Anti Piracy Tools 2004 is a unique software protection system, allowing for live license management and illegal software serial numbers disabling. It offers an unprecedented level of protection for applications that require access to Internet. The system consists of client and server parts. The server part is installed on Microsoft IIS server. It handles the users' database, providing live licensing data to the client part. The client part acts real smart: once the application loads, it sends a query to the server including the current registration code and hardware hash. The server either responds with OK, or blocks given registration code, returning the reason for code lock-up.
