Portable Device Data Transmission Control for Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods require extensive personnel and reveal unnecessary personal data, as they often necessitate manual verification and disclosure of sensitive information for access control, especially in high-security areas.
Innovation Solution
A method utilizing a portable device with multiple interfaces that allows users to control which data is transmitted to a control device via specific interfaces, ensuring only necessary data is shared for authentication, and allowing users to define access conditions and security protocols independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual authentication with ID cards is used, then authentication can be performed, but personnel costs increase and personal data must be revealed
Solution Approach 1:
The authentication system performs self-service by using automated control devices that verify personal data without requiring manual inspection by border guards or security personnel. The portable device automatically transmits and verifies authentication data, eliminating the need for human operators to manually check ID cards while maintaining authentication reliability.
2Reliability
If all personal data is transmitted for authentication, then authentication completeness is ensured, but user privacy is compromised
Solution Approach 1:
The system extracts and transmits only the specific personal data elements required for authentication purposes, rather than transmitting all personal data. The control device requests only necessary information (such as authentication credentials and minimal identifying data), leaving sensitive personal information retained on the portable device or not transmitted at all, thus maintaining user privacy while ensuring authentication completeness.
Solution Approach 2:
Different levels of data transmission are applied based on the specific authentication context. The system transmits different amounts and types of personal data depending on the security requirements and authentication level needed, rather than uniformly transmitting all personal data in every authentication scenario. This allows authentication completeness to be maintained at each level while minimizing privacy loss.
3Adaptability or versatility
If multiple interfaces are used for data transmission, then communication flexibility is improved, but device complexity increases
Solution Approach 1:
The portable device is designed with multiple communication interfaces (such as contactless RFID/NFC, contact-based smart card interfaces, and wireless communication capabilities) that can function universally across different authentication scenarios and control devices. This multi-functionality allows the single portable device to adapt to various communication protocols and physical interfaces, providing communication flexibility without requiring multiple separate devices.

AI summary
The invention relates to a method for transmitting data regarding an individual (104) to a control device (100), the individual carrying a device (102). Said device comprises at least first and second interfaces (118, 140) for communication with the control device, configuration data (146) on the device determining via which of the first and second interfaces first data (144) may be transmitted, and the configuration data being definable by the user. The device carries out the following steps when approaching the control device: receiving a first inquiry (136) from the control device via the first interface, the control device inquiring the first personal data from the device by way of the first inquiry; accessing the configuration data; checking whether the first data may be transmitted via the first interface, a necessary respective requirement being that the configuration data allow transmission of the data via the first interface; transmitting the first data to the control device via the first interface if the first data may be transmitted via the first interface.
