Abstract

Disclosed herein is a method for collecting, by a vehicle information collection apparatus, vehicle accident information. The method includes receiving vehicle accident information including impact detection time information and location information from a plurality of vehicle communication terminals, determining whether a vehicle accident has occurred based on the received vehicle accident information, requesting a vehicle communication terminal which belongs to the plurality of vehicle communication terminals and which is related to the vehicle accident to send accident information based on a result of the determination, receiving encrypted image data related to the vehicle accident from the vehicle communication terminal related to the vehicle accident in response to the request, and decoding the received image data and storing the decoded image data along with the vehicle accident information.

Claims

1. A method for collecting, by a vehicle accident information collection apparatus, vehicle accident information, the method comprising:

receiving vehicle accident information comprising impact detection time information and location information from a plurality of vehicle communication terminals;

determining whether a vehicle accident has occurred based on the received vehicle accident information;

requesting a first vehicle communication terminal which belongs to the plurality of vehicle communication terminals and which is related to the vehicle accident to send accident information based on a result of the determination;

receiving encrypted image data related to the vehicle accident from the vehicle communication terminal related to the vehicle accident in response to the request; and

decoding the received image data and storing the decoded image data along with the vehicle accident information.

2. The method of claim 1, wherein determining whether the vehicle accident has occurred based on the received vehicle accident information comprises:

determining whether the vehicle accident information comprising the impact detection time information and the location information included within a predetermined threshold time and distance range is plural; and

determining that the vehicle accident has occurred when it is determined that the vehicle accident information is plural.

3. The method of claim 1, further comprising:

specifying a terminal which has sent information as the first vehicle communication terminal based on information on a reception time of the vehicle accident information and a location information of the vehicle accident information when it is determined that the vehicle accident has occurred;

sending a device authentication request to the specified vehicle communication terminal related to the vehicle accident;

receiving authentication information transmitted by the first vehicle communication terminal in response to the device authentication request; and

authenticating the first vehicle communication terminal by decoding the received authentication information.

4. The method of claim 3, wherein:

a public key value is previously shared with the first vehicle communication terminal for device authentication, and

when a server access request and a device-unique number are received from the first vehicle communication terminal, a random number is generated and transmitted to the first vehicle communication terminal.

5. The method of claim 4, wherein:

when information obtained by encrypting the device-unique number, the random number, and a server IP value transmitted by the first vehicle communication terminal, using a personal key value is received,

decoding the received information using the public key value, verifying the decoded information, and

notifying a permission of transmission of image data to the first vehicle communication terminal.

6. The method of claim 1, further comprising:

searching whether a surrounding terminal is within a specific distance from the first vehicle communication terminal at the vehicle accident location and time when it is determined that the vehicle accident has occurred; and

requesting image data related to the vehicle accident to the surrounding terminal when the retrieved surrounding terminal is found.

7. The method of claim 1, further comprising:

receiving integrity verification information along with the encrypted image data related to the vehicle accident received in response to the request, and

decoding the encrypted image data using the integrity verification information.

8. The method of claim 7, wherein the integrity verification information comprises:

a message authentication code (MAC) tag value generated through hash operation based on a header representative of the image data, and

a time stamp value of a point of time at which the image data is transmitted.

9. The method of claim 8, wherein:

by calculating a time lag between a time stamp value attached to the MAC tag value and a time stamp value of a point of time at which the image data is received, integrity of the image data is verified by determining whether the time lag is within a permissible range.

10. A vehicle accident information collection apparatus, comprising:

a vehicle accident information reception unit configured to receive vehicle accident information comprising impact detection time information and location information from a plurality of vehicle communication terminals;

an accident determination unit configured to determine whether a vehicle accident has occurred based on the received vehicle accident information;

an information request unit configured to request a first vehicle communication terminal which belongs to the plurality of vehicle communication terminals and which is related to the vehicle accident to send accident information based on a result of the determination;

a decoding unit configured to decode encrypted image data related to the vehicle accident, which is received in response to the request; and

a storage unit configured to store the decoded image data along with the vehicle accident information.

11. A method for sending, by a vehicle communication terminal, vehicle accident information to a vehicle information collection apparatus, the method comprising:

receiving an impact detection signal of a specific strength or more from a sensor within a vehicle;

generating vehicle accident information based on impact detection time information and location information included in the received impact detection signal;

sending the generated vehicle accident information to the vehicle information collection apparatus;

receiving an accident information transmission request based on a result of a determination of whether a vehicle accident has occurred by the vehicle information collection apparatus;

encrypting image data related to the vehicle accident in response to the request; and

sending the encrypted image data to the vehicle information collection apparatus.

12. The method of claim 11, further comprising:

receiving access barring information from a base station;

selecting a specific random number in response to the access barring information; and

sending the selected random number to the base station,

wherein the base station compares the selected random number with a probability value of the access barring information and permits random access when the selected random number is lower than the probability value.

13. The method of claim 12, wherein the specific random number is selected in one of periods divided based on an amount of impact.

14. The method of claim 13, wherein the periods divided based on the amount of impact have different access priorities.

15. The method of claim 11, further comprising receiving a device authentication request from the vehicle information collection apparatus when the vehicle accident is determined to have occurred on a result of the determination of the vehicle information collection apparatus.

16. The method of claim 15, further comprising:

sending a server access request and a device-unique number in response to the device authentication request,

encrypting the device-unique number, a random number, and a server IP value using a personal key when the random number is received from the vehicle information collection apparatus, and

sending the encrypted device-unique number, random number, and server IP value to the vehicle information collection apparatus.

17. The method of claim 11, further comprising:

encrypting the image data related to the vehicle accident using a masking scheme in response to the accident information transmission request, and

sending the encrypted image data to the vehicle information collection apparatus.

18. The method of claim 17, further comprising sending integrity verification information along with the encrypted image data,
