How to Make the Simplest Dongle Work for You
The simplest Dongle (SEETP-1 or SEETP-2 after programmed) described somewhere on this Website is a practically useful device that can be utilized to protect your valuable software. Even it’s undoubtedly a primitive one, if you decorate or make it appropriately, it can be an effective deterrent to the would-be pirate.
We all know that there is no absolute security device. Any mechanical or electronic lock can be unlocked by the appropriate key or code. From this point of view, the SEETP-1 or SEETP-2 Dongle is just another security device which plugs into the parallel port of a PC/Laptop and works with your software and protects it.
Because you’re a software writer, you know how to write C programs. We provide an example Dongle test executable file PDONG1TS.EXE or PDONG2TS.EXE for each aforementioned Dongle. Running this test program will give you an idea on how to incorporate the Dongle into your protected software.
We programmed some simple words such as “Hello. My name is Dongle, your security guard…” into the chip. The test program will read and verify these words. If verification is okay, the Dongle test is successful and your program can continue; otherwise your program will refuse to work and exit.
For the Dongle to act as a security device, you must keep it unknown to anyone else. Don’t tell anyone what chip you used, or what you’ve programmed on it. You need to blacken the chip’s designation. Also try to hide the printed circuit’s wiring. In a word, just make it as a tiny black box.
After doing so, the simplest Dongle will appear as a formidable guard. If someone has to spend hundreds of hour or lots of money to break it, that won’t happen easily.
