摘要：The sign-in service of Mobile Social Networking Services (MSNS) has a serious issue of privacy disclosure. As to solving this issue, there is a method proposed to protect privacy. This method is to conduct binary coding for sign-in sequence and then construct ant path diagram. The random search, the positive and negative feedback principle of ant path graph are applied to mine frequent item sets. The longest common subsequence is achieved from sign-in sequence and corresponding frequent item sets. Finally, k- anonymous sign-in sequence will be obtained. Based on real data, this method is compared with anonymity - ) , ( . k which proves the accuracy and efficiency of this method through various aspects.
