Lock Screen Biometric Authentication for Selective Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computing devices with lock screens restrict information and functionality access, posing a trade-off between security and user convenience, as unauthorized access can occur if personal information is displayed, while locking the device prevents easy access for authorized users.
Innovation Solution
Implementing a biometric user authentication process to determine a measure of confidence in the authorized user, allowing selective display of personal information and functionality on the lock screen based on this confidence level, enabling authorized users to access information without unlocking the device while preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If personal information is displayed on the lock screen, then user convenience is improved, but security deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the lock screen into multiple display regions with different security levels. Personal information is displayed in a first region that is accessible without authentication, while sensitive information is placed in a second region that requires biometric authentication. This allows the system to provide convenient access to non-sensitive information while maintaining security for sensitive data, resolving the contradiction between user convenience and security.
2Reliability
If biometric authentication is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The patent segments the authentication process into distinct levels: a first level that provides access to non-sensitive information without authentication, and a second level that requires biometric authentication for sensitive information. This segmentation allows the device to implement biometric security only where necessary, rather than requiring it for all lock screen functions, thereby improving security for critical data while minimizing the increase in device complexity.
3Reliability
If multiple authentication levels are implemented, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent extracts and separates sensitive information from the general lock screen display. By placing sensitive information in a dedicated second region that requires authentication, while keeping non-sensitive information accessible in a first region, the system provides immediate access to commonly needed information without requiring users to go through biometric authentication, thus maintaining ease of operation for routine tasks while enhancing security for sensitive data.

AI summary
A computing device is described that selectively displays or suppresses personalized information on a lock screen based on the results of a biometric user authentication process. In embodiments, a measure of confidence that a user of the computing device is an authorized user is determined based on biometric data collected by one or more biometric sensors. If it is determined that the measure of confidence satisfies a criterion, then personal information associated with the user is selectively rendered to the lock screen while the computing device is in the locked state. If it determined that the measure of confidence does not satisfy the criterion, then such personal information may be suppressed from the lock screen. The application of the foregoing technique to selectively provide or deny access to certain functionality of the computing device via the lock screen is also described.
