Abstract

A method, system and computer program product for wireless communication between vehicles are provided. In the method, identification information of a first vehicle by a second vehicle being spatially close to the first vehicle is obtained. And a first key associated with the first vehicle by using the identification information is acquired. Data originated from the first vehicle and signed with a second key corresponding to the first key are identified with the first key. And then the identified data is processed.

First claim

What is claimed is:

1. A method comprising:
obtaining a plurality of identification information of a specified first vehicle by a second vehicle, including a hash value, the second vehicle being in a linear spatial relationship with, but not directly behind, the first vehicle, wherein the second vehicle is unable to capture an image of the first vehicle by a camera on the second vehicle directly;
transmitting, by the first vehicle, a plurality of neighboring vehicle information, including a plurality of neighboring vehicle hash values and a plurality of neighboring vehicle digital signatures;
acquiring a first key associated with the first vehicle based on the obtained identification information;
identifying a plurality of first vehicle data based on the first key, the first vehicle data being signed with a second key corresponding to the first key; and
processing the identified plurality of first vehicle data, wherein the plurality of first vehicle data is first video data captured by an in-vehicle camera in the first vehicle.

2. The method of claim 1 , wherein the first key and the second key are a public key and a private key, respectively, of an asymmetric key pair assigned to the first vehicle.

3. The method of claim 1 , wherein processing the identified plurality of first vehicle data further comprises displaying the captured first video data in the second vehicle.

4. The method of claim 1 , wherein processing the identified plurality of first vehicle data further comprises:
obtaining a plurality of second video data captured by a camera in the second vehicle and a plurality of third video data captured by a camera in a third vehicle, wherein the first vehicle, the second vehicle, and the third vehicle are moving on a road in a linear spatial relationship;
combining the identified plurality of first video data with the obtained plurality of second video data and the obtained plurality of third video data into combined video data; and
displaying the combined video data.

5. The method of claim 1 , wherein obtaining a plurality of identification information of the first vehicle by the second vehicle, the second vehicle being in a linear spatial relationship with the first vehicle further comprises:
obtaining an image of the first vehicle; and
identifying the plurality of identification information of the first vehicle based on the obtained image.

6. The method of claim 5 , wherein the obtained image of the first vehicle is captured by a camera in the second vehicle or by a camera in a third vehicle being spatially close to the first vehicle.

7. The method of claim 1 , wherein the plurality of identification information is a license plate number of the first vehicle.

8. The method of claim 1 , wherein processing the identified plurality of first vehicle data further comprises:
signing the plurality of identification information with a third key associated with the second vehicle; and
transmitting the signed plurality of identification information to a third vehicle.

9. A computer system comprising:
one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising;
obtaining a plurality of identification information of a specified first vehicle by a second vehicle, including a hash value, the second vehicle being in a linear spatial relationship with, but not directly behind, the first vehicle, wherein the second vehicle is unable to capture an image of the first vehicle by a camera on the second vehicle directly;
transmitting, by the first vehicle, a plurality of neighboring vehicle information, including a plurality of neighboring vehicle hash values and a plurality of neighboring vehicle digital signatures;
acquiring a first key associated with the first vehicle based on the obtained identification information;
identifying a plurality of first vehicle data based on the first key, the first vehicle data being signed with a second key corresponding to the first key; and
processing the identified plurality of first vehicle data, wherein the plurality of first vehicle data is first video data captured by an in-vehicle camera in the first vehicle.

10. The computer system of claim 9 , wherein the first key and the second key are a public key and a private key, respectively, of an asymmetric key pair assigned to the first vehicle.

11. The computer system of claim 9 , wherein processing the identified plurality of first vehicle data further comprises:
obtaining a plurality of second video data captured by a camera in the second vehicle and a plurality of third video data captured by a camera in a third vehicle, wherein the first vehicle, the second vehicle, and the third vehicle are moving on a road in a linear spatial relationship;
combining the identified plurality of first video data with the obtained plurality of second video data and the obtained plurality of third video data into combined video data; and
displaying the combined video data.

12. The computer system of claim 9 , wherein obtaining a plurality of identification information of the first vehicle by the second vehicle, the second vehicle being in a linear spatial relationship with the first vehicle further comprises:
obtaining an image of the first vehicle; and
identifying the plurality of identification information of the first vehicle based on the obtained image.

13. The computer system of claim 12 , wherein the obtained image of the first vehicle is captured by a camera in the second vehicle or by a camera in a third vehicle being spatially close to the first vehicle.

14. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions readable by a device to cause the device to perform a method comprising:
obtaining a plurality of identification information of a specified first vehicle by a second vehicle, including a hash value, the second vehicle being in a linear spatial relationship with, but not directly behind, the first vehicle, wherein the second vehicle is unable to capture an image of the first vehicle by a camera on the second vehicle directly;
transmitting, by the first vehicle, a plurality of neighboring vehicle information, including a plurality of neighboring vehicle hash values and a plurality of neighboring vehicle digital signatures;
acquiring a first key associated with the first vehicle based on the obtained identification information;
identifying a plurality of first vehicle data based on the first key, the first vehicle data being signed with a second key corresponding to the first key; and
processing the identified plurality of first vehicle data, wherein the plurality of first vehicle data is first video data captured by an in-vehicle camera in the first vehicle.

15. The computer program product of claim 14 , wherein the first key and the second key are a public key and a private key, respectively, of an asymmetric key pair assigned to the first vehicle.

16. The computer program product of claim 14 , wherein the plurality of first vehicle data is first video data captured by a camera in the first vehicle.

17. The computer program product of claim 14 , wherein obtaining a plurality
