现实环境中基于虚拟用户的LBS位置隐匿方法
A LBS location hiding method based on virtual users in real environment
摘要
Abstract
At present,Location-Based Service (LBS) has been widely developed and greatly facilitated people's lives.However,location exposure may reveal users' privacy,which makes the protection of location privacy increasingly important.Although current technologies can solve the privacy protection concern to a large extent,people still expect better protection of location privacy.In this regards,a privacy protection method based on real environment,named Dummy-Ex,is proposed.Through generating a series of virtual users and building realistic movements,Dummy-Ex can protect the user privacy well.Experiments show that this method can reach very good results in terms of effectiveness and safety.关键词
