Automobile data archive system having securely authenticated instrumentation data storage
First Claim
1. A vehicle data archive system, comprising:
- an sensory data interface for receiving at least one sensory data signal of the vehicle;
a data processor which associates the at least one sensory data signal with a data signature, the data signature being derived by the data processor from the sensory data using an encryption key;
a memory for storing the sensory data signal and associated data signature; and
an operator interface for selectively deleting at least a portion of the sensory data signal from the memory.

Abstract
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.

10. A vehicle data archive system, comprising:
-
an sensory data interface for receiving at least one sensory data signal of the vehicle;
a data processor which encrypts the at least one sensory data signal using an encryption key to produce an encrypted sensory data signal;
a memory for storing the encrypted sensory data signal; and
a communications module for transmitting data to and receiving data from a service provider, wherein the vehicle data archive system uses data received via the communications module to generate the encryption key. - View Dependent Claims (11, 12, 13, 14, 15, 16)
a power supply for powering the data archive when vehicle power is disrupted; and
a sound producing transducer for alerting an operator that the local power supply is in use and to assist in locating the archive.
