| 摘 要： | 提出一种基于七巧板游戏的数字图像信息伪装方法，将机密数字图像和载体图像都分成适当的小块，按一定的条件寻找最佳匹配关系，然后将描述匹配关系的参数经编码后隐藏在载体图像中，到接收方提取参数，利用匹配关系恢复出机密图像。

| Abstract: | This paper proposes a digital image steganography method based on Tangram. It divides both secret image and carrier image into appropriate small blocks in the same way,for each block of the secret image,to find the best match block from the carrier image blocks according to the setting condition, then to hide the encoding of the parameters which depict the match relationship into carrier image. For the receiver, it picks up the parameters from the carrier image and restores the secret image by the match relationship. |
