Drawings
FIG. 1 is a system architecture diagram of the present invention;
fig. 2 is a system composition topology of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
The signing system of the electric power material supply electronic document based on the block chain deposit certificate comprises a network layer, a block chain layer and a business application layer, wherein a CA management system penetrates through the block chain layer and the business application layer, and the structures of all the components are shown in figure 1.
The CA management system is responsible for access management of users, registration data submitted by the users pass cross comparison and verification with internal data of the power enterprises such as ERP, e-commerce platform and the like, then digital certificates are issued in an authorized mode, and operation authorization codes are distributed to the users. The block chain data interface authority management is responsible for verifying the user identity and the operation authority, and the authority comprises interfaces such as electronic document generation, document information retrieval, electronic signature interface, information archiving and authorized information retrieval. Various services signed by the electronic document in the power material supply fulfillment can be realized through the calling of each interface, the interface authority must be authorized to use through CA management, and unauthorized users cannot acquire or operate corresponding data. The intelligent contract and the consensus algorithm are the core of the block chain layer, each node needs to perform corresponding operation according to the intelligent contract conditions and the consensus algorithm which are agreed in advance, and multi-party signature and signature of various documents (a goods acceptance bill, a delivery bill and a quality insurance bill) in the electric power material supply performance are realized by means of the intelligent contract and the consensus algorithm.
When the system is deployed in a specific implementation manner, as shown in fig. 2, the functions of the service platforms are basically the same and play a role in the front-end, but the user objects are different. Because the objects related to the power material supply service include suppliers, construction units, project construction units, supervision units and material management units, a preposed service platform is arranged for each different object, the purpose is to ensure that data are not interfered with each other and operation reliability is increased, the purpose is to relieve network flow pressure, the purpose is to carry out data butt joint with service systems of different units along with the application of the system, and the purpose of designing the preposed service platform is to meet the requirement of data butt joint expansion. The block chain node is a main node of the block chain part of the whole system, is responsible for executing a consensus algorithm and an intelligent contract, and realizes distributed storage of data so as to realize the aim of decentralization. The user sends requests such as inquiry and document signing through the mobile phone APP, and then sends the requests to the service platform, the service platform interacts with the block chain system through an interface mode, whether the authority of the mobile phone user is an authorized user is firstly checked, if the authority is the authorized user, information is returned to the user, otherwise the request is rejected, and the user needs to encrypt data by using a key of the user in the electronic document signing process. And the block chain system records corresponding information and adds a time stamp after receiving the legal request, and then writes the information into the block chain for storage.
Since blockchain technology has non-tamper-able and certain rights, the technology itself can solve the trust problem in principle. However, in order to ensure the credibility of system data, the data storage has more public credibility, a third-party node of a public certificate place or an arbitration mechanism is introduced into the whole system, once data disputes occur among users, the users can submit the stored electronic documents to the public certificate place or the arbitration mechanism for information verification, the public certificate place or the arbitration mechanism takes out key node information during signing of the electronic documents from a block chain according to the information submitted by the users, then the key node information is decrypted through a secret key provided by the users to obtain detailed information of the electronic documents, whether the document information is falsified can be confirmed by comparing the electronic document information submitted by the users, and the signing behaviors of the users are confirmed according to each flow information and the occurring time stamps in the signing process.
The signing method of the electric power material supply electronic document based on the block chain deposit certificate comprises the following steps:
step 1: identity confirmation is carried out in a mode of real-name authentication and legal documents, and hands are used for firstly agreeing to the terms of the system, and then relevant registration materials are submitted and authorized single-piece stamp styles are submitted. (ii) a
Step 2: the system audits the registration material, and after auditing, issues a registration certificate and distributes an authorization code.
And step 3: each user signs the electronic document according to the project information, the system electrically stores the information and the operation time of each key node signed by the user and records the information and the operation time to the block chain certificate storage platform, and the key nodes comprise user identity authentication information, flow information in the electronic document signing process, user certificate information and the like.
And 4, step 4: the notarization department or other presidential mechanisms can take out the information from the block link points, and then decrypt the information through the secret key to obtain the electronic document information to notarize the information.
The step 1 comprises the following steps:
step 101, the user agrees to the terms of use of the system.
102, the user registers in real name through a mobile phone APP, and submits registration information including a registrant identity card, a mobile phone number, a unit business license copy, a unit legal identity card and a single official seal style.
And 2, the system performs cross check on the registration information through relevant information acquired from an ERP system in the power enterprise and an e-commerce platform system in the power enterprise, and automatically distributes a registration certificate and a signature operation authorization code after the check is qualified.
In step 3, a system user signs an electronic document in the power material supply through a mobile phone APP, inputs an operation authorization code in the signing process to confirm the right and stores the flow information of a key node, uploads the information to a block chain node through a system service platform, encrypts the information through a user key and finally stores the information in the block chain, and the electronic document of the power material supply service related in the process comprises: receiving, checking and accepting, delivering and guaranteeing; the key node flow information involved in the signing process comprises the following steps:
registration information: the name of the user unit, the legal person, the identity card number of the registrant, the identity card number of the legal person proxy, the unified social credit code of the user unit and the timestamp.
User operation information:
