背景技术Background technique
随着科技发展与生活水平的提高，汽车已经成为人们日常生活工作中常用的代步工具之一。车辆在给人们带来交通的便利，但同时也附带产生了一些其他的麻烦。具体表现为：车辆在使用过程中涉及到车辆的维修保养、所属权变更、保险与理赔以及违规处罚等过程，由于每一个过程都在不同的部门进行(即车辆的维修保养通常在4S店或汽修公司、所属权变更通常在监管部门、保险与理赔通常在保险公司、违规处罚通常在保险公司)，其处理结果的信息也将记录在不同的部门，各信息之间都是分离的，无法进行互联互通。另外，各信息的记录通常都是采用中心化系统，无法避免人为因素的干扰(例如信息的篡改)。由于车辆信息查询不便以及车辆信息存在真实性等因素，容易导致车辆状况评估操作过程复杂且准确度差。例如，目前，二手车交易也日益增加，其中包括线上和线下交易，而二手车交易需要在交易之前对车况进行综合评估来确定是否购买及交易价格，在综合评估内容时需要车辆的维修保养信息、所属权变更信息、保险与理赔信息以及违规处罚信息等。但由于综合评估内容中所需的这些信息存储在不同的部门容易导致交易双方信息不对等，且卖方提供车况信息可能存在缺失、虚假等因素，而买方无法逐一核实卖方出具信息的真实性，导致买方无法对车辆的现状做出正确的评估。With the development of science and technology and the improvement of living standards, automobiles have become one of the means of transportation commonly used in people's daily work. Vehicles bring convenience to people's transportation, but at the same time, they also cause some other troubles. The specific manifestations are: the process of vehicle maintenance, ownership change, insurance and claim settlement, and violation penalties are involved in the process of vehicle use. Since each process is carried out in different departments (that is, vehicle maintenance is usually carried out in 4S shops or Auto repair companies, ownership changes are usually in the regulatory department, insurance and claims are usually in the insurance company, violation penalties are usually in the insurance company), the information on the processing results will also be recorded in different departments, and the information is separated. Unable to communicate with each other. In addition, the recording of each information usually adopts a centralized system, which cannot avoid the interference of human factors (such as tampering of information). Due to factors such as the inconvenience of vehicle information query and the authenticity of vehicle information, the operation process of vehicle condition assessment is easily complicated and the accuracy is poor. For example, at present, second-hand car transactions are also increasing, including online and offline transactions, and second-hand car transactions need to conduct a comprehensive assessment of the condition of the vehicle before the transaction to determine whether to buy and the transaction price, and vehicle maintenance is required during the comprehensive assessment content Maintenance information, ownership change information, insurance and claims information, and violation penalty information, etc. However, because the information required in the comprehensive evaluation content is stored in different departments, it is easy to cause information unequal between the two parties in the transaction, and the vehicle condition information provided by the seller may be missing or false, and the buyer cannot verify the authenticity of the information issued by the seller one by one, resulting in The buyer cannot make a proper assessment of the current condition of the vehicle.
