Abstract: The invention relates to a method and to a device for transmitting decryption codes for freely transmitted, encrypted program contents, enabling decryption codes to be transmitted in a more simple manner and enabling a connection or a user to be established via a user network, also enabling the reception of a telephone call, identification of the network termination element, especially the telephone number, and transmission of the decryption code for a program content. Billing data can be automatically established using the network termination element/the telephone number and information on the requested program content. Additionally or alternatively, examination is possible if a registered right of access for the decryption code exists for the network termination element/telephone number, whereby transmission occurs exclusively for the existing right of access. The invention also relates to a system for decrypting freely transmitted, encrypted program contents.

Abstract: The aim of the invention is to permit the automatic identification of access rights to protected areas in networks, in particular on the Internet. This is achieved by a method for automatically identifying the access rights to protected areas in a first network using a unique connection identifier of a second network, in particular in the interconnection of networks that constitutes the Internet.
