These years, the unstoppable progress of artificial intelligence and big data reveals the fact that traditional CAPTCHA is on the wane. Meanwhile, greater significance attached to verification security system drives a lot of companies to work hard on the next generation CAPTCHA. In this article, we’ll walk you through the advanced CAPTCHA created by GeeTest. Read on to know more.
When it comes to CAPTCHA, many people will think of reCAPTCHA from Google. As a matter of fact, CAPTCHA, also known as Completely Automated Public Turing test to tell Computers and Humans Apart, is an automatic public program to distinguish a user from a computer or a person. It is considered as an effective defense against malicious password cracking, ticket scalping, web scraping, account takeover and other actions performed by malicious computer programs. The general mechanism is that, a puzzle will be set by computers, and only human beings but not computers can work on it. In this way, CAPTCHA can easily detect and reach a conclusion the actual identity of the user.
The traditional CAPTCHA is mainly shown as some characters or numbers on a picture. In order to protect the security of verification, there are many ways to deal with traditional CAPTCHA code, including adding interfering lines and dazzling background, increasing noise, and distorting characters. These transformations are based on image recognition technology, mainly to increase the difficulty of cracking. For one thing, for many users, such conversion can be seen as a potential obstacle and sometimes can be really annoying. For another, it’s an undeniable fact that the recognition and cracking of traditional CAPTCHA code become much simpler and easier, and are even deemed to be the most basic cracking skills for both hackers and amateurs.
Character segmentation is dispensable for most recognition algorithms. As long as the characters on the CAPTCHA code can be segmented, the existing machine learning algorithms can generally achieve better recognition results. To a degree, this method embraces the same philosophy as the dimensionality reduction. Actually, if professionals apply deep learning, a fast-emerging branch of artificial intelligence, to carry out a mass of image recognition training, character segmentation will no longer be required and the recognition result can be improved to a greater extent.

It is easy to find out that traditional CAPTCHA code is not safe anymore on account of the development of artificial intelligence and an increasing number of cracking methods. The good news is: Powered by massive volumes of biometric data collected these years, GeeTest has GeeTest CAPTCHA to its credit. GeeTest is an expert with 7 years of experience in a security solution, whose driving force is to protect websites and mobile apps from abusive bot attacks with zero user friction. It has helped more than 260,000 websites or apps such as Binance, Airbnb, Huawei, Xiaomi, to defend different bot attacks. When faced with GeeTest CAPTCHA, the user is supposed to drag the missing piece of a puzzle and make it a complete one. Usually, the small jigsaw puzzle used is a cute or interesting cartoon. While its mechanism might seem very simple, the GeeTest CAPTCHA actually applies an incredibly sophisticated algorithm that analyzes data related to the speed and movements of your mouse, your typing speed, the time you spend on the form, and others. It uses these variables to determine whether you are a real person or not. In a word, GeeTest CAPTCHA code not only guarantees the security of the websites or mobile apps, but also saves much time for users. To create a better user experience, the company also adds gamification into its code, which makes solving CAPTCHA a fun and effortless experience.
Now that you’ve gone through the information we offer, we believe you can grasp a basic understanding of CAPTCHA easily. If you are the one who worries about the security of your website, maybe you can turn to GeeTest for help right now.
