Embodiment 1

[0074] The data structure stored in the file in the embodiment of the present invention includes file header information (head), address information (address), file version information (vertion), account information (id), file generation time information (time), and data encryption technology identification information (DID); detailed as follows:

[0075] (1) Generation of private key and address:

[0076] (2) Encrypt the private key with a password to generate a key

[0077] (3) Write the corresponding string to the file:

[0078]

[0079] (4) Store the file on the local server.

[0080] (5) When a transaction request from a supply chain merchant is received, the file is parsed, the private key ciphertext and address are read from the file, and the ciphertext password is entered to decrypt the private key ciphertext before the transaction is performed.

[0081] The supply chain-based commercial data protection method and system provided by the present invention uses the generated priva...

Abstract

The invention relates to a commercial data protection method and system based on supply chain management. The method comprises the following steps: carrying out localized deployment on a responded service server; responding to the service data request to obtain request data; performing operation on data needing to be calculated of the service request to obtain operation data; encrypting the request data and the operation data to generate a private key ciphertext; and writing the private key ciphertext into a local server file or a database. According to the invention, the secure storage problem of the private key and the address of the user can be solved, the situation that the account information is stolen and threatened due to the fact that the private key and the address are stored in acentralized system is avoided, and the security of the user account information is better guaranteed.

Description

Technical field [0001] The present invention relates to the field of supply chain management, in particular to a method and system for protecting commercial data based on supply chain management. Background technique [0002] Supply chain management involves complicated permissions. The private key management and storage systems of each merchant in the supply chain are basically centralized. Private keys are easily stolen. Blockchain, as a kind of distributed ledger, is an Internet database. Technology is characterized by decentralization, openness and transparency. It was originally the underlying technology of Bitcoin and is currently widely used in finance and other fields. [0003] Inventory of the top ten data breaches in 2018: Facebook, A station, YTO, SF and other data were stolen. Facebook: 87 million user data leaks; ACFUN: 9 million user data leaks; Huazhu's multiple hotel chains: 240 million check-in records leaked; Marriott Starwood: 500 million customer user informat...
