Biometric Authentication for Seamless Cross-Device Game State Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for user authentication in mobile games are intrusive and not seamless, leading to a significant number of users exiting the game and not returning, as they disrupt the gaming experience with login requests.
Innovation Solution
A system and method using biometric identifiers or wearable devices to authenticate users across applications and devices, allowing seamless reinstallation of games with restored state information and synchronized progress, ensuring only the rightful user accesses and continues their game progress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional login requests are presented to users in mobile games, then user authentication security is improved, but user retention deteriorates due to intrusive interruptions
Solution Approach 1:
The patent replaces traditional mechanical login prompts with biometric authentication systems (fingerprint sensors, facial recognition cameras) and wearable device integration (NFC, Bluetooth). This substitution eliminates intrusive login interruptions while maintaining security, as biometric data provides reliable user verification without requiring manual login actions that interrupt gameplay
Solution Approach 2:
The system implements self-service authentication where the user's biometric characteristics or wearable device automatically verify their identity without requiring active participation. The authentication occurs seamlessly in the background, allowing users to resume games without manual login actions, thus improving retention while maintaining security
2Ease of operation
If seamless authentication is implemented using biometric identifiers, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal authentication framework that supports multiple biometric modalities (fingerprint, facial recognition, iris scan) and wearable device types (smartwatches, fitness trackers, NFC tags) through a single integrated system. This multi-functionality approach consolidates various authentication methods into one unified solution, improving ease of operation while managing device complexity through standardized interfaces and protocols
3Adaptability or versatility
If user state information is restored across devices, then adaptability is improved, but data synchronization complexity increases
Solution Approach 1:
The patent introduces a cloud-based server as an intermediary that manages data synchronization between multiple devices. The server stores user state information, game progress, and biometric authentication data, acting as a central hub that automatically synchronizes data across devices. This intermediary approach simplifies the synchronization process by centralizing data management rather than requiring direct peer-to-peer communication between devices, thus improving adaptability while managing complexity
