Abstract

Disclosed are a method and an apparatus for verifying times and locations of image data of cameras for vehicles. The method for verifying times and locations of image data of cameras for vehicles includes anonymously receiving digests including locations and times of data created by cameras for a plurality of vehicles, respectively, forming a mesh structure by bi-directionally connecting the cameras for the plurality of vehicles to cameras for adjacent vehicles, based on a relationship between the received digests, and if the mesh structure is formed, verifying times and locations for the digests constituting the mesh structure based on the formed mesh structure.

Claims

1. A method for verifying times and locations of image data of cameras for vehicles, the method comprising:

anonymously receiving digests including locations and times of data created by cameras for a plurality of vehicles, respectively;

forming a mesh structure by bi-directionally connecting the cameras for the plurality of vehicles to cameras for adjacent vehicles, based on a relationship between the received digests; and

if the mesh structure is formed, verifying times and locations for the digests constituting the mesh structure based on the formed mesh structure.

2. The method of claim 1, wherein the receiving of the digests includes:

receiving a digest of a camera for a host vehicle and the digests received from cameras for adjacent surrounding cameras from the cameras for the plurality of vehicles, by broadcasting the digests of the data created by the cameras for the plurality of vehicles to the cameras for the adjacent surrounding vehicles and by receiving digests broadcast from the cameras for the surrounding vehicles

3. The method of claim 1, wherein the receiving of the digests includes:

anonymously receiving the digests from the cameras for the plurality of vehicles, by changing predetermined numbers of first bits of digest messages to source MAC addresses of the cameras of the plurality of vehicles by the cameras of the plurality of vehicles.

4. The method of claim 1, wherein the forming of the mesh structure includes:

forming the mesh structure, by searching for a predetermined trusted digest, of the received digests, which is closest to a preset location and by creating an edge between bi-directional adjacent digests by using the discovered trusted digest and the digests corresponding to the preset location.

5. The method of claim 4, wherein the verifying of the times and the locations includes:

verifying the times and the locations for the digests corresponding to the preset location, by evaluating trust scores for the digests corresponding to the preset location based on a trust score of the trusted digest and by determining legitimacies of the digests corresponding to the preset location based on the evaluated trust score.

6. The method of claim 2, wherein the verifying of the times and the locations includes:

verifying the times and the locations for the digests corresponding to the preset location, by determining participations of the digests constituting the mesh structure by exchange of digests with the cameras for the surrounding vehicles and by determining a digest that participates by the exchange of the digests as a legitimate digest.

7. A system for verifying times and locations of image data of cameras for vehicles, the system comprising:

cameras for a plurality of vehicles configured to create digests including locations and times of data, transmitting the created digests to cameras for surrounding vehicles, receiving digests transmitted from the cameras for the surrounding vehicles, and uploading a digest of a camera for a host vehicle and the received digests; and

a server configured to anonymously receive digests that are uploaded by the cameras for the plurality of vehicles, form a mesh structure by bi-directionally connecting the cameras for the plurality of vehicles to cameras for adjacent vehicles based on a relationship between the received digests, and verify times and locations for the digests constituting the mesh structure based on the formed mesh structure.

8. An apparatus for verifying times and locations of image data of cameras for vehicles, the apparatus comprising:

a reception unit configured to anonymously receive digests including locations and times of data created by cameras for a plurality of vehicles, respectively;

a formation unit configured to form a mesh structure by bi-directionally connecting the cameras for the plurality of vehicles to cameras for adjacent vehicles, based on a relationship between the received digests; and

a verification unit configured to, if the mesh structure is formed, verify times and locations for the digests constituting the mesh structure based on the formed mesh structure.

9. The apparatus of claim 8, wherein the reception unit receives a digest of a camera for a host vehicle and the digests received from cameras for adjacent surrounding vehicles from the cameras for the plurality of cameras, by broadcasting the digests of the data created by the cameras for the plurality of vehicles to the cameras for the adjacent surrounding vehicles and by receiving digests broadcast from the cameras for the surrounding vehicles.

10. The apparatus of claim 8, wherein the reception unit anonymously receives the digests from the cameras for the plurality of vehicles, which are obtained by changing predetermined numbers of first bits of digest messages to source MAC addresses of the cameras of the plurality of vehicles by the cameras of the plurality of vehicles.

11. The apparatus of claim 8, wherein the formation unit forms the mesh structure, by searching for a predetermined trusted digest, of the received digests, which is closest to a preset location and by creating an edge between bi-directional adjacent digests by using the discovered trusted digest and the digests corresponding to the preset location.

12. The apparatus of claim 11, wherein the verification unit verifies the times and the locations for the digests corresponding to the preset location, by evaluating trust scores for the digests corresponding to the preset location based on a trust score of the trusted digest and by determining legitimacies of the digests corresponding to the preset location based on the evaluated trust score.

13. The apparatus of claim 9, wherein the verification unit verifies the times and the locations for the digests corresponding to the preset location, by determining participations of the digests constituting the mesh structure by exchange of digests with the cameras for the surrounding vehicles and by determining a digest that participates by the exchange of the digests as a legitimate digest.

14. A method for verifying times and locations of image data of cameras for vehicles, the method comprising:

anonymously receiving profiles including locations and times of data created by cameras for a plurality of vehicles, respectively;

forming a map structure by bi-directionally connecting the cameras for the plurality of vehicles to cameras for adjacent vehicles, based on a relationship between the received profiles; and

if the map structure is formed, verifying times and locations for the profiles constituting the map structure based on the formed map structure.

15. The method of claim 14, wherein the profiles include digests that are hash values in unit of a specific time.
