Augmented Reality Touchscreen Authentication via Encrypted Optical Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touchscreen devices are vulnerable to unauthorized access as users enter personal information, as attackers can observe or record PINs and passwords, and current protective features like angle-sensitive screens and physical shields are inadequate.
Innovation Solution
An augmented reality system that generates and presents encrypted optically readable codes on a touchscreen device, which can only be decoded and overlayed with images using a head-mounted augmented reality device, ensuring secure input by randomizing code placement and requiring user selection of images corresponding to the codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional password or PIN input methods are used on touchscreen devices, then user authentication is enabled, but the device becomes vulnerable to shoulder surfing and recording attacks
Solution Approach 1:
The patent transitions the authentication interface from a traditional 2D touchscreen to a 3D spatial arrangement of images in the physical world. Users authenticate by physically locating and touching images positioned at different spatial coordinates, adding a dimensional element that prevents observers from easily capturing or recording the authentication process while maintaining usability.
Solution Approach 2:
The patent introduces an intermediary layer between the user and the authentication system by using optically readable codes that display image locations. This intermediary mechanism allows the system to communicate authentication requirements without directly exposing sensitive information, as the codes only indicate positions rather than revealing the authentication sequence itself.
2Reliability
If optically readable codes are displayed on touchscreen to enable AR interaction, then secure authentication is achieved, but the interface complexity increases
Solution Approach 1:
The patent applies local quality by displaying optically readable codes only at specific locations where images are positioned, rather than covering the entire touchscreen. This localized approach maintains security functionality while minimizing visual clutter and interface complexity, allowing users to focus on relevant authentication elements without being overwhelmed by unnecessary information.
Solution Approach 2:
The authentication interface is segmented into discrete image positions, each marked by an optically readable code. This segmentation breaks down the complex authentication process into manageable individual elements, making the interface more comprehensible and easier to interact with while maintaining security through the distributed spatial arrangement of multiple code elements.

AI summary
As disclosed herein a method, executed by a computer, includes receiving, from an augmented reality device, a pairing request, negotiating with the augmented reality device to generate a new encryption key and a mapping plan for presenting optically readable codes, that correspond to one or more images, on a touch sensitive display device. The method further includes presenting, on the touch sensitive display device, the optically readable codes, and receiving a user selection from the touch sensitive display device. The optical codes are overlayed by the wearers of an augmented reality system with an un-encrypted or otherwise modified form of the optical code. A computer system, and a computer program product corresponding to the above method are also disclosed herein.
