Fingerprint-Authenticated Ring Charger for Secure Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices often lack secure data transfer mechanisms, allowing unauthorized access to sensitive user data via insecure wireless connections, and there is no effective verification of data ownership during transfer.
Innovation Solution
Incorporating a fingerprint scanner into a wearable device charger to authenticate the user before allowing data transfer, using technologies like capacitance, optical, or ultrasonic sensors to verify identity and ensure secure data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless connection is used for data transfer, then data exchange convenience is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The system performs preliminary authentication actions before allowing data transfer. The fingerprint sensor captures and verifies the user's biometric data before establishing or enabling the wireless connection for data exchange, ensuring that only authorized users can access the transfer function
Solution Approach 2:
The authentication system acts as an intermediary between the user and the wireless data transfer function. It verifies the user's identity through fingerprint recognition and controls whether the wireless connection should be established or activated for data exchange, mediating between security requirements and convenience
2Device complexity
If no authentication mechanism is implemented, then device complexity is reduced, but data ownership verification capability deteriorates
Solution Approach 1:
The system replaces complex mechanical or manual authentication mechanisms (such as physical keys, passwords, or multiple verification steps) with a biometric fingerprint recognition system. This provides reliable data ownership verification while maintaining relatively simple device architecture through the use of optical or capacitive sensing technology

AI summary
Methods, systems, and devices for a wearable ring device charger that features a fingerprint scanner to increase security of the sensitive data are described. For example, the wearable ring device may store sensitive health data or other sensitive data. A user may protect the sensitive data by preventing the data from being uploaded (e.g., from the wearable ring device to the charger or to the smart device application) until a fingerprint scan is performed. A fingerprint scanner of the charger may include one or more of a capacitance reader, an optical sensor (e.g., a camera), or an ultrasonic sensor to sense data associated with the fingerprint of the user. In some examples, the wearable ring device may store fingerprint data associated with the user to allow the user to scan the wearable ring device in lieu of scanning a physical fingerprint.
