Bluetooth Key Proximity Authentication for Automatic Device Login
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face the inconvenience of needing to manually input commands or authenticate to perform operations on devices, lacking a system to automatically initiate actions upon proximity with a key.
Innovation Solution
A key with integrated communications circuitry creates a short-range personal area network, allowing it to remotely control host devices by broadcasting identification and instructions, enabling automatic operations such as logging in, loading user profiles, or activating devices when in proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input is required to perform device operations, then device control is achieved, but user convenience and operation speed deteriorate
Solution Approach 1:
The system performs preliminary actions by pre-establishing user profiles and device associations. When a user approaches a device with their key, the system has already prepared the authentication credentials and operation parameters, enabling automatic login and profile loading without requiring the user to manually input anything during the actual operation.
Solution Approach 2:
The patent replaces the mechanical manual input system (pressing keys, typing passwords) with an automatic wireless communication system. The key device automatically transmits identification signals via Bluetooth or similar wireless technology, and the host device automatically processes authentication and executes operations, substituting the manual mechanical interaction with an automated electronic system.
2Extent of automation
If automatic operation upon proximity is implemented, then user convenience improves, but system complexity and security risks worsen
Solution Approach 1:
The key device is designed as a universal multi-functional tool that can work with multiple different host devices (computers, televisions, appliances, vehicles) using the same basic mechanism. The host devices also incorporate universal authentication protocols, allowing the system to maintain simplicity through standardized interfaces while supporting diverse applications.
Solution Approach 2:
The key device serves as an intermediary that simplifies the interaction between the user and the host device. Instead of the user directly interacting with complex device interfaces or security systems, the key mediates by automatically handling authentication, profile retrieval, and operation initiation, thereby reducing the perceived complexity for the user.
3Productivity
If automatic login and profile loading are enabled, then operation speed improves, but security requirements and authentication complexity worsen
Solution Approach 1:
The system creates a digital copy of the user's authentication credentials and profile information stored in the key device. Instead of requiring the user to remember and manually enter complex passwords each time, the authenticated user profile is copied to the key during initial setup, enabling rapid automatic authentication while maintaining security through encrypted storage and transmission of these credential copies.
Solution Approach 2:
The system implements feedback mechanisms where the host device verifies the key's authentication credentials and provides confirmation signals. The key and host device engage in a challenge-response authentication protocol where each device verifies the other's identity before allowing automatic operations, ensuring security through continuous mutual verification rather than simple one-way authentication.

AI summary
This application is directed to a system for remotely directing a host device to perform an operation using a key. The key may include a communications circuitry for transmitting data, for example a key identifier or an instruction to perform an operation, within a personal area network created by the communications circuitry. When a host device is within the personal area network, the key may transmit data received by a transceiver on the host device. In response to receiving the data, the host device may perform an operation (e.g., an authentication operation). In some embodiments, the key may transmit data identifying an operation for the host device to perform. In some embodiments, the host device may store in memory key identification information and an associated operation which may be retrieved when the key is brought in proximity of the host device.
