Secure Pairing via Visual Code Verification for Wearables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pairing methods for intelligent wearable devices and terminals lack security, particularly in scenarios involving personal information and payments, as multiple devices may respond to connection requests, leading to potential security risks.
Innovation Solution
The method involves displaying an identification code by the wearable device, which is scanned and compared with a response from the terminal after a wireless broadcast, ensuring consistent codes for secure pairing, and optionally using pre-stored keys for encrypted communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth broadcast signal is used for pairing, then connection establishment is simple and fast, but security is compromised as multiple devices may respond
Solution Approach 1:
The patent applies preliminary action by having the wearable device display its identification code before the pairing process begins. The terminal scans this code in advance to obtain the correct identification, ensuring that the subsequent broadcast response verification is based on pre-confirmed identity information. This preliminary scanning and code obtaining step prevents security issues before they can occur during the actual pairing.
Solution Approach 2:
The patent implements feedback by requiring the wearable device to respond to the terminal's broadcast signal with its identification code, which the terminal then verifies against the previously scanned code. This feedback mechanism ensures that only the correct wearable device (the one whose code was scanned) can successfully pair, preventing unauthorized devices from establishing connections even if they receive the broadcast signal.
2Reliability
If identification code verification is added to ensure security, then pairing security is improved, but the pairing process becomes more complex
Solution Approach 1:
The patent replaces manual verification methods with automated code scanning and comparison. Instead of requiring users to manually check device identifiers or enter pairing codes, the system uses the terminal's camera or scanner to automatically capture the wearable's displayed identification code, and automatically verifies it against the broadcast response. This substitution of mechanical/manual verification with automated optical/electronic verification maintains security while reducing perceived complexity for the user.

AI summary
Implementations of the present application disclose a method, a system and an intelligent terminal for pairing between an intelligent wearable device and an intelligent terminal. The method includes: displaying, by the intelligent wearable device, an identification code; scanning, by the intelligent terminal, the identification code displayed by the intelligent wearable device; sending, by the intelligent terminal, a wireless broadcast signal, and monitoring a response sent to the intelligent terminal; returning, by the intelligent wearable device, the response after the intelligent wearable device receives the wireless broadcast signal sent by the intelligent terminal, where the response includes the identification code; receiving, by the intelligent terminal, the response, and extracting the identification code from the received response; and comparing, by the intelligent terminal, the extracted identification code and the scanned identification code, and pairing up with the intelligent wearable device if the extracted identification code and the scanned identification code are consistent. By using the implementations of the present application, the intelligent terminal and the intelligent wearable device can be securely paired.
