An arrangement is described for protecting items of information of a database against use without permit from the proprietor of the rights. By rendering meaningless an item of information in the database which is not to be exploited without permission, by encrypting or otherwise corrupting, or moving from the database to a storage location hidden to the user a function associated with the item of information for the control of the interpretation and presentation thereof to a user by a computer, this function becomes unavailable for the utilization in the computer of the user and hence, the corresponding item of information cannot be correctly interpreted. Thus, it will be possible to exploit such selected items of information stored in a database only with a corresponding authorization. |
