Touchless Identity Card Emulator for Secure RFID Retrofitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID-based access control systems face security vulnerabilities and require costly infrastructure upgrades, as physical ID cards are prone to copying and replacement, and existing card readers are often bulky and hardwired, necessitating labor-intensive rewiring and new badge issuance.
Innovation Solution
A touchless identity card emulator device that wirelessly communicates with existing RFID readers, using a smartphone app to authenticate users and emulate a physical badge, allowing secure access control without physical keys and enabling retrofitting of existing systems to extend their lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical ID cards are used for access control, then user authentication is established, but security vulnerabilities arise due to copying and sniffing methods
Solution Approach 1:
The patent uses virtual copies of physical badges stored in the emulator device. Instead of using actual physical cards that can be copied, the system creates and stores virtual representations of badge credentials in secure memory, which are then transmitted wirelessly to authenticate users without exposing the original physical card data to sniffing or copying attacks
Solution Approach 2:
The patent replaces the mechanical/physical card system with an electronic/wireless system. The physical badge is substituted by an emulator device that communicates wirelessly with RFID readers, eliminating the need for physical card insertion or contact, thereby removing the vulnerability to physical copying and sniffing methods
2Reliability
If existing card readers are replaced with new infrastructure, then functionality and security are improved, but cost and installation time increase significantly
Solution Approach 1:
The patent introduces an intermediary emulator device that acts as a bridge between existing RFID readers and the authentication system. This intermediary component allows the legacy readers to continue functioning while adding security features through the emulator, eliminating the need to replace the entire reader infrastructure
Solution Approach 2:
The emulator device is designed to be universally compatible with multiple types of existing RFID readers and various card formats. This multi-functionality allows a single emulator solution to work across different reader types and authentication protocols, providing security upgrades without requiring reader-specific customization or replacement
3Ease of operation
If physical badges are distributed to users, then access control is enabled, but loss and misplacement increase
Solution Approach 1:
The patent replaces physical badges with virtual badge copies stored in the emulator device. Users authenticate through the emulator using wireless communication, eliminating the need for physical cards that can be lost or misplaced. The virtual credentials remain secure in the emulator's memory and can be accessed without physical media
Solution Approach 2:
The patent extracts the authentication functionality from the physical badge itself and relocates it to the emulator device. The credential data is separated from any physical card and stored securely in the emulator, allowing access control to function without requiring users to carry or handle physical badges
