Smart Glass Eye Wear for Encrypted ATM Screen Decryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated transaction machines (ATMs) in public areas expose users' sensitive information, such as PINs and account details, making them vulnerable to fraud as they are displayed in unencrypted form, and there is no mechanism to provide a view of information in both unencrypted and encrypted states to the user and public respectively.
Innovation Solution
The use of smart-glass-based eye wear that generates a public/private key pair, allowing users to switch to an encrypted screen mode at the ATM through facial recognition and Bluetooth communication, ensuring only the user with the private key can decrypt the screen content, while others see an encrypted view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If ATM displays unencrypted information on screen, then user can view transaction information clearly, but sensitive information becomes vulnerable to theft by thieves at distance
Solution Approach 1:
The patent applies local quality by making the screen content visible in different encryption states to different observers. The smart glass device modifies the optical properties of the screen locally for the authorized user, allowing them to see unencrypted information while other observers see encrypted content. This resolves the contradiction by providing both clear visibility for the user and security against theft simultaneously.
Solution Approach 2:
The smart glass device acts as an intermediary between the ATM screen and the user's eyes. It intercepts the light from the screen and selectively decrypts the content for the authorized user wearing the glasses, while allowing encrypted content to pass through for other observers. This intermediary mechanism enables both clear information access for the user and security for the public.
2Ease of operation
If ATM provides unencrypted view to user, then user can read sensitive information, but public can also see unencrypted sensitive information leading to fraud
Solution Approach 1:
The patent implements local quality by creating different visual experiences for different observers of the same screen. The authorized user wearing smart glass sees unencrypted, readable information, while all other public observers see encrypted, unreadable content. This resolves the contradiction between readability for the user and protection from fraud for the public.
Solution Approach 2:
The patent segments the audience into two groups: authorized users with smart glass devices who see unencrypted content, and the general public who see encrypted content. This segmentation allows the ATM to provide readable information to legitimate users while preventing fraud from unauthorized observers, resolving the contradiction between ease of operation and harm prevention.
3Object-affected harmful factors
If ATM encrypts screen for public view, then sensitive information is protected, but user cannot view unencrypted transaction information
Solution Approach 1:
The smart glass device serves as an intermediary that selectively decrypts screen content for the authorized user. The ATM encrypts the screen for public protection, but the smart glass intercepts this encrypted signal and transforms it into readable form for the user wearing the glasses. This resolves the contradiction between information protection and user access.
Solution Approach 2:
The patent applies local quality by making decryption capability localized to the authorized user's viewing position through the smart glass device. The screen remains encrypted for the public, but locally decrypts for the user wearing the smart glass, thereby protecting information while maintaining user access.
4Reliability
If ATM displays encrypted information to all, then public cannot steal sensitive data, but user cannot perform transactions requiring unencrypted view
Solution Approach 1:
The patent resolves this contradiction by making the screen content locally unencrypted for the authorized user wearing smart glass, while remaining encrypted for all other public observers. This enables the user to perform transactions by viewing unencrypted information, while the public remains unable to steal sensitive data.
Solution Approach 2:
The smart glass acts as an intermediary device that enables transaction capability for the authorized user while maintaining security for the public. It decrypts the encrypted screen content locally for the user, allowing them to perform transactions, while the public continues to see only encrypted information that cannot be stolen.
Data Source
AI summary
Apparatus and methods for unlocking a communication terminal. The methods may include: at the communication terminal, receiving from eye wear of a user, a radio frequency (“RF”) signal that includes a public code. The methods may include: at the communication terminal, receiving from eye wear a request for text that is encrypted using the public code. The methods may include: responsive to the request, transmitting to the communication terminal encrypted text based on the public code. The methods may include displaying on the communication terminal the encrypted text. The methods may include detecting at the terminal, without displaying a decryption of the encrypted text, a user gesture based on the encrypted text. The methods may include providing to the user a private code corresponding to the public code. The private code may be configured to reside in machine readable memory on the eye wear.
