发明名称 Protection of sensor data
摘要 The sensor module has a sensor for detecting consumption data or biometric characteristics and an integrated data protection device for preventing unauthorised data read-out or data manipulation. The sensor module data may be protected by a tamper-proof module, e.g. with a cryptographic function, with read-out of the data only after access authorisation via a question and answer protocol.
