Therein, by adopting the ISCSI protocol, the local data storage sub-system constructs the circuital access pattern of the taxation data. The system eliminates the unbalance phenomena between the capability and the demand of the data storage under the traditional bus storage pattern. Under the centralized control pattern, it provides the information access and shares service with the great data volume, the high speed of data transportation and the high availability for the taxation system. By remotely building a backup data center that is totally consistent with the local data center on the IT foundational fabric, the remote data backup sub-system uses the geographical dispersibility of the remote data center and adopts the LVR software replication technology. It implements the synchronous data replication between the local and remote data center, changes the zero standing capability on the great disaster event under the single data center pattern and raises the standing capability on the disaster events for the application and data in the taxation system. By adopting the dynamic replication technology between the heterogeneous data source, the heterogeneous data conformity sub-system successfully shields the various heterogeneous ingredients of the present system.

其中，本地数据存储子系统采用ISCSI协议构建了税务数据网络存储模式，消除了传统总线型存储模式下数据存储性能和存储需求之间的失衡现象，在集控管理模式下为税务系统提供了超大数据容量、高数据传输率和高可用性的信息存取和共享服务；远程数据备份子系统通过在异地构建一个和本地数据中心IT基础架构完全一致的备份数据中心，利用远程数据中心在地理上的分散性，基于LVR软件复制技术实现了本地和远程数据中心之间信息的实时同步，改变了过去单一数据中心模式下对大型灾难事件的零抗灾能力，提高了税务系统内应用和数据对灾难性事件的抵御能力；异构数据整合子系统采用异类数据源动态复制技术，成功屏蔽了目前系统内存在的各项异构成分。

This paper analyzed data from multiple sources and different structures, concluded three types of info: Login info, Event info, and Packet data info, then created the formation for every type of data; In order to combine future possible new data, IDS using profile and formation string together, create and practice data formation standard algorithm; Because in the collected data, there is info that is redundant or has minor effect on the IDS, this paper discussed the rules of redundant data differentiating and safe data differentiating, Then create data filter rule base; Data collecting system uses distributivity design, collecting module like a black box. we can get data which was filterd and had standard formation, if we created a new model string for new data source. Module work individually; filter data right away at the collecting node.

本文分析了多种来源的、不同结构的数据，将其总结成登录信息、事件信息和网络数据包信息三种类型，并为每种类型的数据设计了固定的格式；为了与将来可能出现的新型数据兼容，采用了配置文件与模式字符串相结合的方法，设计并实现了数据格式标准化算法；由于收集到的数据中存在冗余的信息和对入侵检测影响不大的信息，本文分别讨论了冗余数据辨别规则和安全数据辨别规则，并建立起数据过滤规则库；数据收集系统采用分布式设计，收集器以黑盒形式提供，对新的数据源只需设计一个新的模式字符串，即可得到过滤后的、具有标准格式的数据，各收集器间独立工作；在收集点即对数据进行过滤，只向分析中心报告可疑数据，以减少传输和存储的数据量，降低对网络性能的影响。

The block-based fractal image compression method has a low compression ratio, so simple region-based fractal image compression is introduced, then the competitive region-based fractal image compression method is presented. The experimental results show that the compression ratio is effectively improved at a similar PSNR value.

由于基于块的分形图像压缩方法的压缩比不高，对此进行改进，先介绍简单的基于区域的分形图像压缩，然后提出基于区域的竞争分形图像压缩算法，并进行实验，实验结果表明，该方法在保持一定的信噪比的情况下，有效的提高了压缩比。
