Solution Overview

Problem

Users face inconvenience when trying to access locked content on digital devices, as they need to undergo additional authentication procedures such as inputting passwords or passing authentication processes to unlock the content.

Innovation Solution

A method that allows users to access locked display pages on digital devices by collecting authentication information through user input, determining whether to provide the locked page based on the collected information, and offering alternative pages if access is denied, ensuring seamless content access without additional authentication for permitted users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If content is locked to restrict access to authorized users only, then user privacy and content security are improved, but additional authentication procedures are required which cause user inconvenience

Engineering Contradiction:
Improvecontent securityVSAvoiduser convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary authentication by detecting fingerprint information before the user attempts to access locked content. The fingerprint sensor captures authentication data in advance, and the controller determines authorization status before content access is requested, eliminating the need for additional authentication steps during content usage

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses the user's own fingerprint information, which is automatically captured when the user interacts with the device, to authenticate and grant access to locked content. The user's biometric data serves as both the identifier and authentication credential, allowing seamless access without external authentication mechanisms

Inventive Principle:
Principle #25Self-service

2Loss of time

If fingerprint authentication is integrated into the display module, then authentication speed and user convenience are improved, but device complexity increases

Engineering Contradiction:
Improveauthentication timeVSAvoiddevice structure
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The fingerprint sensor is integrated directly into the display module, merging the authentication function with the existing display structure. This combination allows the display module to perform both display and fingerprint sensing functions, reducing the need for separate authentication hardware and minimizing structural complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The display module is designed to serve multiple functions: it acts as both the visual display interface and the fingerprint sensing interface. By making the display module universal, the system eliminates dedicated authentication components and reduces overall device complexity while maintaining fast authentication capability

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A method for controlling display of content, the content including a plurality of display pages of a sequence, the method comprising: displaying a first display page on the display screen, receiving a first user input for changing from the first display page to a second display page of the content, the second display page being a neighboring display page of the first display page in the sequence, detecting the second user input when the second display page is a locked display page, extracting the fingerprint information from the second user input when the second user input is detected, and displaying the second display page when the second display page is accessible based on the fingerprint information or a third display page when the second display page is not accessible based on the fingerprint information.
