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。
