With the expeditious expansion of the Internet of Things (IoT), an individual device’s privacy has become a huge concern for the industry, especially if medically sensitive information is being transferred. Safe and secure passage of this information to the intended destination is one of the main features of IoT. Currently, many schemes have been proposed to guarantee safe passage and secure Data Aggregation of individual device’s message(s). This work investigates present privacy concerns and data aggregation issues in IoT applications such as Wireless Body Sensor Network (WBSN) and goes through different Privacy-preserving Data Aggregation (PPDA) methods presented in Wireless Sensor Network (WSN)/IoT. Finally, this paper proposes a privacy-preserving data aggregation scheme more suitable for medically sensitive data of WBSN. The proposed scheme takes account of important differences between the WSN and WBSN, such as data redundancy and the role of individual sensors.
