Biometric Signature Pen With Time-Location Verification Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing paper-based handwritten signature verification systems are insecure and difficult to enhance without significant additional effort, as they cannot entirely prevent forgery and lack modern security features.
Innovation Solution
A signature system that integrates a writing instrument with identification devices, such as fingerprint or iris scanners, to collect user-specific data, generate an identification code, and display it on the document, combining this with chronological and location data to create a secure verification process, preventing post-factum falsification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional paper-based handwritten signature verification is used, then the system is simple and easy to operate, but the security is weak and susceptible to forgery
Solution Approach 1:
The patent merges a traditional writing instrument with multiple identification devices (fingerprint sensor, iris camera, microphone) and a code generation device into an integrated system. This combination allows the simple act of signing to simultaneously capture biometric data, generate identification codes, and create chronologically-located signatures, thereby enhancing security without requiring separate verification systems.
Solution Approach 2:
The writing instrument is designed to perform multiple functions: capturing handwriting signatures, collecting biometric identification data (fingerprint, iris, voice), generating identification codes, and recording chronological-location data. This multi-functionality allows a single device to provide comprehensive verification capabilities that replace multiple separate systems.
2Reliability
If additional identification devices are added to the writing instrument, then the security is enhanced, but the device complexity increases
Solution Approach 1:
The identification devices automatically capture biometric data (fingerprint, iris, voice) without requiring active user input beyond the natural signing action. The system performs identification and code generation automatically during the signing process, eliminating the need for users to manually enter additional verification information.
Solution Approach 2:
The identification devices and code generation functionality are pre-integrated into the writing instrument. When the user picks up the pen to sign, the identification process has already been prepared and will execute automatically, so no additional steps or preparations are needed from the user at the moment of signing.
3Loss of information
If only a handwritten signature is recorded on the document, then the process is simple, but the proof of identity and timing is insufficient
Solution Approach 1:
The system generates an identification code that is displayed on the writing instrument's display device and copied onto the document by the user. This code serves as a verifiable copy of the biometric identification data, providing proof of identity without requiring the actual biometric data to be physically present on the document.
Solution Approach 2:
The patent adds chronological data and location data as new dimensions to the signature verification process. These data elements provide temporal and spatial context to the signature, creating a multi-dimensional verification record that goes beyond the traditional two-dimensional handwritten signature on paper.

AI summary
A signature system for verifying a signature, includes a writing device which is equipped with identification devices for determining identification data which are linked to the identity of an user of the writing instrument, and code generating devices for generating an identification code from the identification data and from further data, the writing device further including display devices for displaying the identification code; as well as a corresponding signature method.
