Based on the coupled discrete tent spatiotemporal chaotic maps, a cryptographic Hashing function is constructed to generate 128-bit Hash value from a message with arbitrary length.

与帐篷映射相比，该方案所采用的离散耦合帐篷时空混沌模型避免了有限精度实现产生的短周期行为，产生的时间序列近似服从均匀分布，具有更为理想的扩散与混乱特性。

The idea of digital ideograph of an abstract of the image related to sub-block was made with the function of Hash, and a digital watermarking encrypted, which can show whether the sub-block changes or not.

该水印是根据图像子块内容自适应生成的，图像子块内容如果有了显著变化，就会在水印中表现出来。

You have to hash something out in a hury.

你们需要在短时间内解决这个疑难问题。

Since image ID and block index serve as parts of input to hash function,the algorithm also can efficiently resist to collage attack.

由于图像的标识和区域块的索引当作哈希函数输入的一部分，因此本文的方法可以有效抵抗拼贴攻击。

This is because the SHA1 is designed so that it is infeasible to find different contents that produce the same hash.

这是因为 SHA1 算法就设计成对于不同的内容不可能产生相同的哈希特征值。

At the end of this paper, we investigate the invertible problem with the watermarking algorithms, and analyze the situation of image ownership dispute caused by the possible counterfeit attack for the reason of invertibility. Then we discuss one method based on one-way hash function to make the watermarking algorithms non-invertible, and another one using the time stamping protocol, to prevent the counterfeit attacks.

本文随后研究了水印算法的可逆性问题，对于由此可能发生的伪造攻击致使对图象所有权产生争议的情况作了分析，并且讨论了基于单向Hash函数的使水印算法不可逆的方法，以及采用时间戳协议以阻止伪造攻击的方法。

"If there's a real hash, the client can get infections," says Kingsley.

如果处理失当，客户可能会感染，"金斯利说。"
