Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

RFID tags pose security issues as any reader can activate and read the information stored on them, potentially allowing unauthorized access to sensitive data.

Innovation Solution

Implementing a secured RFID tag with a transmission control mechanism that selectively enables and disables data transmission, allowing only authorized access to sensitive information by enabling the tag only under specific conditions, such as location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If RFID tags store sensitive data for convenient access, then data accessibility is improved, but security is worsened because any reader can read the information

Engineering Contradiction:

Improvedata accessibilityVSAvoidunauthorized access

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent segments the RFID tag system into two distinct components: a regular RFID tag for storing non-sensitive data and a secured RFID tag for storing sensitive data. This segmentation allows different access control mechanisms to be applied to different data types, enabling convenient access to non-sensitive information while protecting sensitive information through the secured tag's transmission control mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The secured RFID tag acts as an intermediary between the data storage system and unauthorized readers. It mediates access to sensitive information by controlling transmission based on authorization status, allowing legitimate access while blocking unauthorized readers from obtaining sensitive data.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a secured RFID tag with transmission control is implemented, then security is improved, but device complexity is worsened

Engineering Contradiction:

Improveunauthorized access preventionVSAvoidsystem structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system is segmented into two separate RFID tags rather than creating one highly complex secured tag. This segmentation distributes the complexity across two simpler components, making the overall system more manageable while achieving the security goal through the coordinated operation of both tags.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent combines two RFID tags (regular and secured) into a single RFID device system. This merging allows the system to leverage the simplicity of regular RFID tags for non-sensitive data while incorporating security features only where needed, balancing complexity and security requirements.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

According to an example of the present subject matter, a secured radio frequency identification device includes: a first radio frequency identification (RFID) tag; and a secured radio frequency identification (RFID) tag having a transmission control for selectively enabling and disabling data transmission from the secured RFID tag. The first RFID tag is to store non-sensitive data from a data set and the secured RFID tag is to store sensitive data from the same data set such that all the data of the data set is only accessible when the secured RFID tag is enabled for data transmission.
