Project Lifeline: Biometric Security Ecosystem for Lock-Screen Password Recovery
Title: Project Lifeline: Biometric Security Ecosystem for Lock-Screen Password Recovery Overview The Lifeline application is a proactive biological and digital security ecosystem specifically designed to protect smartphone users from data loss and the erasure of personal memories caused by forgetting the screen lock code (PIN/Password). How it Works • Secure Registration: While the phone is unlocked, the user registers their name, phone number, and email, and securely saves their screen lock code in an encrypted format within the isolated system vault (SecureStore). • Persistent Notification: This immediately generates a persistent, silent notification in the notification drawer that functions even when the screen is locked with a password and automatically restarts upon device boot. • Emergency Rescue: In the event of an emergency when the code is forgotten, the user simply pulls down the notification drawer from the lock screen and taps the rescue button. Identity Verification & Decryption The application invokes the phone’s biometric security system (face scan or fingerprint) or the "System Credential Fallback" (such as a backup code or a secret security question) to ensure maximum privacy protection and block intruders. Once identity verification succeeds, the app decrypts the code and displays it instantly on the screen inside the app, allowing the user to unlock their device in seconds, at zero material cost, and without the need for an enforced factory reset or losing any files
