Design principle DP2: Cross-validation certification

Sensor data are certified on the basis of cross-validation. Cross-validation and plausibility checks are common auditing means that reduce the risk that manipulation of the sensor or its environment goes undetected.

Source paper

This design principle is proposed by Blockchain for the IoT: Privacy-Preserving Protection of Sensor Data (Mathieu Chanson, Andreas Bogner, Dominik Bilgeri, Elgar Fleisch, Felix Wortmann, 2019).

Addresses

• Design requirement DR1: Tamper-resistant data handling

Implemented by

• Design feature DF2: Validation sensor
• Design feature DF8: Certification and verification mechanism
