Secure Element Applet Management via Dynamic Trigger Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for managing applets in secure elements lack flexibility, as they only allow for uniform settings such as registration periods and position information, making it difficult to delete or re-add applets based on daily user behaviors.
Innovation Solution
An information processing device and method that includes a trigger acquisition unit and a management unit, which acquires triggers and manages applets in a secure element based on these triggers, allowing for dynamic deletion or re-addition of applets in response to user behaviors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uniform settings (Single Triggers) such as registration period and position information are used for deleting applets, then the system is simple to operate, but the system cannot adapt flexibly to daily user behaviors
Solution Approach 1:
The patent applies the Dynamics principle by transitioning from static, uniform deletion triggers to dynamic, multi-type triggers that adapt to user behavior. The system now supports multiple trigger types including time-based triggers, position-based triggers, and usage count-based triggers, allowing the applet management system to dynamically respond to changing user needs rather than relying on fixed deletion conditions
Solution Approach 2:
The patent implements Parameter changes by introducing multiple dimensions for trigger settings beyond the traditional single uniform condition. The system now allows configuration of diverse parameters including deletion time, deletion count, position information, and usage frequency, enabling flexible adaptation to different user scenarios while maintaining systematic control through structured parameter management
2Adaptability or versatility
If the number of applets in the secure element increases, then more secure application programs can be executed, but the storage region becomes insufficient
Solution Approach 1:
The patent applies the Discarding and recovering principle by implementing automated mechanisms to delete unnecessary applets and recover storage space. The system uses multiple trigger types (time-based deletion, position-based deletion, usage count-based deletion) to automatically identify and remove applets that are no longer needed, thereby freeing up storage capacity for new secure application programs without requiring manual user intervention
Solution Approach 2:
The system implements Self-service by enabling automatic applet management through configured triggers. The secure element autonomously monitors conditions such as time, position, and usage frequency, and automatically deletes applets when predetermined conditions are met, eliminating the need for users to manually manage limited storage space while maximizing the number of available secure applications

AI summary
The present disclosure relates to an information processing device, an information processing method, a program, and an information processing system each capable of achieving flexible use of a storage region of a secure element. When a trigger is acquired by an external trigger device from the outside, an applet is installed or deleted into and from the secure element according to the type of the acquired trigger. The information processing device and the like of the present disclosure are applicable to an electronic apparatus including a secure element.
