SYSTEMS AND METHODS FOR TRACKING HISTORIC DRIVER DATA ON THE EDGE
Driver insurance and risk management scores are calculated per driver based on vehicle and driver behavior data collected during driving sessions. Often one vehicle is shared by multiple drivers and one driver can drive multiple vehicles. The present disclosure securely tracks the individual drivers, stores, and retrieves associated driver data for analysis on the edge (vehicle) in near real time. Data collected is analyzed at various time intervals (each trip, daily, monthly) to produce the scores. The goal of the proposed solution minimizes cost associated with data transmission and cloud storage, tracks long term driver driving history on the edge for near real time analysis of driver behavior, minimizes driver distraction due to user device while driving, securely stores and retrieves driver driving data on the edge device associated with the driver, restricts access to the driver driving data, and restricts user device access to servers and telematic units.
1 . One or more non-transitory computer readable media storing computer-executable instructions that upon execution cause one or more processors on a server to perform acts comprising:
receiving a communication from a telematic unit, the communication includes a first request for a first symmetrical key,
receiving a first encrypted historic data, and a user device identification corresponding to a user device;
retrieving a second encrypted historic data and the first symmetrical key corresponding to the user device identification from a database;
hashing the first encrypted historic data generating a first hashed encrypted data
hashing the second encrypted historic data generating a second hashed encrypted data;
comparing the first hashed encrypted historic data to the second hashed encrypted historic data;
generating a second symmetrical key; and
storing the second symmetrical key in the database.
2 . The one or more non-transitory computer-readable media of claim 1 , wherein the telematic unit hashed the first encrypted historic data from the user device prior to transmission to the server.
3 . The one or more non-transitory computer-readable media of claim 1 , further comprising transmitting the first and second symmetrical keys to the telematic unit when the first hashed encrypted historic data matches the second hashed encrypted historic data.
4 . The one or more non-transitory computer-readable media of claim 1 , further comprising transmitting the first and second symmetrical keys, and the second encrypted historic data to the telematic unit when the first hashed encrypted historic data and the second hashed encrypted historic data do not match.
5 . The one or more non-transitory computer-readable media of claim 1 , further comprising:
receiving a second request from the telematic unit for the first and second symmetrical keys and historic data when the user device does not contain user device historic data;
transmitting the historic data and the first and second symmetrical keys to the telematic unit when the server contains the historic data; and
transmitting a no historic data message to the telematic unit when the server does not contain the historic data.
6 . The one or more non-transitory computer-readable media of claim 1 , further comprising:
receiving, from the telematic unit, encrypted trip data for a new user device, a new user identification, a new user device identification, a telematic unit identification, and a timestamp.
7 . One or more non-transitory computer readable media storing computer-executable instructions that upon execution cause one or more processors on a telematic unit to perform acts comprising:
transmitting a first request to a user device, the first request for a first encrypted historic data and a user device identification;
receiving the first encrypted historic data from the user device;
hashing the first encrypted historic data and generating a first hashed encrypted historic data;
transmitting a second request to the server, the second request for a second symmetric key;
transmitting the hash and user identification to the server; and
receiving the first symmetrical key and the second symmetrical key from the server when the first hashed encrypted data matches a second hashed encrypted historic data stored on the server.
8 . The one or more non-transitory computer-readable media of claim 7 , further comprising:
receiving a second encrypted historic data from the server when the first hashed encrypted data does not match the second hashed encrypted historic data;
decrypting the second encrypted historic data using the second symmetrical key; and
storing the second encrypted historic data in a memory device on the telematic unit.
9 . The one or more non-transitory computer-readable media of claim 7 , further comprising transmitting a third request to the server, the third request for a third encrypted historic data and the first and second symmetrical keys when the user device does not contain any encrypted historic data.
10 . The one or more non-transitory computer-readable media of claim 9 , further comprising:
receiving a second encrypted historic data from the server when the first hashed encrypted data does not match the second hashed encrypted historic data;
decrypting the second encrypted historic data using the second symmetrical key; and
storing the second encrypted historic data in a memory device on the telematic unit.
11 . The one or more non-transitory computer-readable media of claim 7 , further comprising:
receiving a no historic data message from the server upon a determination that the server does not contain the first encrypted historic data; and
creating a record on the telematic unit for the user device.
12 . The one or more non-transitory computer-readable media of claim 7 , further comprising:
determining an end to a trip in a vehicle, the trip generating a trip historic data;
updating the first encrypted historic data from the user device with the trip historic data;
encrypting the first updated encrypted historic data; and
transmitting the first updated encrypted updated historic data to the user device.
13 . The one or more non-transitory computer-readable media of claim 12 , further comprising:
sending the first updated encrypted historic data to the server along with the user identification, a user device identification, a telematic unit identifier, and a timestamp.
