Home Information Machine Registration via Mobile Internet Device Mediator

The patent introduces a new intermediary component called the MID (Mobile Internet Device) that acts as a mediator between the DECT sub-machine and the DECT fixed phone. The MID stores verification information and controls the registration process, preventing direct access between sub-machines and the fixed phone. This intermediary structure maintains registration simplicity while significantly improving security by preventing illegal users from directly obtaining verification information.

The patent implements a feedback mechanism where the MID module actively monitors and manages registration information. When a DECT sub-machine needs to be unregistered, the MID receives unregistration information and sends feedback signals to both the DECT fixed phone and the sub-machine itself. This feedback loop ensures that the home information machine maintains effective control and management of all DECT devices, preventing unauthorized access while keeping the process user-friendly.

The MID serves as a secure intermediary that stores verification information separately from the DECT fixed phone. This intermediary structure maintains relative system simplicity while introducing a security layer that prevents illegal users from directly accessing verification information. The MID controls all verification processes, ensuring that even if verification information is compromised, the DECT fixed phone cannot be directly accessed by unauthorized devices.

The MID acts as a controlled intermediary that manages password modification operations. When a DECT sub-machine requests to modify its registration password, the MID verifies the request through authentication protocols before allowing the change. This intermediary control ensures that only authorized operations are permitted, maintaining usability for legitimate users while preventing security compromises from illegal attempts to modify passwords.
