A method for ciphering multimedia includes the entering of an ciphering index in a definition data block of the multimedia data, this index pointing to an ciphering algorithm which is to be used. In response to the ciphering index in the definition data block one of a plurality of ciphering algorithms is selected. The multimedia data are ciphered using the selected ciphering algorithm. Various additional entries in the definition data block which is assigned to the multimedia data permit the clearing or enabling of a deciphering device, rapid access to a database of ciphered multimedia data and a customer- and data-specific use of the multimedia data while taking copyright aspects into account. |
