Solution Overview

Problem

Existing online payment systems using intelligent terminals are vulnerable to payment viruses, which can read SMS verification codes, embed malicious code into payment applications, and steal user bank account and password information, compromising payment security.

Innovation Solution

A wearable electronic device with a processor, memory, communications unit, input unit, and data processing unit is used to switch between a first and second operating system. The device receives transaction data from an intelligent terminal, determines its correctness, and performs encryption or signature processing using the second operating system before sending the processed data back to the intelligent terminal for online payment completion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If online payment is performed using a conventional intelligent terminal with a single operating system, then the operation is convenient and simple, but the payment security is compromised due to vulnerabilities to payment viruses and malicious code

Engineering Contradiction:
Improvepayment securityVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the operating system into two distinct parts: a first operating system for general operations and a second operating system specifically for payment processing. This segmentation isolates payment functions in a dedicated secure environment, preventing payment viruses from the general system from compromising payment security. The processor switches between these two operating systems based on operational needs, maintaining both convenience and security.

Inventive Principle:
Principle #1Segmentation

2Reliability

If payment processing is performed in a secure environment with operating system switching, then payment security is improved, but the operation complexity increases

Engineering Contradiction:
Improvepayment securityVSAvoidoperation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically manages the complexity of operating system switching through intelligent detection mechanisms. When payment-related applications or transactions are detected, the processor automatically switches to the second secure operating system without requiring user awareness of the underlying complexity. After payment completion, it automatically returns to the first operating system, making the secure process transparent to the user.

Inventive Principle:
Principle #25Self-service

3Reliability

If data encryption and verification are performed for each transaction, then data security is enhanced, but the processing time increases

Engineering Contradiction:
Improvedata securityVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The second operating system is pre-configured with secure encryption algorithms and verification mechanisms before payment transactions occur. Security credentials, encryption keys, and verification protocols are prepared in advance within the secure environment. When a payment transaction is initiated, the system simply executes pre-prepared secure operations rather than setting up security infrastructure during the transaction, reducing processing time while maintaining security.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention relates to a wearable electronic device, and a data processing method and system. The wearable electronic device includes: a processor, a memory, a communications unit, an input unit, and a data processing unit. The memory is configured to store software programs and modules of a first operating system and a second operating system. The processor switches the first operating system to the second operating system according to a first operation instruction that is entered by a user and received by the input unit. The communications unit receives, by using a first application supported by the second operating system, first information that includes transaction data for completing online payment and that is sent by an intelligent terminal. The processor is further configured to determine, according to a second operation instruction received by the input unit, that the first information is correct. The data processing unit performs, by using the second operating system, encryption or signature processing on the first information that is determined to be correct by the processor, to obtain second information. The communications unit sends, to the intelligent terminal by using the first application, the second information obtained by the data processing unit.
