Protection of privacy in pervasive computing environments
Huan Cheng, Dali Zhang, Jiaqi Tan · 2005
In this paper, we present two techniques. The first technique called privacy sensitive information diluting mechanism (PSIUM) is able to prevent the misuse of data by a service provider by using a mixture of true and false sensor data. The second technique protects privacy sensitive information from being revealed to an attacker through traffic analysis by using a combination of frequently changing pseudonyms and dummy traffic.
