An electronic device is connectable to an information processing apparatus and includes a reading unit to read biologic information; an authentication unit to authenticate a user based on the biologic information; a storage unit including (i) a first storage area that is accessible from the information processing apparatus after authentication has been successfully performed and that stores data supplied from the information processing apparatus with the data being encrypted and (ii) a second storage area storing software that is executed by the information processing apparatus and that has a function of restricting an output destination of data read from the first storage area; a decrypting unit to decrypt the data stored in the first storage area and output the data to the information processing apparatus; and a control unit to control whether the decrypting unit is allowed to decrypt the data in response to instructions from the information processing apparatus.
