Digital Watermark Fundus Projection for Secure App Startup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for starting applications on electronic devices are inconvenient and insecure, particularly when multiple users need to access different environments, as they often require complex login processes and are not optimized for rapid or secure access.
Innovation Solution
A user information acquisition method and apparatus that utilizes digital watermarks to extract application startup information, projecting this information to the user's fundus for secure and rapid application initiation, leveraging wearable devices like smart glasses to visualize and authenticate user-specific data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users log in to different user environments by using different user names and passwords, then different user environments can be accessed, but the process is not convenient enough and secure enough
Solution Approach 1:
The patent extracts the authentication information from the traditional login process and embeds it into digital watermarks within images. Instead of requiring users to manually enter usernames and passwords, the system extracts authentication data from watermark-embedded images, making the login process more convenient while maintaining security through the hidden nature of watermarks.
Solution Approach 2:
The patent introduces digital watermarks as an intermediary between the user and the authentication system. The watermarks serve as a mediator that carries authentication information within images, allowing users to authenticate by interacting with images rather than directly entering credentials, thus improving both convenience and security.
2Reliability
If traditional screen locking functions are used to save energy and avoid misoperations, then security is improved, but users need to unlock the screen first before starting applications, which reduces efficiency
Solution Approach 1:
The patent performs preliminary authentication by embedding authentication information in digital watermarks within images that users interact with during normal usage. This allows the system to authenticate users before the traditional screen lock is engaged, enabling faster application startup without compromising security, as the watermark-based authentication has already verified user identity.
3Ease of operation
If different gestures are used to start different application programs, then application startup is enabled, but it is difficult to remember the gestures and users cannot be differentiated, which reduces security
Solution Approach 1:
The patent applies local quality by embedding unique authentication information specific to each user within digital watermarks in images. Instead of using generic gestures that all users must remember, each user has customized authentication data embedded in images they interact with, making the authentication both user-specific (improving security) and integrated into the visual interface (maintaining ease of operation).
Data Source
AI summary
