Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current online shopping systems face challenges in securely and efficiently processing settlements using data storage mediums like IC cards, particularly in preventing fraudulent data acquisition and ensuring secure communication distances for non-contact transactions.
Innovation Solution
A settlement system that includes a data storage medium with a storage unit and non-contact communication capabilities, a server device for settlement processing, and information processing devices with non-contact communication units. The system implements a restriction unit to control communication distances, uses a wireless communication unit for longer-range communication, and includes a standby time control mechanism to manage data acquisition from the data storage medium, ensuring secure and efficient settlement processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If non-contact communication is used for data acquisition from IC cards in online shopping systems, then transaction convenience and speed are improved, but vulnerability to fraudulent data acquisition and security breaches increases
Solution Approach 1:
The patent applies local quality by differentiating standby time settings between portable information processing devices and stationary information processing devices. Portable devices, which are more vulnerable to theft and fraudulent use, are assigned shorter standby times (first standby time) compared to stationary devices (second standby time). This localized security measure strengthens protection where it is most needed while maintaining system-wide efficiency.
Solution Approach 2:
The patent changes the parameter of standby time based on device type and usage context. By dynamically adjusting the standby time parameter - shorter for portable devices and longer for stationary devices - the system optimizes the balance between transaction speed and security. This parameter change allows the system to respond differently to security risks based on the specific device characteristics.
2Reliability
If shorter standby time is set for portable information processing devices to prevent fraudulent acquisition, then security is improved, but transaction efficiency may be reduced
Solution Approach 1:
The patent applies local quality by implementing differentiated standby time policies for different device types. Portable information processing devices receive shorter standby times (first standby time) to prevent fraudulent acquisition, while stationary devices receive longer standby times (second standby time) to maintain transaction efficiency. This localized approach ensures security measures are applied where most needed without unnecessarily impacting overall system productivity.
3Ease of operation
If communication distance is not restricted in non-contact communication, then ease of operation is improved, but risk of unauthorized data acquisition increases
Solution Approach 1:
The patent applies preliminary action by establishing communication distance restrictions before actual data acquisition occurs. The restriction unit pre-configures maximum communication distances for non-contact communication, ensuring that even if a device is within range, unauthorized data acquisition cannot occur beyond the restricted distance. This preliminary protective measure maintains user convenience within acceptable ranges while preventing unauthorized access.
