And use center of data of financial class safety, the communication mechanism of system of ATM of similar silver couplet will ensure the safety of data, anybody cannot revise among them information and data, put an end to any trying that pass to distort thoroughly thereby, be modelled on false information undertakes jobbery, escape paying behavior!

且采用金融级安全数据中心，类似银联ATM系统的通讯机制来保障数据的安全，任何人都无法修改其中的信息和数据，从而彻底杜绝了任何试图通过篡改、仿制虚假信息进行营私舞弊、逃避支付的行为！

"Center " namely " management center of Internet bar of toot toot ox ", it is important to be used at memory, test and verify and administrative user important information and Internet bar manage information, account of data " center type operation to run a system ", this system uses financial class to install complete data center, the communication mechanism of system of ATM of similar silver couplet will ensure the safety of data, anybody cannot revise among them information and data, put an end to any trying that pass to distort so, be modelled on false information undertakes jobbery, escape paying phenomenon.

"中心"即"嘟嘟牛网吧治理中心"，用于存储、验证以及治理用户重要信息、帐户重要信息和网吧经营数据的"集中式运营治理系统"，该系统采用金融级安全数据中心，类似银联ATM系统的通讯机制来保障数据的安全，任何人无法修改其中的信息和数据，这样杜绝了任何试图通过篡改、仿制虚假信息进行营私舞弊、逃避支付的现象。

Center toot namely management center of toot ox Internet bar, it is important to be used at memory, test and verify and administrative user important information and Internet bar manage information, account the concentration of data type operation runs a system, this system uses financial class to install complete data center, the communication mechanism of system of ATM of similar silver couplet will ensure the safety of data, anybody cannot revise among them information and data, put an end to any trying that pass to distort so, be modelled on false information undertakes jobbery, escape paying phenomenon.

He brilliantly parodied Mies van der Rohe's dictum that "less is more" in his motto "too much is never enough", and his buildings revel in the amoeboid plans, Swiss cheese-holes, stick columns and kidney-shaped swimming pools so characteristic of the age.

The image is first reduced in dimension by Gaussian pyramid, and the Hu moment is applied to the fixed sized overlapping blocks of low-frequency image. The eigenvectors are lexicographically sorted. Then, similar eigenvectors are matched by a certain threshold value. Finally, the area threshold value is proposed to remove the wrong similar blocks. The mathematical morphology operations are performed to locate the tampered part.

该算法首先将图像进行高斯金字塔分解，将低频图像进行块分解，提取每块的Hu矩不变特征，并将特征向量排序，然后为每个特征向量搜索符合阈值的相似特征向量；最后利用区域面积阈值去除错误的相似块，并结合数学形态学定位篡改区域。

And the algorithm is of high sensibility to malicious modified data, of robustness to some noise disturbance, lossy compression and so on.
