Description
Technical Field
The application relates to the field of block chain technology application, in particular to an ETC invoice management method, equipment and medium based on a block chain.
Background
With the improvement of Electronic Toll Collection (ETC) technology, Toll gates of expressways, tunnels and bridges in China and even in the world are beginning to be applied and even popularized with ETC charging modes. By using the ETC charging mode, vehicles can be allowed to pass at high speed (dozens of kilometers or more than 100 kilometers), and the traffic capacity of the highway is greatly improved; the highway charging is electronic, so that the management cost and the labor cost of charging can be reduced; meanwhile, the noise level and the exhaust emission of the toll gate can be greatly reduced; the traffic capacity is greatly improved, so that the scale of the toll station can be reduced, and the capital construction cost and the management cost are saved.
Meanwhile, when an operation type vehicle such as a taxi passes through a toll station, a passenger usually needs to obtain a toll invoice of a highway or a bridge tunnel for storage. Although electronic invoices can be issued using the ETC system as well, the electronic invoices can only be issued to the vehicle holder and cannot be provided for use by passengers. This results in that, even if the ETC device is installed, a commercial vehicle that could pass through the ETC lane originally cannot pass through the ETC lane directly because of the need to ask for a paper invoice, and the invoice must be asked for from a manual lane. Under the large environment that ETC is constantly popularized, the number of artificial lanes is less and less, only one to two artificial toll lanes are arranged at the entrance and exit of most of expressways or bridge tunnels, and a large number of large trucks need to be weighed and checked through the artificial lanes. Therefore, when commercial vehicles such as taxis pass through the manual toll gate, long-time waiting is often needed, the passing efficiency of the vehicles is reduced, and great troubles are brought to drivers and passengers of the vehicles.
Therefore, at present, there is an urgent need to develop a novel management method for an ETC invoice, which can be set to be issued to other passengers when issuing an ETC passing invoice, and has solved the problem of low vehicle passing efficiency on the existing highway.

In this embodiment, the ETC invoice management method based on the block chain further includes acquiring an invoice use application sent by the ticket-receiver side, verifying the owner information of the electronic invoice again in response to the invoice use application, and if the owner information is consistent with the identity information of the ticket-receiver side, automatically sending the electronic invoice to the reserved address of the ticket-receiver side based on the intelligent contract. The invoice use application comprises an electronic signature generated by a receipt party end by adopting a private key; and verifying the electronic signature in the invoice use application by adopting the public key, and if the verification is successful, allowing the electronic invoice to be sent to a reserved address of the invoice receiver. Through the digital signature technology, the invoice using process is guaranteed to be executed by the current owner of the invoice in an agreeable mode, and meanwhile the invoice can be effectively guaranteed not to be used for the second time by changing the using state of the invoice.
In this embodiment, the ETC invoice management method based on the block chain further comprises the steps of setting the invoice use state as unused when the electronic invoice is generated based on the intelligent contract; responding to the invoice transfer application to verify whether the invoice use state is unused, and if so, allowing to change the attribution person information of the electronic invoice; responding the invoice use application to verify whether the invoice use state is unused again, and if so, allowing the electronic invoice to be sent to a reserved address of the invoice receiver; based on the intelligent contract, the electronic invoice is sent to the reserved address of the invoice receiving side, and then the invoice using state of the electronic invoice is changed into used invoice. The invoice use state is set to be unused when the invoice is generated, the invoice can be verified when the electronic invoice ownership is transferred or the invoice is used, and the invoice is prevented from being used or stolen, so that the invoice transferee is prevented from being lost.
In this embodiment, the method for managing the ETC invoice based on the block chain further includes acquiring an identity registration application sent by the user side, where the identity registration application at least includes identity information and an account number of the user side; based on an intelligent contract, generating a pair of public key and private key by adopting an asymmetric encryption algorithm according to the identity registration application; associating the public key with an account number of a user side, and uploading the public key to an ETC invoice management block chain; and sending the private key to the user side. The public key can be used to verify the identity of the user terminal, and the private key can be used to generate an electronic signature of the user terminal.
In addition, the ETC invoice management method based on the block chain further comprises the steps of obtaining an invoice management application, and managing the electronic invoices stored in the ETC invoice management block chain according to the invoice management application.

In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.
The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.
Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
