The method includes obtainingan authorized read request targeted to the original data and responsive to the authorized read request reconstructs the original data. In more detail, the method retrievesvia the data link interface the second portion and combinesthe second portion and the first portion which was stored in the local memory device. The method provides very high data security if the data, from which the second portion is removed, is encrypted prior to the step of dividing. Another aspect of the invention comprises a terminal capable of at least combing the first and second data portions to reconstruct the original data, and preferably to perform the step required for dividing the data.
