Abstract
A method for verifying computer generated data in periodically updated and replaced files to determine if data item characteristics in the files have changed in an unexpected manner. The method involves the steps of selecting a first version of each of the data item characteristics and selecting a second subsequent version of each of the data item characteristics. The first version of each of the data item characteristics and the second subsequent version of each of the data item characteristics are analyzed to produce first and second statistical profiles. The first and second statistical profiles of each of the data item characteristics are then compared to each other to determine if any of the data item characteristics have changed in an unexpected manner. Finally, the files being periodically updated and replaced are monitored to determine if the data item characteristics in the files have changed in an unexpected manner.
