摘要： 针对动态Web页面资源中的实施细粒度和透明访问控制问题，定义片断的概念，提出基于数据流分析的“片断”级Web页面资源的访问控制方法，分析数据流中的请求信息与响应片断的关系，设计并实现了2种数据流片断识别算法。模拟系统的实验结果证明，该方法能有效识别动态Web页面资源的片断，满足细粒度访问控制的需求。

Abstract: In order to take fine-grained and transparent access control for dynamic Web pages resource, this paper defines “fragment”, presents an approach of fragment-level access control for Web pages resources based on data stream analysis, which analyses the relation between request and response fragments, and designs and realizes two kinds of arithmetic for fragment identify. Experimental results demonstrate the approach can identify dynamic Web pages resource and take fine-grained access control.

Key words: Web pages resource, fragment, fine-grained access control, data stream
