Abstract

A driving recorder system, which enables realizing easy-to-use handling of recorded data, excellent impact resistance and high security with no superfluous operations, includes a driving recorder for recording vehicle driving information and a reproducing apparatus for reproducing the vehicle driving information recorded in the driving recorder. The driving recorder has an encryption apparatus for encrypting the vehicle driving information by using a public key, and a first optical disc apparatus for continuously recording the vehicle driving information encrypted thereby into an optical disc. The reproducing apparatus has a second optical disc for reproducing the vehicle driving information recorded in the optical disc, and a decryption apparatus for decrypting the vehicle driving information reproduced thereby by using a secret key corresponding to the public key. It is featured that the encryption apparatus performs encrypting by using a public key recorded in the optical disc in advance.

Claims

1. A driving recorder, comprising:

an encryption apparatus configured to encrypt vehicle driving information using a public key; and

an optical disc apparatus configured to continuously record the encrypted vehicle driving information onto an optical disc,

wherein the public key is pre-recorded to the optical disc.

2. The driving recorder according to claim 1, further comprising a memory recording apparatus for configured to continuously record the vehicle driving information to a nonvolatile memory in conjunction with recording of the vehicle driving information onto the optical disc.

3. The driving recorder according to claim 1, wherein the optical disc is a write-once optical disc.

4. A driving recorder system, comprising:

a driving recorder for recording vehicle driving information; and

a reproducing apparatus for reproducing the vehicle driving information recorded in the driving recorder,

wherein the driving recorder comprises an encryption apparatus configured to encrypt the vehicle driving information using a public key, and a first optical disc apparatus configured to continuously record the vehicle driving information onto an optical disc,

wherein the reproducing apparatus comprises a second optical disc apparatus configured to reproduce the vehicle driving information recorded onto the optical disc, and a decryption apparatus configured to decrypt the vehicle driving information reproduced thereby using a secret key corresponding to the public key, and

wherein the public key is pre-recorded to the optical disc.

5. The driving recorder system according to claim 4, wherein the driving recorder further comprises a memory recording apparatus configured to continuously record the vehicle driving information to a nonvolatile memory in conjunction with recording of the vehicle driving information onto the optical disc, and wherein the reproducing apparatus further comprises a memory reproducing apparatus configured to reproduce the vehicle driving information recorded to the nonvolatile memory.

6. The driving recorder system according to claim 4, wherein the optical disc is a write-once optical disc.

7. A recording and reproducing method for a driving recorder system, comprising the steps of:

encrypting vehicle driving information using a public key;

continuously recording the vehicle driving information onto an optical disc;

reproducing the vehicle driving information recorded onto the optical disc; and

decrypting the vehicle driving information using a secret key corresponding to the public key,

wherein the encryption is performed using a public key pre-recorded onto the optical disc.

8. The recording and reproducing method according to claim 7, further comprising the steps of:

continuously recording the vehicle driving information to a nonvolatile memory in conjunction with recording of the vehicle driving information onto the optical disc; and

reproducing the vehicle driving information recorded in the nonvolatile memory.

9. The recording and reproducing method according to claim 7, wherein the optical disc is a write-once optical disc.
