PROGRAM DATA CHANGE PROTECTING APPARATUS AND PROGRAM DATA CHANGE PROTECTING METHOD

摘要

In the present invention, disclosed are a program data change protecting apparatus and a program data change protecting method. The embodiments of the present invention relate to a technology for efficiently sensing and preventing abnormal data change by changing the data by only an allowable module and preventing the data from being changed by an unallowable module in a data area in which the data is frequently changed by executing a program. [Reference numerals] (AA) Start; (BB) End; (S100) Check data area in a memory of a protected program; (S110) Assign a read-only property to the data area; (S120) Check data change attempt?; (S130) Is it an allowable module?; (S140) Assign a writable property to the data area; (S150) Terminate data change?; (S160) Remove the writable property; (S170) Detect an abnormal attempt
