Description
- The present invention regards an electronic and processing device, and a related inner computing process able to achieve the certain acquisition and secure storage of real dynamic data and location data related to the motion of a road vehicle, or motion of an aerial or sea vehicle, on which the same device is steadily jointed.
- The certain acquisition and secure storage of data related to the motion of a vehicle permits to achieve, by the inner data processing, the evaluation of the style of use of the vehicle and the detection of unusual dynamic situations that can be related to possible accidents, in reference of which the device records the sequence in time of the dynamic forces detected on the vehicle and generates respective automatic alarm messages that are transmitted to a remote server.
- As known, in the automotive industry the use of the so called "black boxes" on board of vehicles is proposed as an opportunity of gaining discounts on the insurance costs, giving in change a better control by insurance companies on the "driving behavior" of drivers, and on the dynamics of car accidents involving vehicles covered by insurance contracts. Considering the existing devices on the market, there has been a poor attention to aspects connected to "data security" with reference to confidentiality, integrity and genuinity of data, because most part of devices manages the location data "in clear", that means that anybody having access to them can read them, and further there is no process that guarantees the "integrity" of data (that is that no information has been hidden or deleted), that guarantees the "certain source" (that is that no information can be generated outside the device that is installed on board of the vehicle covered by insurance).
- Furthermore, the different standards in the different products do not permit to compare data coming from a specific device in respect to data coming from another device and, consequently, the interpretation of data recorded during an accident cannot be univocal.
- Therefore, as a consequence, data coming from "black boxes" are hard to be used as evidence to be produced in front of a court because they depend on interpretation that is "subjective" and not "objective".
- Another matter, usually neglected, is that of "survival" of devices in respect to damage due to serious accidents: large part of devices available on the market are capable to provide data only in case they are kept undamaged, and in case that data have not been transfered to a remote control center before an accident, data are definitely lost because of broken device due to the accident.
- Furthermore, up to date the environmental compatibility of devices has not been considered a critical matter, even considering that many devices cannot work properly in very hard situations or under the water, and they are not designed to operate in fire risk environments (according to ATEX rules).
- The approach followed to design the device of the present invention, called STM Box, is focused instead to important matters as security, reliability, environmental compatibility and possibility to data comparison of different devices, achieving an instrument that can provide the best data protection in any operative and environmental situation.
- In particular, the STM Box is able to enable the following functions:
- detection of data concerning positioning and dynamic forces (accelerations and rotations) to which the vehicle has been submitted;
- recording of data concerning a geographic path followed;
- processing of dynamic data and recognition of conditions that are typically associated to an accident;
- decoding of data received from the remote server and verifying of their genuinity comparing their digital signature;
- providing digital signature to data to be transmitted to the remote server and encoding of the same data in order to protect them from a non authorized access;
- autonomous processing of data that characterize the "driving behavior" of the driver and real time processing of a "synoptic dashboard" of the risk indexes.
- Even in case of malfunctioning, or manipulation or damage of the device on board, the STM Box would save its integrity and it would not be possible to change the processing or modifying the data stored inside.
- The data stored inside permit to reconstruct, with good approximation, the trajectory followed by the vehicle at the time immediately before and after the instant of an impact, giving the acceleration data, the angular velocity data, and the GPS data with the best possible accuracy, further providing the elements that permit to estimate the position and seriousness of damage in different parts of the vehicle, and permit to estimate the entity of the possible damage to persons transported within the vehicle.
- The original aspects of the STM Box can be enlisted in the following:
- Personal Data Protection:
- transmission to the remote server of the data only related to the accidents;
- data of travelling path and events (accidents) within the STM Box (not accessible);
- data transmitted in encryption mode (guaranteed to be protected);
- data with digital signature (guaranteed the integrity and genuinity);
- data physically protected in front of possible malfunction by damage (IP.68 protection);
- data can be read even in case of damage of the device.
- Use of Recorded Data:
- 30 seconds of dynamic recording in case of "relevant events" (real or possible accidents);
- sending of an "alert" message in case of recorded events recognized as accidents;
- possible enquiry later "ex post" in case of recorded events not recognized as accidents;
- processing of synthetic indexes revealing the level of risk in driving behavior (processing within the STM Box).
-
- sending of alert messages to the remote server in case of accident;
- sending of alert messages in case of "custom" events chosen by client (going beyond a level of velocity, or level of time, going outside a geographical area, etc.);
- check and control of the use of the vehicle during interruption of the insurance contract;
- automatic call to the service headquarter (in case of accident);
-
- protocols, algorithms, file formats and message formats are open and public;
- it is possible to integrate STM Box in networks of third parties;
- it is possible to integrate STM Box within new vehicles at the factory;
- encryption and digital signature methods based on public algorithms (RSA, AES);
- data property;
- device movable from a vehicle to another in case of change of vehicle;
- device movable from a company to another in case of change of insurance company;
- possibility of insurance surrender of the device on board by the client.
- Therefore, the present invention concerns an electronic and processing device, called "STM Box", and a related inner computing process, able to achieve the certain acquisition and secure recording of dynamic data and location data related to the motion of a road vehicle, or motion of an aerial or sea vehicle, on which the same device is steadily jointed, and able to transmit the same data to a remote site, or to a remote server, by using a radio communication network, that is further connected to a service headquarter, characterized in that:

- The certainty of the acquisition of dynamic data is assured by the fact that the device contains inside, in a physically inaccessible manner: a satellite receiver that is able to detect the current geographical coordinates in real time, sensors of direction, rotation and acceleration along the three mechanical axis if the same device, and a storage memory in order to save the data.
