Electronic Signature Verification Using Camera-Based Identity and Matrix Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic signature methods fail to provide conclusive proof of consent from multiple signatories, especially in scenarios where physical presence is required, and are complicated due to the lack of smart card readers in everyday devices and cumbersome processes for authorization.
Innovation Solution
The method employs a 'selfie' technique using front cameras to capture group photographs with a cryptographic fingerprint, leveraging facial recognition for identity validation and notarization, ensuring simultaneous consent and presence, with timestamped and geolocated photos stored on a notarization server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electronic signature methods using asymmetric cryptography are used, then security and authentication are improved, but device complexity and ease of operation deteriorate due to lack of smart card readers and cumbersome authorization procedures
Solution Approach 1:
The patent replaces the mechanical smart card reader system with an optical camera-based identification system. Instead of requiring physical smart cards and dedicated readers, the system uses a camera to capture images of identification documents and performs optical character recognition and facial recognition to authenticate signatories, thereby simplifying device requirements while maintaining security
Solution Approach 2:
The patent creates digital copies of identification documents and facial features through camera imaging. These copies are then processed through OCR and facial recognition algorithms to extract identifying information, replacing the need for physical document verification and smart card insertion while preserving authentication reliability
2Reliability
If physical signing ceremonies are conducted to ensure simultaneous consent, then conclusive proof of consent is improved, but loss of time and productivity deteriorate due to the need for in-person meetings
Solution Approach 1:
The patent performs preliminary actions by capturing identification documents and facial images before the actual signing process. The system pre-validated signatory identities through OCR and facial recognition, and pre-generates cryptographic signatures, allowing the actual consent process to be completed electronically without requiring physical presence while maintaining proof of simultaneous consent
Solution Approach 2:
The patent introduces a digital intermediary system that mediates between physical presence requirements and electronic signing. This system uses camera-captured images, cryptographic fingerprints, and timestamped records as intermediaries to verify identity and consent simultaneously, eliminating the need for physical gatherings while providing conclusive proof equivalent to in-person ceremonies
3Measurement precision
If group selfies with cryptographic fingerprints are used to verify simultaneous consent, then measurement precision of consent verification is improved, but device complexity increases due to coordination requirements among multiple signatories
Solution Approach 1:
The patent merges multiple verification functions into a single coordinated process. Instead of requiring separate verification steps for each signatory, the system combines facial recognition, OCR document verification, cryptographic fingerprint generation, and timestamping into an integrated group signing process that automatically coordinates all signatories through their mobile devices, thereby improving measurement precision while managing complexity through unification

AI summary
The invention concerns a method for electronic signing of a document by a plurality of signatories, comprising a step of acquiring a photograph of at least one of said signatories and identifying said signatory using the photograph, and a step of associating the document in a digital form with the identified signatory, characterized in that it comprises: - a prior step of calculating a matrix code by a cryptographic processing TC applied to the document, - said step of acquiring a photograph consisting of acquiring a photograph of at least one signatory bearing a physical medium representing the matrix code, - a step of validating: o the identity of the signatory on the photograph and, o the conformity of the matrix code calculated by the cryptographic processing TC applied to the document held by a signatory, with the matrix code on the photograph.
