Author Identity Verification via Simultaneous Biometric and Writing Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to reliably verify the identity of individuals who create written or digital content, such as documents, artworks, or musical works, as they lack a secure and efficient means to link the author's identifying features with their generated material.
Innovation Solution
A system comprising a computer database and processor that stores and compares images of identifying features with captured images during the content creation process, using cameras to simultaneously record the author's biometric identifiers and their actions, ensuring identity verification through equivalence matching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional identity verification methods are used, then the process is simple and quick, but the reliability of identity verification is insufficient
Solution Approach 1:
The system performs preliminary registration of individuals' biometric data and writing characteristics before the actual verification process. During registration, the system captures and stores reference images of identifying features (fingerprint, facial image, or iris pattern) along with reference writing samples. This preliminary action creates a database of authentic characteristics that enables reliable verification during subsequent document creation events without requiring complex real-time analysis
Solution Approach 2:
The system creates optical copies of biometric identifiers and writing characteristics. Cameras capture images of the individual's identifying features and writing actions, storing these visual copies in a database. During verification, the system compares the captured copies with stored reference copies to confirm identity, eliminating the need for direct physical contact or complex sensing while maintaining high reliability
2Measurement precision
If multiple identifying features are captured and compared, then the verification accuracy increases, but the time required for verification increases
Solution Approach 1:
The system allows for partial verification by enabling the use of a single identifying feature (fingerprint, facial image, or iris pattern) rather than requiring all three. The camera captures whichever feature is most convenient or clearly visible at the moment of document creation. This partial action approach maintains sufficient verification accuracy while significantly reducing the time required compared to capturing and processing multiple features
Solution Approach 2:
The system pre-registers multiple identifying features and writing characteristics during an initial setup phase. This preliminary action stores reference data for all possible biometric modalities, enabling the verification process to quickly compare against pre-stored references without requiring real-time capture of multiple features. The system can selectively use the most readily available feature during verification, balancing accuracy and speed
3Reliability
If simultaneous capture of writing action and biometric identifier is implemented, then the link between author and content is strengthened, but the device complexity increases
Solution Approach 1:
The system merges the capture of biometric identifiers and writing actions into a single integrated process. A camera positioned to view the writing surface simultaneously captures both the individual's identifying feature and their writing characteristics in the same field of view. This merging creates an inseparable link between the author's identity and the content being created, as both are recorded together in a single image or video sequence
Solution Approach 2:
The camera system serves multiple functions: it captures the biometric identifier, records the writing action, and documents the temporal sequence of events. This single device performs what would otherwise require separate sensors and recording systems, reducing overall system complexity while maintaining the reliability of author-content linkage through multi-functional operation

AI summary
A method and apparatus for identifying the writer of a document, where identifying information for each of a plurality of registered human individuals is stored in a database, calls for capturing local images of an individual making writings and/or keyboard entries and determining whether the individual making these writings and/or keyboard entries is the same as one of the registered individuals whose identifying information is stored in the database. The identifying information stored in the database includes both an alphanumeric identifier and an image of a unique, visually observable biologic identifier on a body portion of each registered individual. The local images include both:(i) the making of the writings and/or keyboard entries by the individual whose identifying information may be stored in the database; and(ii) a body portion of this same individual on which is visible the biologic identifier.
