Title:
METHOD FOR DETECTING ACCESS OF AN OBJECT, COMPUTER THEREOF, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2012/053284
Kind Code:
A1
Abstract:
The objective of the present invention is to efficiently access an object. The present invention provides: a method for detecting access of an object, a computer thereof, and a computer program. The method includes: a step for manipulating a pointer to an object to convert the pointer to a pointer indicating a read/write-protected area; and a step for using the fact that an exception is raised in response to an access request to the read/write-protected area in order to reverse-convert the converted pointer to the original pointer. Also, the reverse-converting step may include: a step for referring to the command that caused the exception to be raised and acquiring the manipulated pointer from the command that caused the exception to be raised; and a step for reverse-converting the acquired pointer, acquiring a pointer to the start of the object indicated by the reverse-converted original pointer.
