DATA PROCESSOR, METHOD OF DATA PROCESSING, PROGRAMME AND DATA CARRIER

摘要

FIELD: physics, computer engineering.SUBSTANCE: invention relates to data processing procedures. Device allows reading application program from data carrier whereon written is application program as a content. It comprises first root certificate released for application program and second root certificate released before release of said first root certificate for application program. It can execute said application program. Note here that said processor comprises generator of first folder to store first folder of data to be processed by application program. Note here that first folder is related to said first root certificate. It comprises means to copy data stored in second folder to said first data folder. Note also that second folder is related to second root certificate in case second folder is available in memory unit.EFFECT: higher data processing speed.10 cl, 19 dwg
