Cloud-Based Data Transmission for Conference Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conference support systems face increased data transmission and load issues as the number of users attending a conference grows, as they require file servers and complex access rights management, leading to inefficient data distribution among portable terminals.
Innovation Solution
A data processing device and method that utilizes cloud services to store and transmit data, allowing users to select accessible cloud services based on user accounts, thereby reducing data transmission loads by enabling multiple users to access data stored in a single cloud service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is downloaded among portable terminals of users attending a conference, then data can be accessed by multiple users, but the number of data transmissions and receptions increases and the load to each portable terminal increases
Solution Approach 1:
The patent introduces a file server as an intermediary device that stores conference data centrally. Instead of direct peer-to-peer data transmission between portable terminals, all data access requests are routed through the file server, which manages data storage and distribution efficiently, reducing the transmission load on individual terminals.
Solution Approach 2:
The patent consolidates data storage and management functions into a single file server, merging multiple data sources into one centralized location. This allows all conference attendees to access the same consolidated data set rather than requiring each terminal to maintain and share copies of the data.
2Reliability
If a file server is provided and access rights are set up, then data can be securely accessed by conference attendees, but the system complexity and setup requirements increase
Solution Approach 1:
The patent implements an automatic authentication mechanism where the portable terminal's authentication information (such as certificate information) is automatically used to access the file server. The system self-manages the authentication process without requiring manual configuration of access rights for each user, reducing setup complexity while maintaining security.
Solution Approach 2:
The patent uses a universal authentication approach where the portable terminal's existing authentication credentials serve multiple purposes - both for identifying the user and for accessing the file server. This multi-functional use of authentication information simplifies the access rights management system.
3Adaptability or versatility
If data is transmitted to all portable terminals in a conference, then all users can access the data, but the data transmission load increases with the number of users
Solution Approach 1:
The file server acts as an intermediary that handles data storage and retrieval, eliminating the need for repeated data transmission to each portable terminal. The terminal only needs to establish a connection with the file server and request data as needed, significantly reducing the energy consumption associated with data transmission.
Solution Approach 2:
The data is pre-loaded into the portable terminal's authentication information or made readily available through the file server before the conference begins. This preliminary preparation eliminates the need for extensive real-time data transmission during the conference, reducing energy consumption.

AI summary
A data processing device is provided with a job accepting portion to accept a job to transmit data to a transmission destination defined in relation to a transmission-destination user, a candidate deciding portion to decide on one or more cloud services in which an operating user who inputted the job has an account to be a candidate service, a service deciding portion to decide on a candidate service which is accessible by the transmission-destination user among one or more candidate services decided, to be an accessible service, and a data transmission portion to store the data in the decided accessible service as well as to transmit access information for accessing the data stored in the accessible service to the transmission destination for the transmission-destination user.
