With the rapid development of communication technology, mobile communication network integrates with internet constantly and forms mobile internet. The mobile communication system tend to be IP-based, mobile terminals tend to be intelligent, application of APP becomes more and more popular, intelligent applications make people's life more convenient. But, there are huge security threats hidden in current mobile communication, the security of users' privacy information in mobile communication,

This paper introduces related researches and problems of users' privacy protection in current mobile communication, and discusses to apply the idea of active defense to the security mechanism for better protection of users' privacy information. Introduction As is shown in the latest report about the development of china mobile internet, the number of cell phone netizen has been reached 500 million by the end of 2013, and continue to be the leading internet terminal. The continuous growth of cellphone netizen promotes the development of various kinds of cellphone application. Cellphone is still the major growth power of netizen in china. With the further popularization of 3G network, the commercialization of 4G networks, and the development of smart phone and wireless network, social network platform have been developing rapidly and mobile terminal applications, such as shopping online and group purchase, also have an obvious growth. Modern communication technologies change the way of traditional life, the possibility of people directly involved in the information interaction has been greatly enhanced, people's life become more convenient. But, there are lots of privacy information interacted in the process of mobile communication. Reference [1] [2] [3] [4] [5] [6] shows that it's very important to ensure its security and how to protect the security of users' privacy information has attracted widespread attention. Virus in cellphone has been emerging endlessly, since the world's first cellphone virus appeared in 2004. Its hazards involved malicious deduction, stealing privacy, and mad message. The undercover software appeared in 2010 can send communication record and confidential information that stored of cellphone users to specified monitoring site. These malicious events threatened the communication security of users' privacy. Meanwhile, it not only destroyed the social harmony and stability, but also posed a threat to national security. Reference [7] the popularity of intelligent terminals and the maturity of mobile application environment bring a bright prospect for mobile P2P networks. In recent years, the security of cellphone users' privacy tend to be more severe with the widely use of mobile applications, and we are facing with the risk of privacy disclosure whenever and wherever you are. For example, the navigation software need to share our location information in real-time when we use it, which reflect the users' behavior path. If the software are attacked, the user will 318 Copyright ⓒ 2015 SERSC be followed, which cause the leak of users' location privacy. Currently, the mobile internet environment has been deteriorating, the upstream links, such as cellphone shops, BBS and download site have been polluted, which speed the infection of downstream users. There are more than 703 thousands new mobile internet malicious programs in 2013, increased 3.3% compared to 2012. In addition, new technologies and internet business, such as cloud computing, mobile internet and social network, change the way of collecting and using personal information, which makes the security of personal information less controllable and the potential threat of personal privacy information leak intensified. For example, the use of cellphone number as the unique identifier account in applications becomes more and more common. Reference [8] shows that researches carried out by Schrittwieser showed that it will bring a lot of security problems. The security mechanism of mobile communication has been improved after several generations development, and to some extent, it can protect users privacy. But, it still is a passive defense mechanism, and reference [9] shows that there are a lot of security vulnerabilities which can't ensure absolute safety of users' privacy information. Therefore, a new security mechanism is needed to adapt to the rapid development of mobile communication technology, the defender need to game with the attacker actively so that users' privacy information can have a better protection. This paper makes an overview of the existing security mechanism of privacy protection, and introduces the active protection technology, and discusses the application of dynamic defense mechanism to privacy protection in the mobile communication. Privacy Data in Mobile Communication Privacy data is very important information related to users' identity, including mobile station integrated services digital network number(MSISDN), international mobile subscriber identification number(IMSI), user's location, and so on, which is transparent associated storage and use in multiple equipment in mobile communication network. Nowadays, with the development of communication technology, mobile communication can provide value-added personalized service basing on user's privacy information,such as identity information, location information, and so on. As the credentials for users to access and use network resource, the privacy information must be well protected by the system. However, the current reality is not optimistic. The communication systems are facing many conflicts and contradictions, such as content supervision and content diversity, user's convenience and privacy data security. If lacking of effective supervision, greater security threat will be brought to user. Therefore, the security of user's privacy data existing in mobile communication network arouses more and more widely attention, it is necessary to take measures to protect the security of privacy information better. Hidden Danger of Privacy Data Security in Mobile Communication Great changes have taken place in the way of our life, with the rapid development of mobile communication technology, the mobile terminal become intelligent, the mobile application platforms become diversity. Nowadays, people almost can't live without cellphone in daily life. Cellphone has taken up much of people's time and energy. More importantly, there is a huge hidden risk of privacy information security, while user enjoying the convenience of intelligent terminal. Security events disrupt the security environment of global information, and network space, as the fifth dimension of the world today, its security is the greatest security issue human facing today. Therefore, it's imminent to solve the security problem of users' personal privacy information in mobile communication. There are many reasons that caused the leak of users' privacy information in mobile communication, which can be basically divided into two categories. 322 Copyright ⓒ 2015 SERSC security, network security, user security, application security and visibility and configuration of security, to guarantee the security of user's privacy information from every aspect.
