| TITLE | Next-Gen Android Security |

| ABSTRACT | With the rapid growth of smartphone usage, Android devices today handle vast amounts of ––personal, financial, and confidential information, making robust authentication mechanisms essential to protect users from increasingly sophisticated cyber threats. Traditional methods such as PINs, passwords, and pattern locks provide only basic protection and remain vulnerable to brute-force attempts, shoulder surfing, phishing, and unauthorized system-level access. To overcome these limitations, this paper introduces an Next-Gen Android Password Security System that employs a comprehensive, multi-layered authentication framework combining password hashing, secure hardwarebacked verification, biometric authentication. Whenever a user enters a credential, it is immediately converted into a cryptographic hash and verified inside the Trusted Execution Environment (TEE) [2], ensuring that sensitive information never leaves the protected hardware zone. Simultaneously, biometric identifiers such as fingerprints or facial features are matched through encrypted templates stored in the Android KeyStore[6], ensuring resistance to spoofing and data leakage. Complementing these mechanisms, the system continuously evaluates the biometrics and other authentications. Access is granted only when all authentication layers validate successfully, after which the system releases the decryption keys required to unlock the device or corresponding application data. By integrating cryptographic protection,and biometrics into a unified workflow, the proposed framework offers a resilient, tamper-resistant, and future-ready authentication model for the Android ecosystem [1]. This multifaceted approach significantly improves device security, reduces the risk of unauthorized access, and provides a more reliable and scalable solution compared to conventional Android security techniques, making it suitable for individual users, enterprise environments, and next-generation mobile security applications. |
