Abstract:

Disclosed are a malicious code real-time inspecting device in a DRM environment and a recording medium for recording a program to execute a method thereof. A DRM module performs decryption and encryption during file reading/writing operations through a handle after confirming user rights relating to a file on the basis of a handle of a file having DRM applied when an execute command is inputted, outputs an inspection request message including a handle and a path of a file, and determines whether to perform an open operation of a file according to a malicious code inspection result on a file. A malicious code inspecting module inspects whether an original file, which is to be decrypted and read by the DRM module, is infected by malicious code or not on the basis of a handle and a path of a file in an inspection request message delivered from an interface module. According to the present invention, whether a document encrypted with DRM applied is infected by malicious code is inspected and treated in real-time.
