RFID Transceiver Authorization for Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for protecting products against piracy are inadequate in terms of data protection and consumer privacy, as RFID tags can be read unnoticed, allowing for unauthorized data access and creation of consumer movement profiles.
Innovation Solution
A method and system where the authenticity of a product is checked only after prior authorization of a reader, using a transceiver unit with a stored reference value, ensuring that data cannot be queried without owner consent, involving encrypted communication and authentication processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID tags are used for product authentication, then product authenticity can be verified, but data protection and consumer privacy are compromised due to unnoticed data reading
Solution Approach 1:
The patent applies preliminary action by requiring prior authorization from the product owner before any data can be read from the RFID tag. The owner must explicitly grant permission through the reading device, and only then can authentication data be accessed. This prevents unnoticed data reading while maintaining authentication capability.
Solution Approach 2:
The patent introduces an intermediary mechanism where the RFID tag stores encrypted authentication data and the reading device acts as a mediator that can only access this data with proper authorization. The authorization process serves as a control layer between the RFID tag and any external reading device, preventing unauthorized access.
2Reliability
If RFID tags store serial numbers for authentication, then product verification is enabled, but consumer movement profiles can be created without consent
Solution Approach 1:
The system requires preliminary authorization before any data can be read from the RFID tag. Without this prior consent, the tag remains inaccessible to reading devices, preventing creation of movement profiles or other consumer data collection activities.
Solution Approach 2:
The RFID tag implements self-protection by automatically rejecting unauthorized reading attempts. The tag actively prevents data extraction without external authorization, giving the consumer control over their own data and preventing privacy violations.
3Object-affected harmful factors
If authorization mechanism is added to RFID system, then data protection is improved, but system complexity increases
Solution Approach 1:
The RFID tag performs self-protection by automatically verifying authorization before allowing any data access. The tag independently manages its own security, rejecting unauthorized reading attempts without requiring complex external authentication systems or additional hardware components.
Solution Approach 2:
The patent extracts the authorization verification function directly into the RFID tag itself, separating the security mechanism from the reading device. This allows the tag to independently handle authorization and data protection, simplifying the overall system architecture while maintaining strong security.

AI summary
The invention relates to a method for verifying the authenticity of a product (100), comprising the following steps: - an identifier that is associated with the product is detected; - the identifier is entered into a reading device (106) encompassing an interface (110) for communicating, via radio, with a transceiver unit (104) which is assigned to the product and in which a reference value (114) for the identifier is stored; - the reading device is granted authorization, by means of the identifier via the interface (110) with the transceiver unit, to access the transceiver unit. The product is considered authentic when the identifier matches the reference value.
