Solution Overview

Problem

Service providers and device manufacturers face challenges in securely transferring data via memory tags, such as RF memory tags, due to vulnerabilities in digital wallets and the need for effective mechanisms to manage accessibility states for secure data transfer.

Innovation Solution

A method and apparatus that determine the accessibility state of RF memory tags and grant access based on this state, using a connection between the tags, ensuring secure interaction and storage of sensitive information by differentiating between trusted and untrusted storage areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If access is granted for interaction between RF memory tags, then data transfer capability is improved, but security risk increases

Engineering Contradiction:
Improvedata transfer capabilityVSAvoidsecurity risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic access control by determining the accessibility state of the first RF memory tag before granting access. The system transitions between locked and unlocked states based on authentication results, allowing data transfer only when the tag is in an accessible state, thus dynamically balancing productivity and security

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces an intermediary accessibility state determination mechanism between the two RF memory tags. This intermediary layer authenticates the first tag's accessibility state and controls whether the connection between tags is permitted, acting as a security mediator that enables data transfer only under verified conditions

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If accessibility state determination is implemented, then security is improved, but system complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the storage system into trusted and untrusted storage areas within the device. This segmentation allows the accessibility state determination to focus only on controlling access to trusted storage, reducing the complexity burden while maintaining security for critical data

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary accessibility state determination and authentication before establishing the connection between RF memory tags. By determining the accessible state in advance and only then permitting data transfer, the system avoids the need for continuous complex verification during data transfer, reducing overall system complexity

Inventive Principle:
Principle #10Preliminary action

AI summary

An approach is presented for transferring data via radio frequency (RF) memory tags. The UE manager receives a request, at a device, to grant access for interaction between a first RF memory tag and a second RF memory tag, the first RF memory tag associated with one or more trusted storage. Further, the UE manager determines an accessibility state of the first RF memory tag, the one or more trusted storage, or a combination thereof. Then, the UE manager causes, at least in part, granting of the access based, at least in part, on the accessibility state. The access is via a connection between the first RF memory tag and the second RF memory tag.
