Biometric Combination Lock for Secure App Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current software applications require users to reveal their identity and personal information for personalized services, leading to issues like profile management difficulties, fake identities, privacy risks, and misuse of personal data for targeted advertising, with inadequate control over data usage and storage.
Innovation Solution
A system and method utilizing a biometric combination lock for authenticated access, where users register with a set of biometric expressions, generating Secret-Keys and Public-Keys for secure authentication without revealing their identity, using a processor and memory to capture and process biometric samples, and store Unique-Numbers and Public-Keys on user devices and storage devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users provide identity and personal information for personalized services, then application functionality and personalization are improved, but user privacy and security are worsened
Solution Approach 1:
The patent introduces a biometric combination lock as an intermediary authentication mechanism between the user and the application. Instead of directly providing personal information to the application, the user authenticates through biometric factors (fingerprint, facial recognition, etc.) which are processed through the lock mechanism. This intermediary layer enables personalized services while preventing direct exposure of user identity and personal data to the application server, thereby resolving the contradiction between personalization and privacy protection.
2Adaptability or versatility
If users create multiple profiles for different applications, then access to various services is enabled, but profile management difficulty increases
Solution Approach 1:
The biometric combination lock serves as a universal authentication mechanism that can be applied across multiple different applications. Instead of requiring separate profiles and authentication methods for each application, the system uses a single biometric-based lock that provides consistent authentication across all applications. This multi-functional approach enables users to access various services while maintaining a single, manageable authentication profile, thereby reducing profile management complexity.
3Ease of manufacture
If applications collect personal information for functionality, then service capability is improved, but data misuse for advertising increases
Solution Approach 1:
The patent extracts and separates the authentication function from the personal information collection function. The biometric combination lock handles only the authentication aspect, verifying user identity without collecting or storing personal information about the user's preferences, behavior, or demographics. By taking out the authentication function and isolating it from data collection mechanisms, the system enables applications to function while preventing the collection and misuse of personal data for advertising purposes.
4Duration of action of stationary object
If platforms store user activity data permanently, then data availability is improved, but user control over data is worsened
Solution Approach 1:
The biometric combination lock implements self-service authentication where the user maintains control over their own identity verification. The lock mechanism is stored on the user's device and uses their biometric factors to authenticate, eliminating the need for platforms to permanently store and manage user activity data. This self-service approach ensures data availability for authentication purposes while giving users complete control over their data, as the authentication capability resides with the user rather than the platform.
Data Source
AI summary
A system and method for enabling a user to obtain authenticated access to an application using a biometric combination lock. The system is configured for registering a user by receiving a set of biometric expressions and a set of biometric samples of the user, corresponding to two or more biometric factors associated with each biometric expression. Further, the method includes steps of processing the set of biometric samples to compute a Secret-Key (S1) corresponding to the user, generating a Unique-Number (N1) using a random number generation algorithm, applying a Function (F1) to the Secret-Key (S1) and the Unique-Number (N1), to compute a Public-Key (P1).
