Portable Device Attitude Detection for Secure Settlement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional online shopping systems lack effective measures to prevent unauthorized access and ensure secure settlement processing using IC cards, particularly in portable information processing devices, which can lead to unauthorized transactions.
Innovation Solution
Incorporating a portable information processing device with non-contact communication capabilities, attitude detection, and restriction mechanisms, such as attitude sensing and standby time management, to prevent unauthorized access by ensuring the device is in a specific attitude and limiting communication distance and time with the IC card.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If non-contact communication with IC card is enabled for convenient settlement processing, then ease of operation is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The patent changes the parameter of device attitude from irrelevant to critical by introducing attitude detection. The settlement processing is enabled only when the device attitude matches a predetermined condition (e.g., held horizontally by the user), transforming the system from always-accessible to conditionally-accessible, thereby enhancing security while maintaining convenience for legitimate users.
Solution Approach 2:
The attitude detection unit acts as an intermediary between the user operation and the settlement processing system. It introduces an additional verification layer that mediates whether the non-contact communication with the IC card should be permitted, preventing unauthorized access while allowing convenient operation for legitimate users who hold the device correctly.
2Ease of operation
If standby processing waits for IC card proximity for extended period, then ease of operation is improved, but vulnerability to unauthorized access increases
Solution Approach 1:
The system performs preliminary attitude verification before entering the IC card reading standby state. By checking whether the device attitude satisfies the predetermined condition beforehand, the system prepares a secure environment for subsequent IC card communication, preventing unauthorized access during the extended standby period while maintaining user convenience.
Solution Approach 2:
The attitude detection mechanism provides preliminary anti-action against unauthorized access by establishing a protective condition before the IC card reading function becomes active. This preemptive measure counteracts potential harmful factors during standby by ensuring only properly authenticated users can initiate the IC card communication process.
3Productivity
If settlement processing is performed without attitude verification, then productivity is improved, but security deteriorates
Solution Approach 1:
The attitude verification is performed as a preliminary action before the main settlement processing begins. This initial check ensures that security conditions are met before any sensitive operations occur, allowing the subsequent settlement processing to proceed quickly without repeated verification, thus maintaining productivity while enhancing security.
Solution Approach 2:
The settlement processing is segmented into distinct phases: attitude verification phase and execution phase. The attitude check is separated as a preliminary gatekeeping step, while the actual settlement operations proceed efficiently once authorized. This segmentation allows security verification without compromising the speed of the core transaction processing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances security by restricting settlement processing unless the device is in a valid attitude and within a controlled communication distance and time, thereby reducing the risk of unauthorized transactions.

AI summary
A device of an example is a portable information processing device performing settlement processing concerning purchase of a merchandise article or a right in cooperation with a given server, comprising: a non-contact communication unit performing non-contact communication with a data storage medium; a data acquisition unit acquiring data stored in the data storage medium, through the non-contact communication unit as a part of the settlement processing; a settlement processing unit performing settlement based on the data acquired by the data acquisition unit, in cooperation with the server, as a part of the settlement processing; a detection unit detecting at least one of attitude, movement, and a placement state of the own device; and a restriction unit acquiring a detection result from the detection unit and then, when the detection result does not satisfy a given condition, restricting performing of at least a part of the settlement processing.
