Abstract: Method and device for vehicle-borne payment are provided A vehicle-borne payment request sent by a vehicle is received and includes vehicle identification information. According to the vehicle identification information, after the vehicle is determined as a registered vehicle, driving attribute data of the vehicle within a current time period, and a vehicle driving strategy of the vehicle are acquired. According to the driving attribute data in the current time period, and the vehicle driving strategy, a risk level corresponding to the vehicle-borne payment request is determined. The risk level is transmitted to a transaction platform so that the transaction platform determines whether to make a payment according to the risk level. The vehicle driving strategies are created after the vehicle applies for registration, according to driving attribute data within a preset time period.

Abstract: A security electronic file processing method based on a block chain structure is proposed by the present disclosure, including: constructing a security electronic file generation request based on an occurrence of a trigger event by a member node in a block chain formed by a master node and at least one member node, and transmitting the security electronic file generation request to the master node, wherein the master node and each of the at least one member node, each as independent block respectively, are connected to each other; generating a security electronic file by the master node based on the received security electronic file generation request, and transmitting the generated security electronic file to the member node specified by the security electronic file generation request; and performing operations on the security electronic file by any of the at least one member node after receiving the security electronic file by performing data communication with another member node.
