A system for and method of graphic consistency verification for a replicated network having a plurality of existing applications. The system includes a graphic consistency autochecker and a plurality of application encapsulators. One encapsulator is distributed to and operates with each application. Each encapsulator includes an event tracker, an image catcher, and a signature calculator. The method includes the steps of receiving and multicasting input events from the user of one of the applications, capturing a graphic image from each of the applications, calculating an image signature for each graphic image, comparing all image signatures for consistency, and correcting any discrepancy when at least one of the applications has an inconsistent image signature before executing the next input event.
