Predictive Authentication Resource Scheduling for Low-Power Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication methods for intelligent devices, such as automobiles, consume excessive power, reducing their operational duration and user experience due to the need for continuous resource allocation.
Innovation Solution
An authentication method that estimates the occurrence time and probability of authentication operations based on environmental and historical data, allowing for pre-starting of necessary hardware resources only when required, thereby reducing power consumption and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous hardware resource allocation is used for authentication, then authentication reliability is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary actions by predicting authentication needs based on historical data and environmental factors, pre-loading only the necessary authentication modules before they are actually needed. This allows the system to maintain high authentication reliability when needed while avoiding continuous resource allocation that would waste power.
Solution Approach 2:
The authentication system dynamically adjusts resource allocation based on real-time conditions, user behavior patterns, and environmental context. Instead of static continuous allocation, the system flexibly activates authentication resources only when prediction models indicate authentication is likely to be needed, resolving the contradiction between reliability and power consumption.
2Speed
If authentication hardware is kept active continuously, then authentication speed is improved, but device operational duration decreases
Solution Approach 1:
The system uses prediction algorithms to perform preliminary actions by identifying when authentication is likely to occur and pre-loading the necessary hardware resources and authentication data. This ensures fast authentication when needed while keeping hardware in low-power states otherwise, extending device operational duration.
Solution Approach 2:
Instead of continuous hardware activation, the system implements periodic checks and predictions to determine when authentication resources should be activated. This periodic approach maintains authentication speed by being ready when needed while significantly reducing power consumption during idle periods.
3Adaptability or versatility
If multiple authentication methods are always available, then authentication adaptability is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary analysis of user behavior, environmental context, and security requirements to predict which authentication method will be needed. Based on this prediction, only the necessary authentication module is loaded and activated, providing adaptability when needed while keeping the system simple during predictable low-complexity scenarios.
Solution Approach 2:
Different parts of the authentication system are activated with different levels of complexity based on local needs. Instead of always having all authentication methods available system-wide, the system selectively activates specific authentication modules (fingerprint, facial recognition, password, etc.) based on the specific context and user needs, reducing overall system complexity while maintaining adaptability.
Data Source
AI summary
An authentication method includes obtaining authentication environment information, and determining estimated information of an authentication operation of an intelligent device based on the authentication environment information and historical authentication data, where the estimated information includes an estimated occurrence time and an estimated occurrence probability that are of the authentication operation, and an authentication manner used for performing the authentication operation. In this way, a hardware resource related to the intelligent device can be pre-started based on the estimated information.
