Multi-seal stamping system based on block chain smart contract

Abstract

The invention belongs to the technical field of information security, and particularly relates to a multi-seal stamping system based on a block chain smart contract. According to the invention, cooperation of multiple units and multiple seals is realized, a multi-seal examination and approval mode is creatively added on the platform side, the blank of such scenes in the market is covered, and a seal use examination and approval flow can be added by the units which are added into the platform; according to the invention, a set of localized or platform seal verification logic based on the smart contract is provided based on a specific hardware device, and manual verification on a webpage depending on a verification code is not needed, so that the verification workload is really reduced, and the device can be started only after local automatic verification.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a multi-seal affixing system based on a blockchain smart contract. Background technique [0002] The existing seal management platform based on blockchain technology cannot solve the automatic unlocking of the seal and the verification of the stamping results in the multi-party seal scenario. For a document that requires multiple parties to sign and verify (such as project acceptance documents, etc.), there are generally strict requirements. Stamping sequence, and the following units can be stamped after the previous units are stamped. In this scenario, in the existing solutions, only one application for stamping in the existing system is required for each stamping, and the latter node always has to query the authenticity of the stamping of the previous node before it can be stamped. [0003] Moreover, although in the existing technology, although the bl...

Problems solved by technology

[0003] Moreover, although in the existing technology, although the blockchain platform records the stamping result and generates verification information, subsequent users still need to log in to the platform to enter a lengthy verification code (the previous verification code must also be obtained). The relevant personnel of the stamping node send it to the inquirer) for inspection and verification. Although this enhances the credibility of the stamping behavior, it increases the user's verification and operation costs, especially when verification needs to be carried out across multiple companies. Companies need to log in to the platform and repeat the above steps several times to complete a compliant multi-party seal, which is cumbersome and has no practical value
