Solution Overview
Problem
Existing security and value documents with RFID functionality lack adequate protection mechanisms to prevent unauthorized data reading, allowing unauthorized access and potential misuse of biometric data.
Innovation Solution
Incorporating a cryptographic protocol for reader authentication and a display device that renders data locally without transmitting it, ensuring only authorized readers can initiate data reproduction, and using biometric and manipulandum-based mechanisms for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID interface is integrated into security documents for wireless data access, then data availability and convenience are improved, but unauthorized reading and data security are worsened
Solution Approach 1:
The patent introduces a display device as an intermediary between the RFID interface and the user. Instead of directly transmitting data via RFID, the system renders data visually on a display device (OLED, LCD, e-paper, etc.), which requires physical proximity and visual verification. This intermediary step prevents remote unauthorized reading while maintaining convenient data access for legitimate users.
Solution Approach 2:
The patent replaces the wireless electromagnetic field-based RFID data transmission with a visual display mechanism. By substituting the radio frequency communication channel with an optical display channel, the system eliminates the vulnerability to remote unauthorized access while preserving user access convenience through visual rendering of data on the document's display device.
2Adaptability or versatility
If data is transmitted via RFID interface for external systems to access, then system integration capability is improved, but data protection and user control are worsened
Solution Approach 1:
The display device serves as a controlled intermediary that allows external systems to verify data visually without enabling direct data extraction. External systems can authenticate the document's contents through the display, maintaining system integration capability while preventing unauthorized data copying or transmission through the RFID interface.
Solution Approach 2:
The patent segments the data access function into two distinct channels: RFID interface for authentication and verification only, and display device for data presentation. This segmentation allows external systems to integrate with the document for verification purposes while maintaining strict control over actual data access, as the RFID interface cannot transmit the displayed data without proper authentication.
3Reliability
If cryptographic protocol is implemented for reader authentication, then security is improved, but operational complexity and processing time are worsened
Solution Approach 1:
The cryptographic authentication protocol is executed in advance during the initial interaction between the RFID reader and the document, before any data is displayed or accessed. By performing authentication preliminarily, the system establishes security credentials upfront, allowing subsequent data display operations to proceed without repeated complex authentication steps, thus reducing overall operational complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents unauthorized data access and misuse by ensuring only authenticated readers can reproduce data, maintaining user control over their information and protecting against third-party and institutional misuse.
Implementation Method 1
The data can be rendered by a display device of the document so that it can be visually and cognitively grasped by a user
Implementation Method 2
The data stored on a contactless transponder, for example an RFID transponder, is made available via radio waves. At low frequencies, this happens inductively via a near field
