Blockchain-based method and system for encryption and storage of tender documents

Abstract

The embodiments of the present disclosure disclose a blockchain-based method and system for encrypting and storing bid documents. A specific implementation of the method includes: marking the bid documents to be stored to generate a marked bid document; in response to detecting a first selection operation acting on the encryption button corresponding to the above marked bid document, according to a preset user privacy key, perform signature processing on the above-mentioned marked bidding document to generate a signed bidding document; generate an encrypted file corresponding to the above-mentioned signed bidding document according to the public key corresponding to the above-mentioned marked bidding document; perform signature processing on the above-mentioned encrypted document according to the above-mentioned user private key , to generate an encrypted bidding file; compress the encrypted bidding file to generate a compressed package of the encrypted bidding file, and upload the compressed package of the encrypted bidding file to a preset server. This embodiment improves the confidentiality of the bidding documents and reduces the possibility of information leakage of the bidding documents.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of computers, and in particular, to a method and system for encrypting and storing bid documents based on blockchain. Background technique [0002] With the increasing number of suppliers, when selecting suppliers, suppliers are usually selected according to the bidding documents provided by each supplier. At present, when the bidding documents are sent to the supplier, the usual method is as follows: the bidding documents are directly transmitted to the server through the business personnel. [0003] However, there are usually the following technical problems with the above approach: [0004] First, the bidding documents are not signed, authenticated and encrypted, which may lead to information leakage of the bidding documents during the transmission process; [0005] Second, the account information of the business personnel who transmit the bidding documents is not authenticated, which may e...

AI Technical Summary

Problems solved by technology

[0004] First, the signature authentication and encryption processing of the bidding documents are not performed, which may lead to information leakage of the bidding documents during the transmission process;

[0005] Second, the account information of the business personnel who transmit the bidding documents is not authenticated, which may easily cause the leakage and tampering of the information of the bidding documents;

[0006] Third, it is impossible to perform file detection on the bidding documents uploaded to the server, and the bidding documents uploaded to the server are prone to damage or information leakage
