Head-Mounted Display Secure PIN Transmission via Optical Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transmitting PINs and confidential information, such as via separate letters or SMS, incur additional costs and risk interception by unauthorized parties, compromising security.
Innovation Solution
A method utilizing a head-mounted display device that supplies authentication information, reads it using a recording unit, and transmits identification information via an over-the-air interface to a service facility, ensuring secure display of confidential information only when both authentication and identification information match, thereby preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PIN is transmitted via separate letter, then security is improved compared to no transmission, but additional costs are incurred and risk of interception by unauthorized third party increases
Solution Approach 1:
The patent introduces a head-mounted display device as an intermediary between the user and the confidential information transmission system. The device captures authentication information from the user's environment (such as from a document or screen) and transmits it securely to the service facility, eliminating the need for separate PIN transmission while maintaining security.
Solution Approach 2:
The patent replaces the mechanical/mail-based PIN transmission system with an electronic/optical system. The head-mounted display uses a camera or optical sensor to capture authentication information and wireless communication to transmit it, substituting the physical letter delivery mechanism with electronic processes that reduce interception risks.
2Speed
If PIN is communicated via SMS, then transmission speed is improved, but costs are incurred and danger of nearby third party reading PIN increases
Solution Approach 1:
The patent applies local quality by making the authentication information capture and display process localized to the user's immediate visual field through the head-mounted display. The device captures authentication information from a specific local source (document, screen) and displays it only in the user's personal viewing zone, preventing nearby third parties from observing it while maintaining fast transmission.
Solution Approach 2:
The head-mounted display acts as an intermediary that captures authentication information locally and transmits it securely, replacing the SMS system. This intermediary device enables fast transmission while preventing shoulder-surfing attacks by processing and transmitting information without displaying it in a public or shareable format.
3Ease of operation
If confidential information is displayed on mobile radio device, then accessibility is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The patent moves the display function from a handheld device in the user's hand to a head-mounted display in the user's visual field. This dimensional change from hand-held to head-mounted positioning creates a more secure viewing experience where the information is naturally confined to the user's personal visual space, reducing unauthorized access while maintaining accessibility.
Data Source
AI summary
A method is provided for displaying confidential information, such as a cash-card secret code and/or a credit-card secret code. If the information transmitted to a service facility matches the information deposited there, the confidential information is displayed on a display device arranged on a user's head.
