Landex: Blockchain-Based Land Registration System

In today’s digital age, ensuring the use of strong and unique passwords across various online platforms hasbecome a vital aspect of cybersecurity. Despite this need, research shows that many users still rely on weakor repeated passwords due to the difficulty of remembering complex ones. Although cloud-based passwordmanagers help by securely creating and storing passwords, they come with potential downsides such asunauthorized access, data breaches, and reliance on third-party services. To tackle these issues, this studyintroduces an offline Android-based password manager that operates without an internet connection tosafely generate and store passwords. The application allows users to create high-entropy, random passwordstailored to specific preferences, including length, use of symbols, numbers, and letter cases. It also functionsas a secure vault to store login details, usernames, and personal notes in an encrypted and hidden format. Incontrast to cloud-based tools, this offline solution uses AES encryption along with Android’s SharedPreferences for secure local data storage, preventing unauthorized access. An internal authentication systemadds an extra layer of security by allowing access only to verified users. This project analyzes commonpassword security issues, the use of encryption, and the reliability of offline storage in comparison to cloudservices. Results demonstrate the offline manager’s strengths, highlighting its improved security, minimizedcyber threat exposure, and strong privacy safeguards. The goal is to promote the use of robust passwordhabits through a reliable, user-friendly, and privacy-focused alternative to conventional password managers
