Digital Notarization via Biometric Identity Attestation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital signature verification methods are cumbersome, time-consuming, and lack high fidelity, as they rely on manual verification or signature experts, and electronic signature services do not adequately authenticate identities.
Innovation Solution
A system for digital notarization using a biometric identification service, where a signature requesting service receives a payload identifying a digital item and a person, and an identity service uses digital representations of biometrics to determine identity and generate an encrypted data structure with identity attestations, allowing for secure and efficient validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification or signature expert analysis is used to verify signature validity, then verification can be performed, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces manual mechanical verification processes with automated biometric identification systems. The biometric service automatically compares signature characteristics against stored biometric data to verify identity, eliminating the need for cumbersome manual inspection by experts while maintaining high reliability.
Solution Approach 2:
The system enables self-verification through automated biometric matching. The verification process serves itself by automatically comparing signature data against stored biometric templates without requiring external expert intervention, thereby reducing both time and operational complexity.
2Reliability
If signature verification is performed by asking the person to verify their signature, then verification can be achieved, but it is not much different than having the person sign all over again
Solution Approach 1:
The patent replaces the mechanical act of re-signing with automated biometric verification. The system captures biometric data (such as fingerprint, facial recognition, or handwriting characteristics) and automatically compares it against stored templates to verify identity, eliminating the need for the person to physically sign again while maintaining authentic verification.
Solution Approach 2:
The system uses stored biometric copies (templates) of the person's identifying characteristics to verify their identity. Instead of requiring the person to create a new signature, the system compares the current biometric input against the stored copy, providing convenient yet reliable verification.
3Measurement precision
If extensive research is conducted by signature experts to achieve significant fidelity level, then verification accuracy improves, but the process becomes even more cumbersome and time-consuming
Solution Approach 1:
The patent replaces complex manual expert analysis with automated biometric identification systems. The biometric service uses sophisticated algorithms to compare signature characteristics against stored templates, achieving high fidelity verification automatically without requiring expert researchers to conduct extensive manual analysis.
Solution Approach 2:
The biometric service acts as an intermediary between the signature verification need and the biometric data storage system. It automatically performs the complex comparison and analysis tasks that would otherwise require expert researchers, providing high-fidelity verification while simplifying the overall process.
Data Source
AI summary
A system performs digital notarization using a biometric identification service. A signature requesting service receives a request to validate a digital item with a signature for a person. The signature requesting service provides a payload that identifies the digital item and/or the person to an identity service. The identity service obtains one or more digital representations of biometrics for the person, determines an identity for the person, and returns a data structure including the payload and one or more identity attestations regarding the determined identity. The identity service encrypts at least a portion of the data structure using a private encryption key. A public encryption key for the identity service can then be used to decrypt the portion to verify that the data structure was generated by the identity service after determining the identity. In this way, validation can be verified to the full trust level of the identification service.
