Abstract: 

The spread of pervasive computing through the Internet of Things (IoT) represents a challenge for privacy preservation. Privacy threats are directly related to the capacity of the IoT sensing to track individuals in almost every situation of their lives. Allied to that, data mining techniques have evolved and has been used to extract a myriad of personal information from sensor data stream. This trust model relies on the trustworthiness of the data consumer who should infer only intended information. However, this model exposes personal information to privacy adversary. In order to provide a privacy preservation for the IoT, we propose a privacy-aware virtual sensor model that enforces privacy policy in the IoT sensing. This mechanism intermediates physical sensors and data consumers. As a consequence, we are able to optimize the use of privacy preserving techniques by applying them selectively according to virtual sensor inference intentions, while preventing malicious virtual sensors to execute or get direct access to raw sensor data. In addition, we propose an ontology to classify personal information based on the Behavior Computing, facilitating privacy policy definition and information classification based on the behavioral contexts.
