Blockchain Digital Mark Generation for Tamper-Proof Certificates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital certificates are susceptible to tampering and unauthorized alteration, lacking security and legal efficacy due to their ease of copying and falsification, despite providing convenience over paper-based certificates.
Innovation Solution
A blockchain-based system for generating digital marks, where entity information is stored on a blockchain, generating a digital mark based on transaction identification, and associating it with the entity information to ensure endorsement and prevent unauthorized use, using a digital seal or signature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital certificates are implemented as digital images or PDF renderings to provide convenience over paper certificates, then ease of operation is improved, but reliability deteriorates because they are susceptible to tampering and unauthorized alteration
Solution Approach 1:
The patent introduces blockchain technology as an intermediary layer between the digital certificate and the实体 it represents. The blockchain stores immutable records of certificate issuance and entity information, serving as a trusted mediator that verifies authenticity without requiring physical paper certificates. This resolves the contradiction by maintaining digital convenience while adding a layer of tamper-proof verification through the blockchain's cryptographic security and distributed consensus mechanism.
2Reliability
If paper certificates are used with rubber-ink seals or signatures to provide legal effect, then reliability is improved, but ease of operation deteriorates because they can be easily lost or damaged and require physical handling
Solution Approach 1:
The patent replaces the mechanical system of paper certificates with rubber-ink seals and physical signatures with a digital system using blockchain-based digital marks. The blockchain stores cryptographic proofs and transaction identifications that serve as immutable digital equivalents of physical seals and signatures. This substitution maintains legal effectiveness through cryptographic verification while eliminating the physical handling, loss, and damage issues associated with paper certificates.
3Ease of operation
If digital certificates are made easier to copy than paper certificates to improve ease of operation, then ease of operation is improved, but reliability deteriorates because they become easier to falsify
Solution Approach 1:
The patent applies the copying principle in a controlled manner by allowing digital certificates to be easily copied and distributed, but incorporates blockchain-based digital marks that contain unique cryptographic identifiers and transaction hashes. These digital marks act as immutable fingerprints that can be verified against the blockchain record, ensuring that while the certificate can be copied for distribution, any falsification can be detected by verifying the cryptographic integrity against the original blockchain-stored information.

AI summary
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating digital marks. One of the methods includes: obtaining entity information of an entity; transmitting the entity information to one or more nodes of a blockchain for storage in the blockchain; obtaining a transaction identification associated with storing the entity information in the blockchain; and generating a digital mark for the entity based at least on the transaction identification.
