In this paper, we put forward both the set of method and the series of process for extracting parallel sentence pair from nonspecific web date source. considering 1.1 billion page as the web data input, with a sequence of steps we get several sentences pair which has 81% recall and 85% precision, on this basis we bring up a parameter for measure quality of sentence pair. After filter sentence pair by this parameter, we get 850 thousand unique sentence pairs. On filtering by this parameter, the precision increase to 95%, meanwhile the recall only decrease by 1%.","PeriodicalId":216097,"journal":{"name":"Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114347050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The typical and primary two kinds of bypass vulnerabilities are authentication and access control vulnerabilities. Authentication attacks occur when a web application authenticates users incorrectly and grants access for users without appropriate credentials. Access control attacks happen when access control check is incorrect or missing, allowing unauthorized access to privileged resources. Such attacks are getting increasingly common and have occurred in many famous web applications such as IIS and WordPress, and 14% of surveyed web sites [5]. However, currently no available tools or methods can prevent these attacks efficiently. By using Dynamic Information Flow Tracking (DIFT) techniques to track the flow of user credentials through the application's language runtime, the model presented in this paper can automatically detect when an application safely and correctly authenticates users. Then the model combines authentication information with programmer-supplied access control rules to automatically ensure that only properly authenticated users are granted access to privileged resources or data.","PeriodicalId":216097,"journal":{"name":"Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114968479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
