Abstract

Videotex subscriber identification via a videotex database which can be dialled up via the public switched network is carried out using a personalised secret code word which is requested by the database. The code word is stored and prepared in the subscriber's videotex unit it is then transmitted to the database and evaluated therein. If a valid code word is not recognised, the procedure is repeated or the connection is cleared down. The code word can be programmed by the subscriber. The method offers high security against manipulation and is simple to use.
