Abstract
A system for verifying data in a shadow memory is provided that includes a main memory, a shadow memory, a shadow memory initializer, and a shadow memory verifier. The main memory is operable to store main data persistently. The shadow memory is operable to store shadow data temporarily. The shadow data comprises a copy of the main data. The shadow memory initializer is operable to detect an initialization event and to initialize the shadow memory based on the initialization event. The shadow memory verifier is operable to detect a verification event and to verify the shadow data based on the verification event.
