Solution Overview

Problem

In communication environments based on one-to-one wireless standards, such as Bluetooth, it is challenging for IC chips to identify and exclusively control access from multiple applications on a smartphone, leading to potential data integrity and security issues due to the lack of distinct identification of transmission sources and destinations.

Innovation Solution

The implementation of a system where applications on a smartphone generate and share session IDs (session ID1 and session ID2) with IC chips, ensuring that each application can be uniquely identified and authorized, using these IDs to secure and manage data transmission and reception.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If one-to-one wireless communication standard is used, then communication simplicity is improved, but ability to identify and control multiple access sources deteriorates

Engineering Contradiction:
Improvecommunication simplicityVSAvoididentification accuracy of access sources
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent introduces session ID1 and session ID2 as intermediary identification elements that mediate between the one-to-one communication framework and multi-application access requirements. These session IDs act as intermediaries that carry application-specific identification information through the communication channel, enabling the IC chip to distinguish between multiple applications while maintaining compatibility with one-to-one communication protocols.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The identification process is segmented into two distinct session ID parameters (session ID1 and session ID2) that are transmitted separately. This segmentation allows the system to maintain the simplicity of one-to-one communication while embedding multiple layers of identification information that enable precise source identification and access control.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If session ID transmission is implemented, then access control precision is improved, but communication data volume increases

Engineering Contradiction:
Improveaccess control precisionVSAvoidcommunication data volume
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent changes the parameter structure by introducing session ID1 and session ID2 as additional communication parameters. These parameters enable precise access control by providing distinct identification values for each application session, allowing the IC chip to differentiate and control access from multiple applications while maintaining efficient data transmission.

Inventive Principle:
Principle #35Parameter changes

AI summary

[Object] To provide an information processing device, information processing method, and program that enable access from each of a plurality of access sources to be exclusively controlled even in a communication environment based on a standard in which one-to-one communication is assumed. [Solution] An information processing device includes: an acquisition unit configured to acquire identification information at least a part of which includes randomized information from an external device; and a control unit configured to set only communication data associated with the acquired identification information out of communication data transmitted from the external device as a processing target exclusively.
