Embodiment Construction

[0062] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0063] As the underlying implementation technology of the Bitcoin system, the blockchain is used to record the history of Bitcoin transactions. The blockchain data has a time stamp, and the consensus mechanism is used to enable nodes to verify and record together. It is non-tamperable and unforgeable. One of the most trustworthy data storage methods in existence, blockchain is widely used in various data notarization and auditing scenarios.

[0064] Due to the technical advantages of decentralized management and non-tamperable pr...

Abstract

The invention provides a method for guaranteeing the authenticity of electronic files based on a block chain, which comprises the following steps: establishing a system overall structure, wherein thesystem overall structure comprises: each service system embedding, an access layer, a block chain network and a management platform; Establishing the system operation process, including: establishingthe business department, software development kit SDK, authentication center and the interaction between the block chain nodes running process; On the basis of the overall construction of the established system, combined with the operation process of the system, establishing the authenticity verification process of electronic documents. The invention utilizes the technical advantages of decentralization of the block chain and non-tampering of the process record, introduces the block chain technology into the electronic file authenticity research field and the application in practice, and realizes the functional advantages of flatness, credibility and security of the block chain.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method for ensuring the authenticity of electronic documents based on block chains. Background technique [0002] First of all, with the popularity of random computers and the Internet, electronic documents have gradually replaced paper documents and become the main medium for office communication. Most of the existing research on the method system and practice of electronic document authenticity guarantee focuses on the discussion and suggestions of management systems, laws and regulations, and there are few method systems combined with information means. [0003] Each key business process in the whole process of electronic document life cycle is the risk node of its authenticity guarantee. The whole process of electronic document life cycle usually includes the following key stages: [0004] (1) The electronic document production stage mainly includes key business proc...
