Embodiment 1

[0048] This embodiment elaborates in detail the flow of the "Blockchain-based Internet financial electronic data preservation system and method" of the present invention in the case of using the Ethereum blockchain network in a real network environment.

[0049] figure 1 It is a schematic diagram of the system architecture based on the system and method of the present invention. From figure 1 It can be seen from the figure that the system is divided into five modules: WEB client, J2EE application server, file server, database storage and blockchain storage, and each module includes the following parts:

[0050] Module A: WEB client, the only interface for the user to interact with the system, receives the data and requests submitted by the user, and displays the data returned by the server;

[0051] Module B: The core application server of the system, which organizes various logical operations and module calls, specifically:

[0052] Module B.1: Business module, built on th...

Abstract

The invention provides a blockchain-based Internet financial electronic data security system and method, and belongs to the fields of computer application technologies and blockchain network application technologies. A user submits Internet financial electronic data, an original data file is stored in a file server, the storage location and data content of the data file are encrypted through a modern cryptography technology, and a Harsh value of the data file and the encrypted data are stored in an Ethereum blockchain transaction; and when originality verification is conducted, the Harsh value is read from the blockchain transaction, and a Harsh value of a to-be-verified file is calculated and compared with the Harsh value. By using the Ethereum blockchain network, the security requirements of most data types can be met, the storage process can be transparentized, and the conditions that the data is lost, and the stored data is tampered can be avoided; and the security data is encrypted through the modern cryptography technology, and therefore the condition that the privacy data is embezzled by plaintext is avoided.

Description

technical field [0001] The invention relates to an Internet financial electronic data preservation system, in particular to a blockchain-based Internet financial electronic data preservation system, and belongs to the fields of computer application technology and blockchain network application technology. Background technique [0002] In the Internet age, financial technology is developing rapidly, and traditional finance, information, and the Internet are merging at an accelerated rate, and tend to be more digitized. Finance is no longer just the literal meaning of financial intermediation, but a high degree of integration of information and technology, combined with the current "Internet +" In the background of the times, technology has become an important force to promote financial development and has become a major trend. In the Internet era, mobile Internet, cloud computing, big data and other applications are no longer the core driving force for the development of fina...
