钥。实验显示了有趣的比较结果,并在安全方面做出了突出贡献。这项工作可以看作是该领域进一步研究的新的开放方向。因此,文件携带信息而无需修改,访问文件的唯一方法是拥有密钥。实验显示了有趣的比较结果,并在安全方面做出了突出贡献。这项工作可以看作是该领域进一步研究的新的开放方向。
