Abstract
Programs running on an open architecture, such as a personal computer, are vulnerable to inspection and modification. This is a concern as the program may include or provide access to valuable information. As a defense, the actual location of data can be hidden throughout execution of the program by way of periodic location reordering and pointer scrambling, among other things. These techniques serve to complicate static data flow analysis and dynamic data tracking thereby at least deterring program tampering.
