METHOD FOR DETECTING MODIFICATION OF COMPUTER PROGRAM EXECUTING IN MEMORY

摘要

PURPOSE: A method for detecting modulation of a computer program executed in a memory is provided to detect modulation based on original information of a computer program executed in a memory. CONSTITUTION: A protection target program is loaded in a memory(S211). An original storage code stores protection area information of the protection target program as original information(S212). A modulation detection program detects whether the protection target module of the memory is periodically modulated(S213-S216). [Reference numerals] (331) Original information; (S211) A protection target program is loaded in a memory; (S212) An original storage code of the protection target program stores original information; (S213) Comparing protection area information of the periodically loaded protection target program with original information; (S214) Identification?; (S215) Determining as non-modulated; (S216) Determining as modulated
