As the world moves into new digital era, producing software, especially Internet software, becomes more and more profitable. The future looks bright, even for small software development companies, except for one fact. Software piracy (usage of stolen non-licensed software) is becoming one of the major headaches, these days. With information available to anyone anywhere around the globe it is obvious that once the stolen copy of the software or stolen registration code is published on one of so called 'warez' web sites, sales decrease dramatically.
