Display Apparatus IC Card Authentication Meeting Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies require users to manually search for and authenticate to access previously displayed meeting data, which is inefficient and time-consuming, especially when resuming meetings.
Innovation Solution
A display apparatus and method that utilizes an IC card to store and retrieve meeting identification information, allowing users to automatically access and display associated presentation data without the need for re-authentication, by using short-range communication to link the IC card with the display apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually search for and authenticate to access previously displayed meeting data, then data security is maintained, but access time and operational efficiency deteriorate
Solution Approach 1:
The system performs preliminary authentication by storing authentication information and meeting identification data in the IC card during the initial login. This preliminary action eliminates the need for re-authentication when accessing previous meeting data, reducing access time while maintaining security through the pre-validated credentials stored in the card.
Solution Approach 2:
The IC card serves as an intermediary device that stores both authentication information and meeting identification data. This intermediary enables the system to verify user identity and retrieve meeting data without requiring real-time server authentication, thus maintaining security protocols while significantly reducing access time.
2Measurement precision
If users manually search for previously displayed meeting data, then data accuracy is ensured, but operational complexity and time consumption increase
Solution Approach 1:
The system enables self-service by automatically matching the meeting identification data stored in the IC card with the stored presentation data. This automatic matching eliminates the need for users to manually search through multiple meetings, reducing operational complexity while ensuring data accuracy through precise identification matching.
Solution Approach 2:
The system provides feedback by displaying the meeting identification information and associated presentation data directly to the user after successful card authentication. This feedback mechanism confirms data accuracy by showing the user the specific meeting data retrieved, eliminating the need for manual verification while maintaining precision.
3Speed
If authentication information is stored locally in the display apparatus, then access speed improves, but system security and data protection deteriorate
Solution Approach 1:
The IC card acts as a secure intermediary that stores authentication information externally in a tamper-resistant device. This approach maintains system security by keeping credentials outside the display apparatus while enabling fast access through local verification of the card's stored data, thus achieving both speed and security.
Solution Approach 2:
The system segments the authentication and data storage functions by separating authentication information (stored in IC card) from presentation data (stored in display apparatus). This segmentation allows fast local access to presentation data while maintaining security through the distributed architecture, where critical credentials remain in the secure card device.
Data Source
AI summary
A display apparatus capable of displaying previously-displayed presented data stored in association with meeting identification information identifying each meeting, includes circuitry configured to receive particular meeting identification information stored at an information processing apparatus from the information processing apparatus; and display at least a part of particular presented data associated with the received particular meeting identification information, on a display.
