Abstract

Provided is a vehicular image processing apparatus for applying a different encryption scheme and access authority for each of a channel and a type of data with respect to an image recorded in a black box mounted in a vehicle, and a data processing method using the same.

Claims

1. A vehicular image processing apparatus mountable in a vehicle, the apparatus comprising:

a camera module to acquire image data corresponding to at least one channel;

a microphone to acquire audio data corresponding to at least one channel; and

a controller, based on a predetermined encryption level of each channel, to generate black box data by encrypting at least one of the image data corresponding to the at least one channel, and the audio data corresponding to the at least one channel.

2. The apparatus of claim 1, wherein the predetermined encryption level is determined for each channel based on a location at which the image data corresponding to the at least one channel and the audio data corresponding to the at least one channel are acquired.

3. The apparatus of claim 1, wherein the controller encrypts at least one of the image data corresponding to the at least one channel and the audio data corresponding to the at least one channel, based on a type of data indicating whether each channel corresponds to an internal area or an external area of the vehicle.

4. The apparatus of claim 1, wherein the controller encrypts internal audio data corresponding to a channel used to acquire a sound occurring in an internal area of the vehicle among the audio data corresponding to the at least one channel.

5. The apparatus of claim 1, wherein the camera module comprises a plurality of cameras corresponding to at least one channel, and

wherein the controller determines whether image data input through each of the plurality of cameras is encrypted, based on a target direction of each of the plurality of cameras corresponding to the at least one channel.

6. The apparatus of claim 1, wherein the predetermined encryption level is determined for each channel based on a publicity identifier corresponding to a purpose of the vehicular image processing apparatus.

7. The apparatus of claim 1, wherein the controller encrypts an audio signal corresponding a predetermined frequency band from the audio data corresponding to the at least one channel.

8. The apparatus of claim 1, wherein the controller encrypts an audio signal corresponding to a portion in which a predetermined word is recognized from the audio data corresponding to the at least one channel through sound recognition.

9. The apparatus of claim 1, wherein, in the predetermined encryption level, an encryption difficulty level is determined based on a data protection level.

10. The apparatus of claim 1, wherein the predetermined encryption level is set such that a channel allowed to be read from the generated black box data is determined based on an authentication level.

11. A data processing method implemented by a vehicular image processing apparatus mountable in a vehicle, the method comprising:

acquiring image data corresponding to at least one channel;

acquiring audio data corresponding to at least one channel; and

generating, based on a predetermined encryption level of each channel, black box data by encrypting at least one of the image data corresponding to the at least one channel, and the audio data corresponding to the at least one channel.

12. The method of claim 11, wherein the predetermined encryption level is determined for each channel based on a location at which the image data corresponding to the at least one channel and the audio data corresponding to the at least one channel are acquired.

13. The method of claim 11, wherein the generating comprises encrypting at least one of the image data corresponding to the at least one channel and the audio data corresponding to the at least one channel, based on a type of data indicating whether each channel corresponds to an internal area or an external area of the vehicle.

14. The method of claim 11, wherein the generating comprises encrypting internal audio data corresponding to a channel used to acquire a sound occurring in an internal area of the vehicle among the audio data corresponding to the at least one channel.

15. The method of claim 11, wherein the generating comprises determining whether image data input using each of a plurality of cameras is to be encrypted, based on a target direction of each of the plurality of cameras corresponding to the at least one channel.

16. The method of claim 11, wherein the predetermined encryption level is determined for each channel based on a publicity identifier corresponding to a purpose of the vehicular image processing apparatus.

17. The method of claim 11, wherein the generating comprises encrypting an audio signal corresponding to a predetermined frequency band from the audio data corresponding to the at least one channel.

18. The method of claim 11, wherein the generating comprises encrypting an audio signal corresponding to a portion in which a predetermined word is recognized from the audio data corresponding to the at least one channel through sound recognition.

19. The method of claim 11, wherein, in the predetermined encryption level, an encryption difficulty level is determined based on a data protection level.

20. The method of claim 11, wherein the predetermined encryption level is set such that a channel allowed to be read from the generated black box data is determined based on an authentication level.
