Abstract

The embodiment of the invention provides an electronic bidding method and device based on a block chain and a storage medium. According to the embodiment of the invention, the sensitive information inthe bidding document is subjected to homomorphic encryption by adopting a homomorphic encryption method, and except the bidding sender, other participants can only compare and verify the bidding document under the encryption condition that the bidding document is in homomorphic encryption, but cannot obtain the specific amount of the bid. Therefore, leakage of sensitive service information is avoided, and benefits of bidders are guaranteed.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a block chain-based electronic bidding method, device and storage medium. Background technique [0002] In the electronic bidding system, there will be some sensitive information in the electronic bidding document, for example, the bidding amount. For the purpose of fair bidding, it is necessary to disclose the bidding amount after the bidding closes. However, the historical bid amount is easy to be used and analyzed to obtain bidding patterns, which leads to unfair competition. Contents of the invention [0003] Embodiments of the present invention provide a block chain-based electronic bidding method, equipment, and storage medium to avoid leakage of sensitive business information and protect the interests of bidders. [0004] In the first aspect, the embodiment of the present invention provides a blockchain-based electronic bidding meth...
