Wireless Display Privacy via Encrypted Representative Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies fail to protect user privacy in display apparatuses like electric note-messengers, as they allow irrelevant individuals to read displayed content, compromising user confidentiality.
Innovation Solution
An electric system comprising a first wireless apparatus that encrypts information and transmits it to a display apparatus, which displays representative information instead of the encrypted data, while a second wireless apparatus decrypts the information for authorized access, ensuring privacy by not directly displaying the intended information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display apparatus directly displays the transmitted information, then the information is easily accessible to users, but user privacy is compromised and irrelevant personnel can read the content
Solution Approach 1:
The patent introduces an intermediary representation mechanism where the original information is transformed into representative information that displays meaningful characteristics but cannot be directly read or copied. This intermediary form protects privacy while maintaining usability, as it conveys essential information without exposing sensitive data.
Solution Approach 2:
The patent creates a copy of the information in a protected form (representative information) that resembles the original in certain aspects (displaying meaningful content) but differs in critical ways (cannot be directly read or extracted). This allows the display function to be maintained while preventing unauthorized access to the actual information.
2Object-affected harmful factors
If encrypted information is transmitted and stored, then user privacy is protected, but the information cannot be directly displayed or read by unauthorized personnel
Solution Approach 1:
The patent creates a protected copy (representative information) that preserves the essential display function while eliminating the security vulnerability of displaying raw encrypted data. The representative information maintains visual meaningfulness for legitimate users while preventing direct reading or copying by unauthorized parties.
Solution Approach 2:
The patent applies different quality characteristics to different aspects of the information display: the representative information has high visual meaningfulness for legitimate users but low readability for unauthorized parties. This local differentiation of information quality allows simultaneous achievement of privacy protection and useful display functionality.

AI summary
An electric system including a first wireless apparatus, a display apparatus and a second wireless apparatus is provided. A first information is encrypted to be a first encrypted information and sent wirelessly by the first wireless apparatus. The display apparatus includes a display unit and a wireless communication unit electrically connected to the display unit. The wireless communication unit receives the first encrypted information and cause the display unit to display a first representative information corresponding to the first encrypted information. The first representative information and the first encrypted information are different. The second wireless apparatus reads the first encrypted information by the wireless communication unit, and the first encrypted information is decrypted to be the first encrypted information by the second wireless apparatus.
