Abstract
A method for validating program execution. The method involves identifying a program from a second computer system, obtaining, by a first computer system, a first copy of a page for a file of the program from a second computer system, calculating a hash value for the first copy, storing the first copy in a local memory of the first computer system, storing the hash value for the first copy, and executing the program on the first computer system, where the first copy is removed from the local memory during execution of the program. The method further involves obtaining a second copy of the page from the second computer system, calculating a hash for the second copy, determining whether the hash value for the first copy is equal to the hash value for the second copy, and performing an appropriate action in response to the determination.
