Describe the add-ons or changes you've made 📃

The file locking mechanism using facial recognition ensures that sensitive files on a system can only be accessed by authorized users whose identity is verified through facial recognition. This feature leverages Haar cascades and LBPH, to recognize a user's facial features and either grant or deny access based on the authentication result.
