Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If facial recognition and machine learning are implemented to identify users and track access in real-time, then document security and user identification accuracy are improved, but device complexity and processing requirements increase
Solution Approach 1:
The system performs preliminary actions by capturing and processing facial images before document access is granted. The facial recognition database is pre-populated with user facial data, and the machine learning model is trained in advance to recognize patterns. This allows real-time identification without compromising security while managing complexity through pre-computation.
Solution Approach 2:
The system creates a digital copy of the user's facial features by generating a computerized image and comparing it against stored facial recognition data. This copying approach enables accurate identification without requiring physical presence verification, reducing system complexity while maintaining high reliability for security purposes.
2Measurement precision
If access tracking is implemented at the character level with facial recognition, then measurement precision of user interactions is improved, but loss of time for processing and data management increases
Solution Approach 1:
The system maintains continuous facial recognition processing throughout the document interaction session. Instead of periodic checks, the machine learning model continuously analyzes facial images to track user identity and associated character-level interactions in real-time. This continuous action eliminates gaps in tracking precision while optimizing processing time through sustained analysis rather than repeated full scans.
Solution Approach 2:
The system replaces traditional mechanical or manual tracking methods with automated machine learning-based facial recognition. This substitution enables precise character-level tracking of user interactions without manual intervention, achieving high measurement precision while reducing time loss through automated processing of facial features and document interaction data.
3Reliability
If real-time facial feature processing is used to monitor document access, then security control over document sections is improved, but use of energy and computational resources increases
Solution Approach 1:
The system applies partial action by focusing facial recognition processing only on relevant facial features necessary for identification rather than analyzing all image data. The machine learning model processes only the essential facial characteristics needed for security verification, achieving effective security control while reducing computational energy consumption by avoiding excessive processing of unnecessary data.
4Measurement precision
If facial recognition database comparison is performed for each user access attempt, then user identification accuracy is improved, but productivity and speed of access are reduced
Solution Approach 1:
The system performs preliminary actions by pre-processing and storing facial recognition data in an optimized database structure before access attempts occur. Facial features are extracted and organized in advance, allowing rapid comparison during actual access attempts. This preliminary preparation maintains high identification accuracy while significantly improving access speed and productivity.
Solution Approach 2:
The system creates simplified copies of facial recognition data that can be quickly compared against new facial images. Instead of performing complex full-face analysis for each access attempt, the system uses pre-generated facial feature copies that enable rapid matching while maintaining accurate user identification. This copying mechanism balances identification precision with access productivity.
Data Source
AI summary
A method of providing, by a computing device, access to a user of sections of an electronic document. The method includes receiving, by a computing device, a computerized image of a user accessing an electronic document. The computing device further accesses a facial recognition database and compares the computerized image to one or more entries in the facial recognition database to determine an identity of the user. The user is provided access to one or more sections of the electronic document based upon the identity of the user.
