Abstract
Abstract A device (100) and method (200, 300) authenticate and secure control event data for a vehicle, wherein the device includes: A) a microcontroller (104), coupled to receive control event information, for attaching a first time stamp and vehicle identification number VIN to the control event information to provide first information and sending the first information to memory (106) in time overlap fashion; B) the memory (106), coupled to the microcontroller (104) and a microprocessor (108), for storing first information and second information in time overlap fashion; and C) the microprocessor (108), coupled to the memory (106) and a plurality of transducers (110), for determining whether received impact data varies from previous impact data, and where received impact data varies, adding a second time stamp and VIN to the received impact data to form second information.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
A device for authenticating and securing control event data for a vehicle, comprising: A) a microcontroller, coupled to receive control event information, for attaching a first time stamp and vehicle identification number VIN to the control event information to provide first information and sending the first information to memory in time overlap fashion; B) the memory, coupled to the microcontroller and a microprocessor, for storing first information and second information in time overlap fashion; and C) the microprocessor, coupled to the memory and a plurality of transducers, for determining whether received impact data varies from previous impact data, and where received impact data varies, adding a second time stamp and VIN to the received impact data to form second information.
Claim 2
Independent Claim
120 words
A device for authenticating and securing control event data for a vehicle, comprising: A) a microcontroller, coupled to receive control event information, for attaching a first time stamp and vehicle identification number VIN to the control event information to provide first information and sending the first information to memory in time overlap fashion; B) the memory, coupled to the microcontroller and a microprocessor, for storing first information and second information in time overlap fashion; and C) the microprocessor, coupled to the memory and a plurality of transducers, for determining whether received impact data varies from previous impact data, and where received impact data varies, adding a second time stamp and VIN to the received impact data to form second information.
Claim 3
Dependent Claim
36 words
The device of claim 1 wherein the device further includes an auto-lock unit coupled to the microprocessor for sending a signal to the memory to lock the first information and the second information in unchangeable form.
Claim 4
Dependent Claim
32 words
The device of claim 1 wherein the device further includes a manual lock for sending a signal to the memory to lock the first information and the second information in unchangeable form.
Claim 5
Independent Claim
196 words
A method for authenticating and securing control event data for a vehicle, comprising the steps of: A) sending control event information and data to a microcontroller; B) attaching, by the microcontroller, a first time stamp and vehicle identification number to the control event information and data to provide first information and sending the first information to a memory; C) storing the first information in a list in the memory in time overlap fashion; D) determining whether one of: an ignition of a vehicle is in off position and a predetermined time has elapsed, and where one of: the ignition is on and the predetermined time is unelapsed, determining whether any other control event has occurred; E) where another control event has occurred, returning to step A; F) where another control event has failed to occur, ending; G) where one of: the ignition is in an off position and the predetermined time has elapsed, sending instructions to the memory to start a new list in overlap fashion; H) determining whether another control event has occurred; I) where another control event has occurred, returning to step A; and J) where another control event has failed to occur, ending.
Claim 6
Independent Claim
196 words
A method for authenticating and securing control event data for a vehicle, comprising the steps of: A) sending control event information and data to a microcontroller; B) attaching, by the microcontroller, a first time stamp and vehicle identification number to the control event information and data to provide first information and sending the first information to a memory; C) storing the first information in a list in the memory in time overlap fashion; D) determining whether one of: an ignition of a vehicle is in off position and a predetermined time has elapsed, and where one of: the ignition is on and the predetermined time is unelapsed, determining whether any other control event has occurred; E) where another control event has occurred, returning to step A; F) where another control event has failed to occur, ending; G) where one of: the ignition is in an off position and the predetermined time has elapsed, sending instructions to the memory to start a new list in overlap fashion; H) determining whether another control event has occurred; I) where another control event has occurred, returning to step A; and J) where another control event has failed to occur, ending.
Claim 7
Independent Claim
186 words
A method for authenticating impact data and control event information in a vehicle, comprising the steps of: upon transducers being impacted, A) sending impact data to a microprocessor; B) determining whether impact data varies and where impact data fails to vary, ending, and where impact data varies, adding a time stamp two and a vehicle identification number to the impact data to form second information and storing the second information in memory; C) determining whether a manual lock is in use and: where the manual lock is in use, using the manual lock to retain the second information unchanged in memory; and where a manual lock fails to be in use, using an auto lock to retain the second information unchanged in memory; D) obtaining first information on control events and data and comparing with second information; E) determining whether the first information and the second information is synchronized; F) where the first information and the second information fails to be synchronized, reporting unauthenticated data/tampering; and G) where the first information and second information is synchronized, storing the first information and the second information in memory.
Claim 8
Independent Claim
186 words
A method for authenticating impact data and control event information in a vehicle, comprising the steps of: upon transducers being impacted, A) sending impact data to a microprocessor; B) determining whether impact data varies and where impact data fails to vary, ending, and where impact data varies, adding a time stamp two and a vehicle identification number to the impact data to form second information and storing the second information in memory; C) determining whether a manual lock is in use and: where the manual lock is in use, using the manual lock to retain the second information unchanged in memory; and where a manual lock fails to be in use, using an auto lock to retain the second information unchanged in memory; D) obtaining first information on control events and data and comparing with second information; E) determining whether the first information and the second information is synchronized; F) where the first information and the second information fails to be synchronized, reporting unauthenticated data/tampering; and G) where the first information and second information is synchronized, storing the first information and the second information in memory.
Claim 9
Independent Claim
