Communication Apparatus Secure Remote Control via Encrypted Short Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available communication apparatuses are vulnerable to data privacy infringement and loss due to manual configuration and management, which can lead to unauthorized shutdown of GPS, making them difficult to locate and increasing data security risks.
Innovation Solution
A communication apparatus with a short message receiving and managing unit that processes messages with a predetermined format, including an unencrypted prefix and encrypted fields containing a device serial number and operation command, to securely control operations such as starting GPS or locking the screen, ensuring only authorized users can execute commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If communication apparatuses are made portable and compact, then ease of operation is improved, but security and reliability deteriorate due to high chance of getting lost or stolen
Solution Approach 1:
The communication apparatus automatically receives and executes short messages containing operation commands without requiring manual user interaction. The device self-manages operations such as starting/stopping GPS, adjusting volume, or locking screens by processing encrypted short messages, enabling remote control while maintaining security through automated authentication and command validation.
2Ease of operation
If communication apparatuses are configured and managed by hand, then ease of operation is improved, but security deteriorates due to infringement of personal privacy and leakage of important data
Solution Approach 1:
The patent replaces manual mechanical configuration with automated electronic control through short message processing. Operation commands are transmitted via encrypted short messages and executed automatically by the communication apparatus, eliminating the need for physical interaction with the device and reducing security risks associated with manual handling.
3Ease of operation
If global positioning systems are shut down by a third party, then ease of operation is affected, but security is compromised as the position cannot be located
Solution Approach 1:
The system implements feedback mechanisms where the communication apparatus sends status information back to the remote controller. When GPS status changes or location information is obtained, the device automatically reports back, allowing the remote user to monitor and control GPS functionality while ensuring location tracking capability is maintained through automated status verification.
Data Source
AI summary
A communication apparatus and its setting method are provided. The communication apparatus has a processor and a memory device storing a short message receiving module configured to, when executed by the processor, determine whether the short message received by the communication apparatus conforms with a predetermined format. The short message includes an unencrypted prefix and multiple encrypted fields including a device serial number of the communication apparatus, a time at which the short message is sent and an operation command that controls the communication apparatus to execute a corresponding operation. The short message received by the communication apparatus is decoded to obtain the operation command when the short message conforms with the predetermined format. The operation command controls the communication apparatus to execute the corresponding operation, and the predetermined format includes at least an unencrypted field and at least an encrypted field.
