Electronic Whiteboard User Authentication and Email Authorship
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic whiteboards lack effective user authentication and data management, leading to inconveniences such as unauthorized access and unclear authorship of visual information, especially when data is reused across sessions or shared via email.
Innovation Solution
An electronic whiteboard system that includes an authentication unit, identification information obtainment, visual information storage, read, display, and email transmission units, allowing user authentication, data association with user IDs, and replacing the electronic whiteboard's email address with the user's address for clear authorship in emails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication is implemented on electronic whiteboards, then user identification and data management are improved, but system complexity and ease of operation deteriorate
Solution Approach 1:
The patent introduces an account server as an intermediary component that handles authentication and user management functions externally. The electronic whiteboard itself remains simple, while the account server manages user registration, authentication, and data association. This mediator approach allows user identification accuracy to improve without significantly increasing the complexity of the whiteboard device.
2Loss of information
If visual information is stored with user identification, then data management and authorship identification are improved, but ease of operation and convenience deteriorate
Solution Approach 1:
The system automatically associates visual information with user identification without requiring manual input from users. When users authenticate, the system automatically links their created or accessed content to their user ID, eliminating the need for users to manually remember or input identification numbers. This self-service approach preserves authorship information while maintaining ease of operation.
3Loss of information
If the electronic whiteboard's mail address is replaced with user's mail address for email transmission, then authorship identification is improved, but system complexity increases
Solution Approach 1:
The account server acts as a mediator that handles the email transmission logic. When visual information is transmitted via email, the system uses the user's authenticated identity to determine the transmission source, rather than using a fixed whiteboard email address. This allows clear authorship identification while keeping the whiteboard itself simple, as the complex email routing logic resides in the external account server.
Data Source
AI summary
An electronic whiteboard to display visual information including handwritten data superimposed with a display image, includes a unit to authenticate a user; a unit to obtain user identification information for identifying the user in case where authentication of the user has succeeded; a unit to store the visual information associated with the user identification information; a unit to read the visual information associated with the user identification information; a unit to display the visual information; a unit to set a mail address of the electronic whiteboard as a transmission source, and to transmit the visual information to a specified destination by an e-mail; a unit to store the mail address of the user associated with the user identification information; and a unit to replace the transmission source by using the specified mail address of the user if the authentication of the user has succeeded.
