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.
