Driving recorder and method for data protection and identification

Abstract

The invention provides a driving recorder. The driving recorder comprises a sound and video collecting module for collecting sound and video raw data, a data memory module, a display module, a positioning system module and a safety chip, wherein the positioning system module is used for generating positioning information raw data; an asymmetrical secret key signature algorithm, an asymmetrical secret key verification and signature algorithm, private key data and public key data are preset in the safety chip; the safety chip enables the sound and video raw data and the positioning information raw data to generate a data abstract, and generates a data signature through the asymmetrical secret key signature algorithm; the data memory module enables the sound and video raw data, the positioning information raw data and the data signature to be jointly stored in a driving recorder data file. The invention further provides a method for data protection and identification of the driving recorder. Compared with the correlation technique, the driving recorder and the method for data protection and identification of the driving recorder are high in protection intensity for data, and the data is not liable to falsify, so that the reliability is high.

Description

【Technical field】 [0001] The invention relates to the data storage field of a driving recorder, in particular to a driving recorder and a data protection and identification method thereof. 【Background technique】 [0002] With the development of the economy, the number of cars is increasing, and the traffic accidents are also increasing. In order to facilitate the reproduction of traffic accidents and the identification of responsibilities, the use of driving recorders is becoming more and more popular. [0003] However, the data (including video, audio, location information, etc.) of the driving recorder in the related art is stored in the device in plain text and without verification, and is easy to be maliciously tampered with. In some cases, the content of the tampered driving recorder will seriously affect its legitimacy and persuasiveness as evidence. Not only that, tampering with the data of the driving recorder for the purpose of fraudulent insurance will also bring ...
