Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information processing systems fail to notify relevant applications of transactions performed between a device and an external device in real-time, leading to inefficiencies and potential security risks due to lack of immediate data access and validation.
Innovation Solution
An information processing apparatus and method that includes a sensing unit to detect transactions, an acquisition unit to gather data, a determination unit to identify notification targets based on service IDs, a verification unit to validate applications, and a notification unit to inform relevant, validated applications of transaction data, ensuring secure and timely information dissemination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an SP application needs to grasp transaction information, it must actively access the secure element and middleware, then <improved or preserved characteristic> the application can obtain transaction data, but <worsened characteristic> the system complexity and access contention increase
Solution Approach 1:
Instead of having applications actively access the secure element to obtain transaction information, the patent inverts the approach by having the secure element or middleware automatically notify applications of transaction occurrences. This inversion eliminates the need for complex access procedures and reduces system complexity while ensuring applications receive transaction information.
Solution Approach 2:
The secure element performs self-service by automatically detecting transactions and notifying relevant applications without requiring external requests. This self-service mechanism reduces the burden on applications and simplifies the overall system architecture while maintaining information accessibility.
2Speed
If applications frequently access the secure element to check transaction data, then <improving_feature> the information freshness is improved, but <worsening_feature> the access contention and processing overhead increase
Solution Approach 1:
The patent implements continuous monitoring of transactions by the secure element or middleware, which continuously detects transaction occurrences and immediately notifies applications. This continuous action ensures information freshness without requiring applications to repeatedly access the secure element, thereby maintaining processing efficiency.
Solution Approach 2:
The system implements a feedback mechanism where the secure element or middleware detects transactions and automatically provides feedback to relevant applications through notifications. This feedback loop ensures applications receive up-to-date transaction information without frequent active access, reducing processing overhead and contention.
3Loss of information
If all applications are notified of every transaction, then <improving_feature> the information dissemination is improved, but <worsening_feature> the notification overhead and resource consumption increase
Solution Approach 1:
The patent applies local quality by notifying only specific applications that are relevant to particular transaction types rather than all applications uniformly. The middleware or secure element determines which applications should receive notifications based on transaction characteristics, reducing unnecessary notification overhead and resource consumption while ensuring relevant information reaches the appropriate applications.
Solution Approach 2:
The notification system is segmented to target specific applications based on their relevance to transaction types. Instead of a blanket notification approach, the system divides notification delivery into targeted segments, reducing overall notification overhead while maintaining effective information dissemination to relevant applications.
4Speed
If applications access transaction data without verification, then <improving_feature> the access speed is improved, but <worsening_feature> the security risks increase
Solution Approach 1:
The patent implements preliminary verification of application validity by the middleware or secure element before allowing access to transaction data or sending notifications. This preliminary action ensures that only authorized applications can access transaction information, maintaining security without significantly impacting access speed for verified applications.
Data Source
AI summary
There is provided an information processing apparatus having a secure element mounted therein. The information processing apparatus in which a device that performs a transaction with an external device is mounted includes: a sensing unit that senses that a transaction has occurred between the device and the external device; an acquisition unit that acquires data from the device, in response to the sensing unit sensing the occurrence of the transaction; a determination unit that analyzes the data acquired by the acquisition unit, and determines applications as notification targets; a verification unit that verifies validity of the applications as the notification targets; and a notification unit that notifies a relevant application whose validity has been confirmed among the notification targets, of the data acquired by the acquisition unit.
