Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Such as figure 1 Shown is the method flowchart of a preferred embodiment of the UUID conversion method of the present invention. The UUID is mainly read through S100, and then converted into an EAN-13 barcode (European Article Numbering 13) at step S200. First, in step S110, the universal unique identification code (UUID) of the ARM core board inside the car is obtained through the API interface of the car. The UUID is generated according to the encoding rules of the International Universal Code, including 32-bit hexadecimal numbers. These numbers are arranged in the order of 8-4-4-4-12 or 8-4-4-16. When generating UUID, you need to use the date and time, clock sequence and globally unique IEEE machine identification number that generate UUID. After the above information is processed according to the encoding rules, the UUID is gene...

Abstract

The invention relates to a universally unique identifier (UUID) conversion method for a vehicle-mounted infotainment product. The conversion method comprises the following steps that a UUID is read; the UUID is converted into an EAN-13 barcode. By implementing the UUID conversion method, the complex UUID is converted into the EAN-13 barcode easy to identify; in this way, a user can determine whether the vehicle-mounted infotainment product is a counterfeit product or not according to the EAN-13 barcode imprinted on the vehicle-mounted infotainment product; besides, good query tracking and after-sales service can be provided for the user according to information obtained from the EAN-13 barcode through reverse derivation, and therefore the after-sales service quality of the product is improved.

Description

technical field [0001] The present invention relates to anti-counterfeiting technology, more specifically, relates to a vehicle-machine universal unique identification code conversion method applicable to the vehicle-machine. Background technique [0002] Vehicles are generally installed in today's vehicles, which are used to realize information communication between people and vehicles, and between vehicles and the outside world, such as entertainment, audio and video, car navigation and other functions in the car. During the use of the vehicle, there are often modifications to the vehicle-machine system and replacement of components, resulting in failure of the vehicle-machine system. In order to prevent the car-machine system from being counterfeited, or from car-machine failure due to unauthorized modification, manufacturers generally use the car-machine Universal Unique Identifier (UUID) to determine the originality of the car-machine. However, for ordinary users, It i...
