Data i.e. digital data stream, broadcasting securing method for data base of e.g. flash memory card, involves reconstituting digital data file from cut files and identification parameter by fixed or mobile terminal

摘要

The method involves cutting a digital data file into two files that are cut from a cutting point by processing units (13) of a server (3). The cut files and an identification parameter from the point are separately stored in a database (14) connected to the server. The cut files and the parameter are transmitted to a processing unit i.e. fixed or mobile terminal (2), where the terminal comprises communication units (6). The digital data file is reconstituted from the cut files and the parameter by the terminal. An independent claim is also included for a data broadcasting securing system comprising a data base.
