In today's software distribution, there is an increasing need to protect applications against illegal copying. AntiDuplicate is a useful tool to create hardware keys for your software protection - by your ordinary computer. With AntiDuplicate, software developers prepare hardware keys (dongles) from standard USB flash drives! The result is the durable compact media for software distribution and the USB token for anti-piracy protection at the same time. How does it works? AntiDuplicate determines specific physical characteristics for each USB flash drive. Due to this, your application can examine if the USB drive is your original drive or the copy. AntiDuplicate SDK contains instruments and samples for Visual C++, C++ .NET, C# .NET, Visual Basic, VB.NET, Borland Delphi and C++ Builder developers. Each SDK package is unique for each application! By using the SDK samples, you need to modify your executable file sources to enable reading the identification information from the USB drive. AntiDuplicate Drive Maker has supremely simple user interface and allows you to create a key USB drive in seconds. Unlike traditional dongles, AntiDuplicate drives need not any drivers or special installation, and they can still be used as USB mass storage devices.
