中文摘要:
提出了一种新型的基于载体选择的无载体隐写方案.发送端以迭代量化哈希为基础建立秘密信息与载体图像的联系,并根据此联系从图像库中选择合适的载体进行秘密信息传输,接收端根据事先约定好的规则,使用图像哈希技术从图像中提取出秘密信息.实验证明此方案在安全性方面优于传统的基于信息嵌入的隐写方案,且在鲁棒性与隐写容量方面略优于其他的无载体隐写方案.
English Summary:
A novel coverless steganography method based on cover selection was proposed. The sender was arranged firstly to establish a connection between the secret information and the cover image based on the iterative quantization hashing, and then to select the appropriate cover from the image set to transmit the secret information according to the connection. According to the pre-agreed rules, the receiver was arranged to extract the secret information from the image based on the image hashing technique. Experiments show that this method is superior to the traditional information-embedded steganography method in terms of security, and is slightly better than other coverless steganography methods in terms of robustness and steganographic capacity.
