Remote Control Authorization via Stored Code Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote-controlled devices lack a secure and flexible method for authorizing remote controls to operate them, leading to potential unauthorized access and limited compatibility with different devices.
Innovation Solution
A method and system that utilize a stored set of unique RC codes to authenticate and authorize remote controls, allowing for addition, deletion, and management of authorized codes, ensuring secure operation and compatibility with multiple devices through a processor and memory-based solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote-controlled device accepts instructions from any remote control, then compatibility and ease of operation are improved, but security and authorization control deteriorate
Solution Approach 1:
The system performs preliminary authorization by storing a set of authorized RC codes in memory before operation. When a remote control sends an instruction, the processor checks whether the RC code is in the stored authorized set before executing the command. This preliminary verification ensures security is maintained while preserving ease of operation for authorized users.
2Reliability
If a remote-controlled device restricts operation to authorized remote controls only, then security is improved, but compatibility and ease of operation deteriorate
Solution Approach 1:
The system achieves universality by allowing multiple different remote controls with different RC codes to operate the same remote-controlled device. The processor is designed to recognize and accept instructions from any remote control whose code is in the authorized set, making the system compatible with various remote controls while maintaining security through the authorization check.
3Adaptability or versatility
If a remote-controlled device supports multiple remote controls, then adaptability and versatility are improved, but device complexity deteriorates
Solution Approach 1:
The system segments the authorization management by separating the RC code verification function from the main control logic. The processor checks the RC code against the stored authorized set as a distinct step before executing commands. This segmentation allows multiple remote controls to be supported without significantly increasing overall system complexity, as the authorization mechanism is a modular addition to the control system.

AI summary
A method and system for remotely controlling a remote-controlled device (RCD) includes receiving an instruction from a remote control (RC). The instruction may include an RC code and a control code. The RC code may identify the RC and the control code may identify an operation to be performed on the RCD. RC codes matching an authorized set of RC codes may cause the control code to be accepted, since the RC is authorized. If a non-matching RC code is received, the control code may be rejected as coming from a prohibited RC. An authorization mode on the RCD may allow modification of the authorized set of RC codes.
