With the development of the Internet , covering the range of services provided by the Internet is more extensive and diverse , to further strengthen the information society dependent on the Internet , while the emergence of new applications and the introduction of new technologies to the Internet has brought a more serious security problem . Continues to be the mainstream Web - based attacks , browser security issues have become increasingly prominent ; attention of privacy information leakage problems in the process of the browser Internet users in the use to improve . In this paper some of the key technical issues of Internet security threats , Safe Browsing the structure model and the browser fingerprint recognition model . In this paper, gives its browser security label of the properties of the multi-level algorithm , new design methods and next-generation mainstream browser ( Chrome) is similar to the modular design . Lack of strategy for SOP (Same Origin Policy) , the design of new criteria for the classification of the object granularity , set up multiple security attributes in each object attribute group tags, security attributes to consider its weight and calculate the trust value , access control can be based on the trust value of each object , this design solved the problems of the SOP the granularity is divided dilemma , can better meet the Mashup technology can prevent malicious link request similar to XSS attacks like initiated from within . The browser fingerprint technology matures privacy policies and technical design can not be ignored . In this paper, a fingerprint recognition algorithm based on the the browser characteristics of information entropy browser , first discussed the browser features information generated by combining fingerprint must consider two issues : diversity and stability , and the browser fingerprint information entropy representation , design upgrade fingerprint recognition algorithm of the the browser fingerprint recognition algorithm based on a small amount of configuration information changes . Finally from fingerprint Privacy Enhanced protection technology of the two sides , the enumeration function provides version information of the level of detail and the order of the font information contains information and several additional discussions .
