Security, Privacy, and Transparency Improvements of CoMaDa

State: Assigned to Michael Balmer

Due to the growth of the Internet and the device diversity together with their communication capability the Internet of Things (IoT) is a hot topic. The Internet of Things is not limited to Peer-to-Peer (P2P) networks and devices like server, computers, and routers any more. It also includes wireless sensor devices connected in a Wireless Sensor Network (WSN).

The application range goes from intelligent homes, logistic, health care to environmental monitoring. All applications have in common a huge amount of collected sensor data (e.g., temperature, brightness, humidity) under different operating systems. The collected data also includes sensitive data and might be access by authorized persons. Data owners have concerns on security and privacy, especially who accessed which data and when. In order to address this transparency concern a solution must be developed giving the data owners the opportunity to follow this data access and can only access this filtering information if they are authorized.
SecureWSN is the existing framework this Bachelor thesis will build on. It allows data collection and visualization of data for constraint devices. In the background a database is running logging collected data and supporting the access management. In the Front-end data owners have the opportunity to grant access rights and see collected data. The already established solution has the drawback that collected data is stored in a database in the back-end that can only accessed by the database administrator, who is a different person compared to the data owner. Further, the data owner is only able to see his collected data and granted rights to authorized users, but not when and which data was access. Currently to graphical user-inter- faces are in place where the data owner can see his data. Those are CoMaDa and WebMaDa that will undergo an extension to address the aforementioned security and privacy concerns of data owners.
