A REAL-TIME PARENT-CHILD CONSENT PLATFORM FOR SECURE APPLICATION ACCESS USING MQTT AND JWT.

Children are using apps more for learning, playing games, and chatting. This can create problems. They may spend too much time on screens. Their privacy may be at risk. They might see content that is not suitable. Most parental control tools use fixed rules.Some tools block apps completely, while others rely on strict time limits. These controls are simple but not flexible and do not always meet the needs of children or parents. These tools are not flexible and do not let parents respond in real time. They also do not involve children in making decisions. This paper introduces a real-time Parent–Child Consent Platform. Children can ask for permission before using apps. Parents can approve or deny the requests right away. The system uses MQTT to send messages fast between the child and parent screens. JWT is used for login. Only users who are allowed can log in. For the screen the user sees, we use React and Next.js. The server side works with Node.js and Express. MongoDB keeps the data. Tests show the system works well. Requests are handled in real time. Access is kept secure. Parents can see what their children are doing more clearly. By combining fast interaction with secure login, this platform provides a practical and easy-to-use solution for managing children’s app access.
