Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in accessing target services or external devices due to reduced authentication rates in varying environmental conditions, such as direct sunlight or darkness, and require multiple types of authentication for different services, making the authentication process cumbersome and inefficient.
Innovation Solution
An electronic device equipped with multiple sensors, including a camera, fingerprint sensor, microphone, inertial sensor, touch sensor, and illumination sensor, generates authentication information and calculates a final security level score to determine accessibility, allowing for multi-factor authentication and efficient access to services or external devices, with the ability to update scores in real-time and request additional authentication as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If iris recognition is used for authentication, then authentication speed is improved, but authentication reliability deteriorates in the presence of direct sunlight
Solution Approach 1:
The electronic device integrates multiple authentication methods (iris recognition, face recognition, fingerprint recognition) into a single authentication system. The controller can select and switch between different authentication methods based on environmental conditions, service security requirements, and sensor availability, making the authentication system universal and adaptable to various scenarios.
2Speed
If face recognition is used for authentication, then authentication speed is improved, but authentication reliability deteriorates in a dark place
Solution Approach 1:
The authentication system dynamically adjusts the authentication method based on environmental conditions detected by sensors. When the illumination sensor detects dark conditions, the controller switches from face recognition to alternative authentication methods such as fingerprint recognition or iris recognition, ensuring reliable authentication regardless of lighting conditions.
Solution Approach 2:
The system uses feedback from illumination sensors and other environmental sensors to determine the appropriate authentication method. The controller continuously monitors environmental conditions and adjusts the authentication approach accordingly, creating a closed-loop system that maintains high reliability in varying conditions.
3Reliability
If multiple types of authentication information are required for different services, then security level is improved, but operation complexity deteriorates
Solution Approach 1:
The electronic device implements a universal authentication system that can provide multiple security levels using a single integrated authentication module. The controller automatically selects the appropriate authentication methods and combinations based on the security requirements of different services, eliminating the need for users to manually configure different authentication types for each service.
Solution Approach 2:
The authentication system operates autonomously by automatically determining the required authentication level and selecting appropriate authentication methods without user intervention. The controller evaluates service security requirements and environmental conditions, then autonomously executes the appropriate authentication sequence, reducing operational complexity for users.
4Reliability
If multi-factor authentication is implemented, then security level is improved, but device complexity deteriorates
Solution Approach 1:
The patent combines multiple authentication methods (iris, face, fingerprint recognition) and multiple sensors (camera, illumination sensor, fingerprint sensor) into a single integrated authentication system. The controller统一管理 (unified management) the coordination of these components, consolidating what would otherwise be separate authentication systems into one cohesive unit, thereby reducing overall device complexity while maintaining multi-factor authentication capabilities.

AI summary
Disclosed is an electronic device including: an input unit including buttons; a plurality of sensors; and a controller configured to generate at least one authentication information based on at least some of the plurality of sensors, calculate a final security level score based on a security level score corresponding to the at least one authentication information, and determine whether a target service or a target external device is accessible, depending on the final security level score, wherein the security level score is set differently based on a type of the at least one authentication information. Accordingly, it is possible to easily access the target service or the target external device through multi-factor authentication.
