Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RFID enabled mobile devices are vulnerable to identity theft and theft itself due to lax security and lack of authentication measures, as they can emulate RFID cards or readers, and existing RFID systems have limited security features.
Innovation Solution
An RFID enabled mobile device equipped with sensors like cameras, accelerometers, and GPS, which use sensor attributes and contextual data to control the release of RFID information and authentication data to an RFID interrogation system, minimizing identity theft by making secure security decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID enabled mobile device emulates RFID card or reader functionality, then convenience is improved by eliminating need for separate RFID card, but security deteriorates due to vulnerability to skimming and theft
Solution Approach 1:
The system performs preliminary authentication actions before releasing RFID information. The controller checks sensor attributes (accelerometer data, camera verification, GPS location) in advance to determine whether to allow RFID communication, preventing unauthorized access before it can occur
Solution Approach 2:
The patent introduces sensor attributes as an intermediary layer between the RFID transceiver and the external RFID interrogation system. These sensor attributes (motion data, location, camera verification) act as mediators that control and filter when RFID information is released, adding a security gateway
2Reliability
If RFID enabled mobile device uses sensor attributes to control RFID information release, then security is improved by minimizing identity theft, but device complexity increases due to multiple sensors and processing requirements
Solution Approach 1:
The patent leverages existing multi-functional mobile device components (accelerometer, camera, GPS, processor) already present in modern smartphones for their primary purposes, repurposing them for security verification. This avoids adding dedicated security hardware while achieving enhanced security functionality
Solution Approach 2:
The mobile device uses its own built-in sensors and processing capabilities to perform self-verification and security control. The device autonomously evaluates its sensor attributes and makes security decisions without requiring external security hardware or complex additional components

AI summary
An RFID enabled mobile device is configured to provide a secure release of RFID information. The RFID enabled mobile device, such as an RFID enabled cellular telephone, includes a set of sensors, such as a camera, one or more accelerometers, a wireless transceiver configured to send and receive data with an Internet device, and a global positioning system (GPS) receiver. The RFID enabled mobile device utilizes sensor attributes or information from one or more sensor of the set of sensors and, based upon the sensor attributes, controls the release of RFID information and/or other authentication data to an RFID interrogation system. In essence, the RFID enabled mobile device leverages from the conventional sensors typically incorporated as part of the mobile device and uses contextual data from its sensors and communication partners to make security decisions regarding the release of RFID information.
