Iris Recognition Portable Device Proximity Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing iris recognition portable devices cannot prevent unauthorized individuals from viewing personal information displayed on the device, even when security measures are in place to prevent direct access.
Innovation Solution
Incorporating a proximity sensor and iris recognition camera that sense the proximity and iris of nearby users, determining whether they are registered users and selectively activating a security mode to change the display or lock the screen if they are not.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If iris recognition method is used to prevent unauthorized access, then direct access security is improved, but ability to prevent sneaking a look at personal information deteriorates
Solution Approach 1:
The system performs preliminary iris recognition detection when a second user approaches the device before personal information is displayed or accessed. By detecting the presence of a non-registered user in advance and preemptively changing the display content or locking the screen, the system prevents potential information leakage before it can occur, rather than merely blocking access attempts.
Solution Approach 2:
The iris recognition camera and proximity sensor act as intermediary detection mechanisms between the unauthorized user and the personal information on the display. This intermediary system detects approaching users and triggers security responses (display change or screen lock) that mediate between potential threats and protected information, preventing direct viewing of sensitive data.
2Loss of information
If security mode is activated to prevent information leakage, then personal information protection is improved, but user convenience deteriorates
Solution Approach 1:
The security system dynamically adjusts its response based on real-time detection conditions. When a non-registered user is detected, the system selectively activates security modes (changing display or locking screen) only when necessary, rather than maintaining constant security measures. This dynamic approach ensures information protection while minimizing unnecessary disruptions to legitimate user operations.
Solution Approach 2:
The security response is applied locally and selectively rather than globally. The system changes display content or locks the screen only when specific conditions are met (detection of non-registered user in proximity), leaving normal operations unaffected when no threat is present. This localized security application maintains convenience for authorized users while providing protection when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents the leakage of personal information by identifying and responding to non-registered users, ensuring that only authorized individuals can view sensitive information.
Implementation Method 1
A proximity of a second user is sensed while a first user who is a registered user views a display screen of the device
Implementation Method 2
The iris recognition camera generates first iris information by acquiring an image of an iris of the second user
Data Source
AI summary
A proximity of a second user is sensed while a first user who is a registered user views an iris recognition portable device. Whether the second user is registered is checked according to whether an iris of the second user is recognized. The displayed screen may be altered when the second user is determined to be a non-registered user.
