Biometric Lockset Deceptive Feedback for Unauthorized Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic deadbolts lack effective mechanisms for managing user access and visibility, particularly in distinguishing between authorized and unauthorized users, and providing feedback to users without compromising security or awareness.
Innovation Solution
A biometric wireless electronic lockset with a processor, memory, user interface, wireless communication, and biometric sensors that compares received biometric data to stored data to determine user authorization, and provides modified feedback to unauthorized users while maintaining security and administrative control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the electronic deadbolt provides clear feedback to unauthorized users, then user awareness of access status is improved, but security is compromised as unauthorized users may identify themselves
Solution Approach 1:
The patent converts the potentially harmful situation of unauthorized access attempts into a beneficial security feature by using deceptive feedback. When an unauthorized user attempts access, the system provides false feedback indicating successful authentication, thereby preventing the unauthorized user from knowing they have been identified while still maintaining accurate security control through the hidden authorization status
2Measurement precision
If the electronic deadbolt distinguishes between authorized and unauthorized users, then access control precision is improved, but user interface complexity increases due to multiple feedback types
Solution Approach 1:
The patent applies different feedback qualities to different user types while maintaining a unified interface. Authorized users receive accurate feedback reflecting their true authorization status, while unauthorized users receive deceptive feedback that appears successful. This local differentiation of feedback quality allows precise user identification without requiring complex interface variations
3Reliability
If the electronic deadbolt maintains accurate authorization status for all users, then security control is improved, but ease of operation deteriorates as unauthorized users receive confusing feedback
Solution Approach 1:
The patent introduces deceptive feedback as an intermediary layer between the true authorization status and the user experience. This intermediary provides unauthorized users with simplified, confusion-free interaction by presenting false successful authentication feedback, while the system maintains accurate authorization tracking in the background for security purposes
Data Source
AI summary
A biometric wireless electronic lockset includes a processor, a battery, a memory communicatively connected to the processor, a user interface, a wireless communication interface, a locking bolt, a motor, and a biometric sensor. The processor is configured to execute instructions which cause the processor to compare stored biometric data to a received first biometric data. Each known user entry includes a user identity of a known user, biometric data, and an indication of whether the known user is an authorized user. Based on a determination that the first biometric data corresponds to a known user entry and whether or not the known user is an authorized user or an unauthorized user, a plurality of responses may be generated.
