Method and system for preventing unwanted alterations of data and programs stored in a computer system

摘要

The present invention relates to a method and system for preventing the unwanted alteration of data and programs stored within a computer system. The system employs a field programmable gate array to control access to a storage device. Different profiles can be accessed through the use of passwords. Different profiles provide different control parameters for access to the storage device. The gate array can be reprogrammed from time to time using downloadable electronic files. Security is achieved in the download by using keys and encryption techniques.
