DETAILED DESCRIPTION Therefore, it is an object of the present invention to provide an interactive multimedia personal service system in which a user utilizes a smart-card activated and enabled remote control device to interact with a service provider, via a set-top box, utilizing respective transmission paths, to securely request and receive subscriber content data.
The present invention relates to an interactive subscriber content data system which provides secure interaction between a user's remote control device, a set-top box and a service provider.
An end user of the system holds a remote control device which may be a system-specific remote control device or a personal hand-held device, a hand-held pager or a wireless telephone.
The remote control device provides secure transmissions for requests of subscriber content data since the remote control device is activated by the insertion of a user's personalized smart card into a reader which has contacts which contact corresponding contacts on a surface of the smart card.
The smart card includes a security chip which includes personalized identification information for activating the remote control device, and further includes both a public key and a private key for encryption and decryption purposes, respectively.
After the user has activated the remote control device by inserting his or her personalized smart card into the reader, the user enters a request for subscriber content data using a key-pad or a smart touch pad on the remote control device.
The request for subscriber content data as well as the user's public key, which is stored on the user's smart card, are then transmitted to the service provider over a first transmission path which is a two-way transmission path which includes a short message service (SMS).
In response to the request for subscriber content data from the user's remote control device, the following embodiments are provided, although the invention is not at all limited thereto.
In a first response embodiment, the service provider receives the user's transmitted public key, encrypts a secret key corresponding to the service provider, and transmits the encrypted secret key corresponding to the service provider back to the remote control device, via the same two-way connection between the remote control device and the service provider on which the request for the subscriber content data was originally transmitted
