Automobile data archive system having securely authenticated instrumentation data storage

摘要

A vehicle data archive system is provided. An instrumentation interface receives at least one sensory data signal of the vehicle. A memory stores the at least one sensory data signal. A first transponder responds to a periodic provider signal of a trusted third party (TTP)/service provider for creating a corresponding shared encryption key, which is used to generate a digital signature from the stored data, the signature may be stored with the data or returned to the TTP/service provider. The signature is used to authenticate the data stored in the archive system. The encryption value used to generate the signature may be stored locally in the data archive or obtained from the TTP/service provider. The data in the data archive may also be stored without encryption. The system also allows an authorized user to delete a portion of the stored encrypted sensory data.
