Angle-Selective ATM Display Using Imaging Analysis for Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
ATMs in public places expose users to security risks as bystanders can view sensitive information, leading to potential theft, identity fraud, and physical threats.
Innovation Solution
Implementing a system that uses imaging sensors and machine learning to determine a user's viewing angle and display account information only at that angle, while obscuring it from bystanders, using false or truncated information when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If account information is displayed on an ATM screen in public places, then users can access their banking information, but bystanders can also view the sensitive information leading to security risks
Solution Approach 1:
The display screen presents different visual information to different viewers based on their location. Users viewing from authorized positions see actual account information, while bystanders from other positions see obscured or false information. This spatial differentiation of display content resolves the contradiction by allowing information access for legitimate users while preventing unauthorized viewing by bystanders.
Solution Approach 2:
The system introduces an intermediary layer between the account information and the display screen - a machine learning model that analyzes viewer characteristics and determines what information to present. This intermediary processes viewer data and dynamically controls display content, enabling selective information disclosure that protects users while maintaining access for authorized individuals.
2Reliability
If the display shows different information to different viewers, then security is improved, but the device complexity increases due to imaging sensors and machine learning processing
Solution Approach 1:
The display screen serves multiple functions simultaneously - it acts as both a standard information display device and a security control mechanism. The same screen displays different content to different viewers without requiring separate physical displays, thereby improving security while minimizing the increase in device complexity through multi-functional use of existing components.
Solution Approach 2:
The system uses the ATM's existing display infrastructure to provide security functionality. Rather than adding completely separate security devices, the system repurposes the display screen itself to convey different information to different viewers, allowing the display system to serve both information delivery and security protection functions.
3Reliability
If the display limits information visibility to specific viewing angles, then unauthorized access is prevented, but the user experience may be affected if users cannot view information comfortably
Solution Approach 1:
The display content dynamically adjusts based on the viewer's position and characteristics. As users move to different positions, the system continuously analyzes their location and appropriately updates the displayed information to maintain both security and usability. This dynamic adaptation ensures users can view information comfortably from various positions while unauthorized viewers continue to see obscured content.
Data Source
AI summary
Systems and methods disclosed may include receiving verification information from a user via a graphical user interface (GUI) and capturing visual information of the user via at least one imaging sensor. A viewing angle of the user may be continuously determined and based on the captured visual information. Upon determining that the verification information is valid, the method may include causing a display to output the account information and other information where the account information is displayed at the continuously determined viewing angle of the user, and the other information may be displayed at one or more viewing angles other than the continuously determined viewing angle of the user.
