Electronic proof system based on blockchain, electronic proof storage method and electronic proof file recovery method

Abstract

The invention discloses an electronic proof system based on a blockchain. The electronic proof system comprises a distributed file management system and a consensus network bookkeeping device, whereinthe distributed file management system comprises an attribute basic encryption module, a file segmentation module, a copying and distributing module, a Hass processing module and a sending module, and the consensus network bookkeeping device comprises a consensus network module and a bookkeeping module. The invention also discloses an electronic proof storage method and an electronic proof file recovery method. By use of the electronic proof system based on blockchain, the electronic proof storage method and the electronic proof file recovery method, permission control of a multi-hierarchy relationship can be realized, centralized management can be realized, risks are dispersed, user information can effectively prevent from being leaked, data can not be tampered and can be subjected to tracking traceability, a manual operation can be withdrawn, and information transfer efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a block chain-based electronic certification system and a method for storing certificates and restoring files. Background technique [0002] The traditional electronic certification system mainly has the following characteristics: 1. When the electronic signature production data is used for the electronic signature, it belongs to the electronic signatory; 2. The electronic signature production data is only controlled by the electronic signatory when signing; Any modification of the electronic signature can be found; 4. Any modification of the content and form of the data message after signing can be found, and the parties can also choose to use an electronic signature that meets the reliable conditions agreed upon. [0003] This traditional electronic certification system relies on authoritative third-party agencies to provide services and conduct supervision, su...

Problems solved by technology

[0005] 1. The traditional e-government system has a very high risk of central failure: traditional e-government systems are generally built based on data centers, and any data center has a risk of central failure, including: software errors, viruses, administrator misuse, Natural disasters, computer room failures, etc.; the unavailability or damage of the data center will lead to direct economic losses, stop production, reduce productivity, penalties, lose customers, and also bring negative social effects, decline in customer satisfaction, etc.

[0006] 2. Human error in operation will lead to irreparable errors: Since the traditional e-government system is built based on the data center model, under the highly centralized system, the system needs to pay a lot of labor costs to maintain data security and reliability, but no one is perfect, and people may cause errors in the electronic certification system due to negligence and mistakes, knowledge or skill factors, or even irreparable errors

[0007] 3. The traditional electronic certification system may cause user privacy leakage: the traditional electronic certification system cannot avoid the user's privacy leakage. Since the user's data is stored centrally in the data center of the corresponding node, it is vulnerable to illegal transactions such as hackers. Molecular invasion, stealing user information for information trading

At the same time, problems such as data loss and user privacy information leakage caused by intentional or unintentional management personnel in the data center cannot be avoided.
