Skin-Based User Authentication Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle authentication systems require interaction with a mechanical key or keyless entry systems that consume high energy and are inconvenient, as they necessitate the user to search for the key or engage in a question-answer dialog to verify authorization.
Innovation Solution
A method and system that injects a signal into a user's skin using a transmitting device, allowing direct contact with a receiving device to authenticate the user, eliminating the need for a mechanical key and reducing energy consumption by using the skin as a signal transmission medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical key or keyless entry system is used for vehicle authentication, then the user can access the vehicle, but the user must search for the key or engage in a question-answer dialog which consumes high energy and is inconvenient
Solution Approach 1:
The patent extracts the authentication function from traditional key-based systems and embeds it directly into the user's skin through a transmitting device. This eliminates the need to search for external keys or engage in energy-consuming question-answer dialogs, as the authentication signal is now inherently present in the user's body.
Solution Approach 2:
The patent introduces the user's skin as an intermediary medium for signal transmission. The transmitting device injects authentication signals into the skin, which then serves as a natural communication channel between the user and the vehicle's receiving device, eliminating the need for separate key devices or high-energy wireless communication protocols.
2Ease of operation
If electromagnetic fields are used for keyless entry authentication, then contactless access is enabled, but high energy consumption occurs and electromagnetic field setup is required
Solution Approach 1:
The patent replaces electromagnetic field-based authentication with a mechanical/biological approach by using the user's skin as a signal transmission medium. This substitution eliminates the need for high-energy electromagnetic field generation while maintaining authentication functionality through direct physical contact between the skin and the vehicle's receiving device.
3Reliability
If traditional authentication systems are used, then security can be provided, but the system complexity increases due to mechanical keys or keyless entry requirements
Solution Approach 1:
The patent makes the user's skin a universal authentication medium that can serve multiple functions: it stores authentication signals, transmits them to the vehicle, and eliminates the need for separate key devices. This multi-functionality reduces system complexity while maintaining security, as the authentication capability is now inherent to the user rather than requiring external devices.
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
Enhances security and convenience by allowing authentication through skin contact, reducing energy expenditure, and enabling secure access to vehicles without active user actuation, while potentially avoiding the need for electromagnetic field setup.
Implementation Method 1
A signal which comprises an item of information relating to the user is injected into skin of the user by means of a transmitting device
Data Source
AI summary
A method for authenticating a user with respect to a facility, for example, with respect to a vehicle. A signal having an item of information relating to the user is injected into skin of the user by a transmitting device. Direct contact is established between the skin of the user and a receiving device assigned to the facility, with the result that the signal is transmitted from the skin of the user to the receiving device. The user is also authenticated based on the signal received by the receiving device.
