The medium (1) has a set of instructions for storing data sets in a memory (5) i.e. non volatile memory. The medium is arranged for writing data into the data sets in a standard mode and in a personalization mode. The check total of the respective data sets is updated in the standard mode after each write access. Write accesses are implemented without following updation of the check total in the personalization mode during a write phase. An updation of the check totals for the data set is executed during a security phase, where the data set is changed in the write phase. An independent claim is also included for a method for personalizing a portable data storage medium. |
