Direct Communication Security via Pre-Authentication and Adaptive Power Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Direct communication between terminals without a network environment poses security risks due to the lack of effective user verification mechanisms, especially when transmitting user data.
Innovation Solution
Implementing a method where terminals establish a direct communication connection by acquiring and verifying user verification information, such as fingerprints, before initiating data transmission, using secure transmission modes like Wi-Fi hotspot, Bluetooth, or NFC, and adjusting communication modes based on power thresholds to optimize energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct communication is established between terminals without network environment, then data transmission can be achieved, but security is compromised due to lack of user verification mechanisms
Solution Approach 1:
The patent applies preliminary action by performing user verification through fingerprint acquisition and authentication before establishing the direct communication connection. The verification process is executed in advance during the connection establishment phase, ensuring that only authenticated users can initiate data transmission, thereby resolving the security vulnerability without requiring complex ongoing verification mechanisms
Solution Approach 2:
The patent introduces an intermediary verification mechanism where the terminal device acts as a mediator between the users. The system incorporates a verification module that mediates the authentication process by comparing fingerprint information against stored user data, providing a security layer that does not require external network infrastructure while maintaining reliable security verification
2Use of energy by moving object
If power consumption is optimized by switching communication modes, then energy efficiency improves, but communication reliability may be affected
Solution Approach 1:
The patent applies dynamics by implementing a dynamic communication mode selection mechanism that adapts to real-time power conditions. The system monitors power availability and automatically switches between different communication modes (e.g., Wi-Fi hotspot, Bluetooth, NFC) based on current power levels, ensuring optimal energy efficiency while maintaining communication reliability through adaptive mode selection rather than static configuration
Solution Approach 2:
The patent utilizes parameter changes by modifying communication parameters such as transmission power, data rate, and communication protocol based on available power thresholds. When power is sufficient, higher-rate modes are used; when power is limited, lower-consumption modes are activated, thereby optimizing energy usage while preserving communication reliability through parameter adaptation

AI summary
The present disclosure provides a communication method and device. The method includes that: when an instruction for instructing transmitting user data via a direct communication connection is received, user verification information is acquired, the user verification information including verification data input through a first terminal; the user verification information is sent to a second terminal; when verification success information is received from the second terminal, a first direct communication connection is established with the second terminal; and the user data is sent to the second terminal via the first direct communication connection.
