Power Button Fingerprint Scanner for Fast Login
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing devices require users to wait for the operating system to load and the login screen to appear before they can provide their credentials, which slows down the login process.
Innovation Solution
Enabling users to scan their fingerprint using the power button to initiate the login process, allowing the device to automatically log on to their account without waiting for the operating system to load, by using a fingerprint scanner integrated into the power button and comparing the scanned fingerprint with stored fingerprints to authorize access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users provide credentials after the operating system loads and login screen appears, then the login process is secure and follows standard procedure, but the login time is extended due to waiting for OS initialization
Solution Approach 1:
The patent applies preliminary action by enabling fingerprint scanning at the power button during device initialization, before the operating system loads and the login screen appears. This allows the authentication process to begin in advance, eliminating the waiting time for OS initialization while maintaining security through verified fingerprint authentication.
2Ease of operation
If a fingerprint scanner is integrated into the power button, then the login process is simplified and accelerated, but the device structure becomes more complex
Solution Approach 1:
The patent applies merging by integrating the fingerprint scanner directly into the power button structure. This combines two functions (power control and fingerprint authentication) into a single component, simplifying the user operation to a single action while the internal integration manages the structural complexity.
Solution Approach 2:
The power button is designed with multi-functionality, serving both as a power control mechanism and as a fingerprint scanning interface. This universal design allows the same component to perform multiple functions, reducing the number of separate elements the user must interact with.
3Productivity
If fingerprint scanning is performed during OS initialization, then automatic login is achieved without waiting for the login screen, but the system must handle authentication before the OS is fully ready
Solution Approach 1:
The system performs preliminary fingerprint authentication during OS initialization before the login screen appears. This preliminary action establishes user identity early in the boot process, enabling automatic login to proceed without waiting for the full OS to load, thereby improving login speed while maintaining authentication reliability through verified fingerprint matching.
Data Source
AI summary
Example implementations relate to fingerprint scans with power buttons. For example, a computing device may include a power button and a processor. The power button receives a user input associated with an activation of the power button to turn on the computing device and scans a fingerprint associated with the user input while the computing device is initialized in response to the activation. The processor determines whether the fingerprint matches an authorized fingerprint from a database of stored fingerprints, identifies an account associated with the fingerprint when the fingerprint matches the authorized fingerprint, and provides a desktop environment associated with the account.
