Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for network-connected devices, such as printers, face challenges in balancing security and operability, particularly in ensuring secure remote access while simplifying user interactions.
Innovation Solution
A communication apparatus equipped with dual wireless communication units and a control unit that transmits remote control information and screen state updates, using one unit for secure pairing and another for operational control, allowing secure remote access without requiring frequent password inputs by using short-range wireless communication for authentication and BLE for data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password-based authentication is used for remote control, then security is improved, but operability deteriorates due to frequent password inputs required
Solution Approach 1:
The patent divides the wireless communication function into two separate units: a first wireless communication unit for transmitting remote control information and a second wireless communication unit for receiving authentication information. This segmentation allows different communication protocols to be used for different purposes, enabling secure authentication while maintaining ease of operation for remote control tasks.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism where authentication information is transmitted via the second wireless communication unit and stored in storage units. This intermediary layer allows the system to verify user identity without requiring repeated password inputs during remote control operations, thus improving operability while maintaining security.
2Reliability
If dual wireless communication units are used for authentication and control, then security is improved, but device complexity increases
Solution Approach 1:
The patent designs the communication apparatus with multi-functional components that serve multiple purposes. The control unit manages both wireless communication units and coordinates their operations, while storage units store both authentication information and remote control information. This multi-functionality reduces the need for entirely separate authentication and control systems, thereby limiting the increase in device complexity.
3Reliability
If authentication information is stored in storage units, then security is improved, but loss of time occurs during authentication processes
Solution Approach 1:
The patent implements preliminary authentication by storing authentication information in advance in storage units. Once authentication is performed via the second wireless communication unit, the authenticated state is stored and can be used for subsequent remote control operations without requiring repeated authentication. This preliminary action reduces authentication time for subsequent operations while maintaining security through the stored authentication credentials.
Data Source
AI summary
A communication apparatus transmits, to another apparatus via a first wireless communication, remote control information which is related to remote control of the communication apparatus, and transmits, when information which is received from the other apparatus via the second wireless communication corresponds to the remote control information, information related to a screen of a remote control permitted state to the other apparatus via second wireless communication. When the information which is received from the other apparatus via the second wireless communication does not correspond to the remote control information, information related to a login screen for the remote control is transmitted.
