Because of the miscellaneous tricks of people¡¦s tax evasion, the government worries about this problem from time immemorial. These topics for discussion relate to both government departments and people who have to pay taxes. Present scholars add public goods in personal policy decisions to get the reasonable conclusion. It means that personal tax evasion will increase with the income tax. But in the realistic society, the circumstances are not as simple as assumption before. Comparing the governmental examine cost and the progressive income tax rate with the conclusion worked out by previous documents, and discussing that could we get more justifiable result. Furthermore, we provide a foundation for the government to set up the financial policies. This thesis indicates that both personal tax evasion and the quantity of public good will decrease when the government increases the proportion of the examine cost. It indeed reduces people¡¦s tax evasion by increasing the examine cost. However, it squeezes the quantity of public goods in the meantime. Therefore, how to get a balance on financial policies is a thoughtful issue for the government.

With the electronic commerce is going popular, many enterprise turn their business to the internet. The electronic commerce brings many problems on security and the key point is the data of the enterprise and the privacy of the customer. Firewall is not enough and the IDS is needed to provide the acceptable security. With the network monitoring and intrusion detection techniques, we can detect the attacks, alarm the administrators, and write to log files. The log files can be analyzed to provide the prevention to the same types of attacks and protect the security of the system. Recently, some attacks are proposed which can avoid the familiar IDS such as SNORT. The attack will bring a serious damage to the system. We analyze one of these attacks and try to propose a model which can detect it. We believe that the model is useful in the research of the IDS.
