In a system to realize prevention of leakage and loss of confidential information by inhibiting writing into a secondary storage device or writing into external storage media, created confidential data is archived by a secure method without being lost if communication is not available and a file server cannot save the information. For this purpose, first, a designated folder is created on a non-volatile storing memory being built in a mobile terminal and created confidential data is saved in the folder. Then, a filter driver controls access to the designated folder to prevent leakage of information by an application in a mobile phone by a malicious user. Further, a function to remove data in the designated folder in the mobile terminal from a mobile terminal management server through a telephone network prevents loss of saved confidential data due to loss of the mobile terminal.
