System and method for safety and financial monitoring of motor vehicles
First Claim
1. A monitoring and recording system for a subject motor vehicle, comprising:
- a plurality of sensors that monitor and record vehicle parameters of a subject motor vehicle; and
wherein at least one of the plurality of sensors is a distance sensor that measures the distance to motor vehicles in front of the subject motor vehicle at any instant in time.

Abstract
The present invention is a system for monitoring and recording for later use values pertaining to the parameters of a subject motor vehicle. The monitoring and recording system includes a plurality of sensors capable of automatically measuring vehicle parameters and a system clock, both of which are in communication with a system computer. The system computer is capable of displaying and/or recording the data that is obtained (either automatically or manually) on a monitor or computer-readable medium for later use, respectively. The system can be used, for example, to monitor driving styles or to verify or detect infractions committed by the operator of the subject motor vehicle. In some embodiments, the monitoring and recording system is installed in the subject motor vehicle.

16. A method for monitoring and recording the parameters of a subject motor vehicle, comprising the steps of:
-
activating a monitoring and recording system installed in a subject motor vehicle when the subject motor vehicle is started;
capturing, digitizing and sending information measured by a plurality of sensors to a CPU of a system computer at predetermined time intervals, wherein the plurality of sensors includes at least one distance sensor that measures the distance to other motor vehicles in front of the subject motor vehicle and the system computer also includes a cryptographic co-processing unit, a non-volatile internal memory unit, and an external memory device;
storing the information obtained from the plurality of sensors for each of the time intervals in the non-volatile memory unit;
computing a hash value of the chunk of data according to one of the standard algorithms used in the art;
encrypting the hash value in the cryptographic co-processor according to a standard digital signature algorithm using a secret key stored in the non-volatile memory in order to obtain an encrypted value;
sending the encrypted value of the digital signature back to the CPU;
attaching the digital signature to the chunk of data that was hashed; and
directing the external memory device to write the data together with its digital signature onto a computer-readable medium. - View Dependent Claims (17, 18, 19)
