E-code Multi-imprints for Secure Electronic Document Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signature verification schemes are vulnerable to 'middleman attacks' where unauthorized parties can intercept and reroute transmissions, compromising the security of electronic document access and authenticity.
Innovation Solution
A platform generates unique patterns that are imprinted on documents, using multiple channels for verification and authentication, involving registered devices and executors with varying authority levels, to ensure secure execution and prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If email-based signature verification is used, then ease of operation is improved, but security is worsened due to vulnerability to middleman attacks
Solution Approach 1:
The verification code is segmented into multiple portions that are distributed across different communication channels. Each portion alone is insufficient for verification, but together they form the complete code. This segmentation prevents middleman attacks because the attacker cannot intercept all portions through a single channel.
Solution Approach 2:
The system introduces an intermediary verification platform that coordinates the distribution and combination of code portions across multiple channels. This intermediary ensures that no single channel contains the complete verification information, thereby preventing unauthorized interception while maintaining operational ease.
2Reliability
If multiple verification channels are used, then security is improved, but device complexity is worsened
Solution Approach 1:
The verification platform performs multiple functions through a single system: generating code portions, distributing them across different channels, verifying their combination, and managing executor credentials. This multi-functionality achieves enhanced security without proportionally increasing overall system complexity.
Solution Approach 2:
Registered devices automatically perform verification of code portions against their stored credentials without requiring manual intervention. The system self-manages the complex coordination of multiple channels through automated processes, reducing the operational complexity burden on users.
3Object-affected harmful factors
If identity verification is implemented, then fraud prevention is improved, but loss of time is worsened due to additional verification steps
Solution Approach 1:
Executors pre-register their devices and credentials with the verification platform before document execution. This preliminary setup stores verification information in advance, enabling rapid automated verification during actual document execution without requiring time-consuming manual identity confirmation at that moment.
Solution Approach 2:
The system provides immediate automated feedback on verification status by comparing the combined code portions against stored executor credentials. This real-time feedback mechanism quickly confirms or rejects verification attempts, preventing fraud while minimizing time loss through automated decision-making rather than manual review.

AI summary
Apparatus and methods for generating a unique token that can be imprinted on a document to attest to the verification of an executor's signature. The apparatus and methods may include a platform that may present a token electronically to the executor via a first electronic channel. The executor may use a registered device to capture a portion of the token, and transmit the portion from the registered device to the platform via a second channel to the platform. The platform may verify that the portion is registered to the executor. The platform may combine the portion with another portion of the token, and imprint the pair of combined portions on the document with another token.
