Abstract: A Method and a terminal intended for securing information in a local memory device which is couplable to a terminal having a data link interface. At the terminal, the method divides the original data resulting in a first portion and a second portion. The method stores the first portion in the local memory device and sends the second portion for storage in a remote memory device. Upon obtaining an authorized read request targeted to the original data the method retrieves the second portion and combines the two portions. The method provides high data security if the data, 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. The data may or may not be encrypted.

Abstract: A Method and a terminal intended for securing information in a local memory device which is couplable to a terminal having a data link interface. At the terminal, the method comprises the following steps. The method divides 801 original data included in the information to be secured, a division of the original data resulting in a first portion and a second portion. The method stores 802 the first portion in the local memory device and sends 803 the second portion via the data link interface for storage in a remote memory device. The method includes obtaining 804 an authorized read request targeted to the original data and responsive to the authorized read request reconstructs the original data. In more detail, the method retrieves 805 via the data link interface the second portion and combines 806 the second portion and the first portion which was stored in the local memory device.
