    摘要： 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.
