Landex: blockchain-based land registration system

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