Judgment method and system for electronic contract signing time accuracy

Abstract

The invention provides a judgment method and system for electronic contract signing time accuracy. According to the method, according to the characteristic that data in a block chain network cannot betampered, transfer operation is initiated in the block chain network, a real digital signature of an electronic contract is written into a transaction remark of the transfer operation, an obtained first digital signature is utilized to be compared with the real digital signature, signing time is compared with transaction time information of the transfer operation, and if the signing time and thetransaction time are different, it is determined that the signing time of the contract is tampered by someone, that is, the signing time is wrong. Through the judgment method and system, it is convenient to timely judge whether the signing time of the electronic contract is accurate, the signing time of the electronic contract is further determined as the transaction time, and a heavy loss is avoided for a signer of the electronic contract.

Description

technical field [0001] The present invention relates to the technical field of smart contracts, and more specifically, to a method and system for judging the accuracy of electronic contract signing time. Background technique [0002] With the continuous development of e-commerce, traditional paper contracts are being replaced by electronic contracts. Electronic contracts are usually concluded by means of electronic data exchange and electronic mail. This method is relatively cumbersome to operate. Since the electronic contract is not encrypted during its confirmation and transmission, the electronic contract is easily intercepted or modified illegally, posing a threat to the commercial secrets and transaction security of both parties to the contract, and to the security of the electronic contract. The signing process also lacks security controls. [0003] At present, some third-party electronic contract service companies adopt a centralized form and store electronic contra...

Problems solved by technology

[0004] In the prior art, it is only possible to judge whether the content of the electronic contract has been tampered with, but it is difficult to technically prove the validity of the signing time of the electronic contract

However, in some policy-related fields, such as real estate transactions, due to the different signing times of electronic contracts, it may have different impacts on the contract executors, and may even fail to perform the contract.
