Fig. 1 is a flowchart of a vehicle-mounted terminal program verification method according to an embodiment of the present invention, where an embodiment of the present invention specifically includes the following steps:
step S101, when a program updating event is detected, checking an information source triggering the program updating event, and receiving an updating program under the condition that the information source is successfully checked.
In one embodiment, the program of the vehicle-mounted terminal verifies the updating program in the updating process. The program update event may be triggered by receiving an update instruction issued by an information source. Before installing and updating the updating program, firstly, verifying an information source triggering a program updating event, and receiving the updating program under the condition that the information source is successfully verified.

step S1011, obtaining an information source identifier recorded during program installation, where the information source identifier is determined to be obtained based on multiple different vehicle-mounted terminals during program installation.
The program installation is the installation of the original program before the current updated program, and the information source identifier is correspondingly recorded during the installation, wherein the information source identifier can be a server address, a unique identifier provided by a software provider and the like. When recording the information source identifier, the information source identifier is determined based on the program installation of a plurality of different vehicle-mounted terminals, namely the information source identifier is determined not according to the current installation situation of the terminal but based on the situations of the plurality of vehicle-mounted terminals.

Step S104, a second check identifier recorded in advance in the auxiliary check terminal is obtained, and whether the check of the program update event is successful is determined based on a comparison result of the first check identifier and the second check identifier.
In one embodiment, after the auxiliary verification terminal is determined, a second verification identifier pre-recorded by the auxiliary verification terminal is acquired, and whether verification of the program update event is successful is determined based on a comparison result of the first verification identifier and the second verification identifier. The second check mark is generated when the auxiliary check terminal performs corresponding updating procedures, and the generation mode of the second check mark can refer to the generation mode of the first check mark of the current terminal.
Optionally, the comparison process of the verification identifier may be: and analyzing the second check identification to obtain a comparison program size, a comparison characteristic character string and a comparison time stamp, and determining that the check is successful under the condition that the comparison program size and the comparison characteristic character string are consistent with the program size and the check character string recorded by the first check identification, and the difference between the comparison time stamp and the time stamp recorded by the first check identification meets the time threshold. Wherein, the time threshold value can use different set values, such as 30 minutes or 1 hour.
