文摘An adaptive algorithm for removing false ridges, bridges and filling gaps in binary fingerprint images based on morphological operations is presented. A novel procedure for structuring elements design based on the specific fingerprint characteristic is described. Using the images from FVC2000 database, we have compared our method proposed here with the approach proposed by other ones. The Experimental results have demonstrated the efficiency of our method.
文摘什么是OS fingerPinting？我们知道，基于TCP／IP体系的网络操作系统平台的产品非常多，尽管这些操作系统都实施TCP／IP网络架构，但是每一种操作系统在具体实现TCP／IP协议栈时，使用的思想方法又不一样，因此，就形成了操作系统互操作性上的异质性，这种异质性我们可以称作操作系统的指纹。如同人类指纹一样．每个操作系统的指纹(O S fingerprinting)也是惟一的。通过取得操作系统的指纹信息，我们可以确定网络平台所使用的操作系统的类型。获取的方法一般有两种，一种是向目标主机发一个特定的数据请求包，依据目标主机的响应的答复包里的信息，判断目标主机的操作系统类型；另一种方法是用网络监视设备，截获来自目标系统的数据包，取出OS fingerprinting，判断目标系统的操作系统类型。
