In essence, it’s a bot trap developed to prevent bots or automated scripts from communicating with a website, online database, or from filling out a form online. The very first versions of the bot trap utilized a graphic design that twisted the letters and added background color. Because there was no way to program a computer system or compose a script that might address this bots were dropped in their tracks. Obviously, often people had issues seeing the image correctly.
Easier to see and utilize variations consist of fixing basic math problems such as 8 + 8 = or combining 2 words in such a way that computer would not be able to figure out. The most common method to do this is to produce an image that displays two words that are somewhat out of focus. The user has to go into both words as if they are one word to pass the test.
