Abstract

See full text

A system is provided for detecting pirated copies of a serialized software program. The system has a remote computer including a remote memory for storing a program, a remote revision level, and a program serial number. The system also has a main computer including a main memory for storing the program serial number, the remote revision level corresponding to the program serial number, and a validation code for a remote program corresponding to the serial number. The validation code indicates whether the program stored in the remote memory is valid or invalid. The system changes the validation code to invalid upon detection of a difference between the remote program revision level received from the remote computer and the remote program revision level stored in the memory of the main computer corresponding to the program serial number received from the remote computer. The system then detects whether the program stored in the remote memory is valid or invalid based upon the validation code corresponding to the program serial number. The system denies access to data stored in the memory of the main computer when the program corresponding to the serial number stored in the remote memory is invalid.
