1Object-affected harmful factors
If existing physical privacy filters are used on device screens, then some level of privacy is maintained, but they do not protect against direct viewing and do not work with printed items
Solution Approach 1:
The patent replaces physical privacy filters with an augmented reality-based decryption system. Instead of using mechanical/optical privacy filters that block viewing angles, the system uses software-based encryption and AR display to dynamically control information visibility. The encrypted code is displayed on any medium (screen or print), and the AR device decrypts and overlays sensitive information only when the device is actively capturing the code, eliminating the need for physical filters and providing universal compatibility.
Solution Approach 2:
The patent introduces an augmented reality device as an intermediary between the encrypted code and the user. The AR device acts as a mediator that captures the encrypted code, processes it through decryption algorithms, and presents the decrypted information in an augmented reality overlay. This intermediary layer provides privacy protection by ensuring that only the AR device user can view the decrypted information, while others see only the encrypted code regardless of the display medium.
2Ease of operation
If sensitive information is displayed on a user device in public areas, then users can access the information, but others in close proximity can also view it
Solution Approach 1:
The patent transitions the display from a two-dimensional screen or paper to a three-dimensional augmented reality space. The decrypted sensitive information is overlaid in AR proximate to the encrypted code, creating a spatial layer that is only visible through the AR device. This dimensional change allows users to access information easily through their AR device while preventing bystanders from viewing it, as the AR overlay does not project to physical space in a visible manner.
Solution Approach 2:
The patent implements dynamic control of information visibility based on the active capture state of the AR device. The system continuously monitors whether the AR device is capturing the encrypted code and dynamically adjusts the decryption and display state accordingly. When capture is detected, the AR device receives the decrypted code for display; when capture is not detected, only the encrypted code is visible. This dynamic behavior ensures accessibility for authorized users while maintaining security against unauthorized viewing in public areas.
3Ease of operation
If the decrypted code is provided continuously, then users can access information conveniently, but unauthorized users can also access it without active viewing
Solution Approach 1:
The patent implements periodic verification of the AR device's capture state to control decryption. Instead of providing continuous decryption, the system periodically checks whether the AR device is actively capturing the encrypted code and adjusts the decryption state accordingly. This periodic action maintains security by ensuring decryption is only active when needed, while preserving convenience for authorized users who have the proper AR device.
Solution Approach 2:
The patent employs feedback mechanisms where the system monitors the capture state of the AR device and uses this information to control the decryption process. The system receives feedback from the AR device about whether it is capturing the encrypted code, and this feedback directly influences whether the decrypted code is provided. This closed-loop feedback system ensures that decryption is tightly coupled with active viewing, maintaining both security and convenience.
