In recent times, digital locks have become increasingly popular for securing homes and valuables. However, these locks can still be vulnerable to picking or disabling by those with the necessary skills or tools. To address this issue, this project proposes the use of blockchain technology and biometrics or smartphones to create a more secure system for home security. By leveraging the decentralized and tamper-proof nature of blockchain, combined with biometric identification or smartphone authentication and using the power of IOT technology, homeowners can ensure that their property remains secure and protected from unauthorized access. This project offers a novel solution to the problem of digital lock vulnerabilities, with potential applications in the fields of home security and asset protection.
