Problems solved by technology

[0004] However, because the CPU processing capacity of the vehicle information system is low and the memory is smaller than that of a PC, it is not possible to directly use the antivirus software used by the general PC to perform antivirus on the vehicle information system. and antivirus methods
However, so far, this dedicated vehicle antivirus method has not been proposed and realized.

[0029] As mentioned above, the virus can invade the telematics system through the data content transmitted through the interface of the telematics system (including I / O (such as USB port, DVD port) and wireless network interface), that is, the virus invades the telematics system. The ways mainly include: file interaction of I / O interface, web browsing in wireless network communication, sending and receiving emails in wireless network communication, file and application program download in wireless network communication, etc.

[0030]In this embodiment, the data content transmitted through the interface of the vehicle information system (for example, the file interacted through the I / O interface, the communication content transmitted through the wireless network interface, etc.) is monitored in real time, and the monitored data content It is compared with the virus signature in the virus database to detect whether there is a virus signature in the monitored data content. Once i...

[0057] This embodiment adds a custom anti-virus function on the basis of the first embodiment or the second embodiment, that is, the user can define the scanning mode and the file and / or application program to be scanned in the vehicle information system, and the optional scanning Modes include full scan and quick scan. Once any abnormal situation is found, report and deal with it immediately.

[0058] In order to achieve the above purpose, the vehicle antivirus device 2 according to the third embodiment of the present invention further includes a custom antivirus module 207 . Such as figure 1 As shown, the custom antivirus module 207 further includes a custom module 2071 and a custom scan execution module 2072, wherein the custom module 2071 is, for example, a user interaction interface for the user to define the scanning mode and the information to be scanned in the vehicle information system. Files and / or applications; the custom scan execution module 2072 is configured t...

Abstract

The invention provides a vehicle-mounted antivirus system, which comprises a vehicle-mounted antivirus server for saving and updating a virus database and sending the updated virus database to a vehicle-mounted antivirus device, and the vehicle-mounted antivirus device for monitoring data contents transmitted through the interface of a vehicle-mounted information system in real time, comparing the monitored data contents with virus feature codes in the virus database so as to detect whether the data contents comprise the virus feature codes, clearing the data contents or prompting a user to process the data contents if the virus feature codes are detected from the data contents, and discharging the data contents if the virus feature codes are not detected from the data contents, or for virtually executing the data contents, and determining and processing according to executing action and an executing result. By using the system, the data contents transmitted through the interface of the vehicle-mounted information system can be monitored in real time, so that the aim of performing antivirus on the vehicle-mounted information system is fulfilled.

Description

technical field [0001] The invention relates to the technical field of on-board information processing, in particular to a vehicle-mounted antivirus system and a virus-killing method for antivirus and antivirus of the on-board information system. Background technique [0002] With the development of automobile technology, the market of in-vehicle information system is rapidly heating up. At present, most of the new generation of vehicle information systems integrate the following main functions: ground navigation based on satellite positioning technology (GPS GIS); intelligent transportation based on ITS digital broadcasting (GPS GIS LBS CDMB); based on wireless mobile communication technology (2G / 3G DSRC WLAN) remote information services; and on-board culture and entertainment based on digital broadcasting technology (CDMB-T / CMMB ITS), and of course the business and entertainment functions on the PC. [0003] Vehicle information systems generally have interfaces for data t...
